Diamonds | Cubic Zirconia (CZ) |Gemstones | Pearls | Gold | Sterling Silver | Platinum | Sizing
Diamonds are formed between 75 and 120 miles (120 and 200 kilometers) below the surface of the earth. Made up of pure carbon, which crystallized under intense heat and pressure within the earth, diamonds were delivered to the surface by volcanic eruption.
Throughout history, diamonds have been a symbol of love and adornment. Like the people who wear them, no two diamonds are alike. When shopping for diamond jewelry, considerations of cut, color, clarity and carat weight - known as the "4C's" - will guide you in determining a diamond's quality and value.
Diamonds are the hardest of all substances on this earth. They are incredibly resistant to heat and scratching and can only be polished or scratched by another diamond, but an extremely hard blow to the girdle can cause a chip. By having your diamond placed in a protective setting your diamond can stay intact for a lifetime. Their sparkle, if cared for well, will remain undiminished for hundreds and hundreds of years.
The 4 C’s to Diamonds
There are 4 C’s to always keep in mind when purchasing a diamond.CARAT
The size and weight of a diamond is always classified by carats and points. One hundred points make up one carat. A diamond that weighs less then one hundred points is sometimes identified in point size, for example a .55 carat diamond can also be titled as a 55 pointer diamond.
A 1 carat diamond used to equal the weight of a carob seed, but today the carat is a metric weight of 0.2 grams, or 1/42 of a standard ounce.
When diamonds are mined, larger stones are found a lot less frequently then smaller stones making larger diamonds more valuable. Usually, the pricing of diamonds goes up with the carat size.
A diamond's weight is the easiest of its characteristics to measure. The word "carat" originates from a natural unit of weight, namely the seed of the "carob" tree. The pods of the carob, or locust tree, contain seeds which are remarkably consistent in weight. These carob seeds were used by the early gem traders to weigh their diamonds. Today, the system has been standardized and one carat is fixed at one-fifth of a gram.
Most diamonds contain tiny identifying marks called "inclusions." The fewer and smaller the inclusions, the less likely they will interfere with the stone's beauty.
Like a fingerprint, every diamond is unique. This could be due to minute traces of other minerals trapped in the diamond during its formation. The number, color, nature, size and position of any inclusion determine the clarity of a diamond.
The fewer the inclusions, the rarer it will be graded, and the more light it will reflect, thus making it more valuable. It is rare to find a diamond that has no inclusions, the closer to flawless the diamond is, the greater the value. IF through SI encompass 50% of all gem-quality diamonds.
The following chart shows the abbreviations and the definitions used in grading clarity:
The cut of a diamond, or the roundness, depth, width, and uniformity of the facets, determine a diamond’s brilliance. The width and depth have the greatest effect on how light travels through and exits a diamond in the form of brilliance. In a diamond that has been cut too shallow light is lost through the sides causing the diamond to lose its brilliance. In a diamond that is cut too deep; light will escape through the bottom causing the diamond to appear dark and dull. The proportions of a diamond, specifically the depth compared to the diameter, and the diameter of the table compared to the diameter of the diamond, determine how light will reflect and refract within a diamond. While nature establishes the color, clarity, and carat weight of a diamond a skilled artisan is necessary to unveil a diamond’s inner beauty. When a diamond is cut well, light reflects from one mirror like facet to another and radiates through the top of the diamond.
Diamonds come in many colors, but the overwhelming majority sold in the jewelry industry range from near colorless to very light yellow or brown. There are even colors called "fancy colors" such as pinks, blues, reds and even greens.
The best color choice in today's market for a diamond (unless a fancy color) is the lack of color. It is the diamond that is totally colorless that allows white light to pass through it, dispersed as rainbows of color.
Most diamonds look colorless, but there are many subtle shade differences and the closer a diamond is to having no color, the more valuable it becomes. D through G colors are the most valuable compared to N through Z colors, the least desirable. During the diamond's formation, in the extreme heat and pressure, traces of elements such as nitrogen and boron could have been incorporated into the diamond's structure. These traces are responsible for the color - or lack of it.
The following chart shows the color grading groups broken out by definitions:
In addition to the traditional brilliant round, diamonds come in a number of shapes. In fact, there are many shapes of diamonds; some of the most popular are: Round, Pear, Square or Princess, Heart, Marquise, Emerald and Oval, just to name a few. Care & Cleaning
Even though diamonds last forever, they must be cleaned periodically to ensure their brilliance. A solution of one part ammonia and six parts water can be used to clean diamond jewelry. It is also a good idea to have your diamonds checked once a year by a professional to ensure the setting is secure.
Cubic Zirconia (CZ)
Cubic Zirconia also known as CZ is created as affordable alternative for genuine diamonds. It is the most prominent choice among all fake diamonds. They come in every color imaginable at a fraction of the cost of other precious gemstones.
Because of its low cost, durability, and close visual likeness to diamond, synthetic Cubic Zirconia has remained the most geologically and economically important diamond substitute since 1976.
Chemically, Cubic Zirconia made up of Zirconium Oxide and Yttrium Oxide. The process however is quite complicated. When combined, the two chemicals create a beautiful, radiant crystal. It takes almost 5,000 degrees Fahrenheit to melt the two chemicals together and then they are cooled in a specific manner. The chemicals must be carefully cooled in order to create flawless CZ crystals.
Cubic Zirconias are not artificial diamonds, they are genuine Cubic Zirconia. CZs are an art in themselves. Manufacturers created the colorful Cubic Zirconias that we have today after the white Cubic Zirconias became so popular. The Cubic Zirconia is very dense and solid and would weigh 1.7 times more than a diamond of the exact size. They are cut the same way as diamonds. The only difference is that Cubic Zirconias are flawless and very affordable. With proper care, they will not lose their brilliance. Cubic Zirconias set in rhodium finished sterling silver looks just like diamonds set in platinum, and it will never tarnish.
The Cubic Zirconia CZ is a great substitute for diamonds when someone cannot afford a real diamond or just simply prefer not to spend the money on diamonds. CZ jewelry has a little less sparkle and brilliance, but has more fire and color. Cubic Zirconia CZ stones are durable, brilliant, and beautiful. People often cannot tell the difference between cubic Zirconia jewelry and diamond jewelry.
When purchasing a gemstone there are the five characteristics to consider:
The color of a gemstone it its most defining feature. When deciding upon a gemstone color it is important to look at its hue, tone, and saturation. The jewelry industry as a whole recognizes the highest quality gemstones by their green, red, or blue hue, a medium to dark tone, and saturated color. The most valuable gemstones exhibit a pure color and only slight hues of other colors in addition to their primary color. Tone represents the depth of the color, which can range from colorless to black. The tone of a gemstone is described as “light”, “medium-light”, “medium”, “medium-dark”, and “dark”. Color purity, or saturation, refers to the degree in which the gem is free of brown or gray hues. The gemstones that are most sought after show little gray or brown and are often referred to as having vivid or strong color saturation.Clarity
Gemstones form under unique circumstances and each individual gemstone is comprised of a combination of trace minerals that create identifying marks or inclusions in the gemstone itself. Gemstones that are flawless are very rare and valuable and even the most high-end gemstones are at least slightly flawed. The best value is found in gems that are lightly to moderately included.Size
Gemstones can be cut into a round, square, oval, or pear shape. The carat weight of a gemstone is not necessarily an accurate gauge for a gemstone only because all gemstones have different densities. Two gemstones that have the same carat weight may actually have a different weight.Enhancements
Almost all gemstones available have been enhanced. Gemstones that have not been enhanced are very recognizable because of their incredibly high cost. Some enhancements are an expected part of the polishing and finishing process and are accepted by the jewelry industry as a whole. Almost every ruby or sapphire that you would find has been heated. Heating completes a process that nature started, which is to enhance the gemstone to brilliant colors of blues and reds. Placing emeralds in oil has been going on for centuries and fills tiny fissures in emeralds to make them even more beautiful.Cut
Color saturation determines a gemstones cut. A greater color saturation requires a shallow cut, while less color saturation requires a deeper cut. With gemstones you will not find an ideal cut that is geometrically configured for brilliance like diamonds. To determine if a gemstone is top quality or not, in terms of its cut, look at the setting and make sure that all the facets are symmetrical. An asymmetrical cut crown indicates a gemstone of low quality. A well-cut gemstone is symmetrical and reflects light evenly across the surface and the polish of the stone is smooth without any nicks.

Gemstones should be cleaned with warm water, an ammonia based detergent, and a small brush. Always keep gemstone jewelry in a soft pouch and never let two pieces touch because scratching can occur.
A good rule of thumb is to make your jewelry is the last thing you put on before you start your day. Keep your gemstone jewelry away from hairspray, make-up, perfumes, body lotions, soaps and shaving creams. These can leave a residue on your gemstone jewelry that can be difficult to remove. Never wear your jewelry while doing rough work. A hard blow can chip a stone or break a prong thus a stone could be lost. All gemstones should be kept away from caustic household cleaning chemicals. Do not wear your gemstone jewelry while swimming in a pool or using a hot tub. Chemicals used in a pool or hot tub can damage the setting and your gemstones. It is generally best to clean you gemstone jewelry with warm water, mild soap (not detergent) and a soft toothbrush or artist's paintbrush. Be sure to plug the drain to save a dropped jewelry item. Use a toothpick to gently pry dirt from between prongs and under stones. Avoid vigorous scrubbing of oiled stones. Use a light touch with delicate filigree work, or on items with an oxidized finish. Give each piece a thorough rinse and dry them with an absorbent towel.
Take special care of Opals. The following tips on the care and cleaning of your opals will keep them beautiful for years to come: Wear it often; it likes to “breathe.” Touch it often; it likes contact with the skin. The natural oils in your skin keep the opal “moist” and lustrous. Be careful! Opals are delicate by nature and can crack easily if hit, banged or dropped. Do not wash dishes, clothes or other items with it on. Opals contain water. The harsh detergents in dish or laundry soaps can “dry” out the stone. Do not wear opals in any type of hot tub, Jacuzzi, swimming pool, sauna, steam room, bathtub or shower. Prolonged exposure and/or submersion in any water with or without detergents or chemicals will destroy opals. Do not garden with it on. Continuous contact with the soil can abrade the surface of your stone. Do not clean opal jewelry with an ultrasonic device. Use plain water and a good, nonabrasive hand or facial soap. DO NOT store your opal in oil or glycerin.
Pearls begin when a grain of sand, another piece of pearl, or any other irritant contained in the oyster’s shell. To protect itself the oyster secretes multiple layers of a calcium carbonate substance called nacre around the foreign object to isolate it from the rest of the oyster. After a few years, the original irritant is covered in a silky coat and that is a pearl.
Both natural and cultured pearls are born and grow inside live oysters. The difference between the two is that natural pearls are formed by nature, or by chance, and cultured pearls are made by man’s assistance by injecting an irritant into the oyster. Today, most pearls are cultured.
Although there is no official quality grading system for pearls (like the 4Cs for diamonds), there are several characteristics that affect their value which you should consider before making a purchase:
The surface shine that gives pearls their glow is known as its luster. The sharper the reflection of light on a pearl's surface, the more luster the pearl possesses.
Pearls have imperfections. These blemishes or marks on the pearl's surface should be minimal.
Perfectly round pearls are extremely rare, so they are naturally the most valuable. While most pearls appear to be round, only about 1% are actually perfect spheres.
Pearls can come in a wide variety of shades. The major color classifications are white, pink, silver, cream, gold and black. Finer quality pearls have an overtone, which usually appears toward the outside edge of the pearl. This can be rose, green or blue. Regardless of the overtone (shading), you should look for pearls with a deep, rich color that seems to come from within the gem.
Pearls are available in a wide range of diameters, from 3 to 7 millimeters in Freshwater pearls, 3.5 to 9 millimeters in Japanese Cultured Akoya pearls and 8 to 15 millimeters in South Seas/Tahitian pearls. While the size of a pearl is one of the most important factors in determining its value; a larger pearl may be less valuable if it lacks nacre thickness. A pearl that does not have many layers of nacre will crack and discolor over time, diminishing its value.
It is critical that the pearls in any strand or piece of jewelry be evenly matched in terms of their size, shape, color, luster, etc. Visible variations of these qualities not only affect the piece's beauty but its value as well.
A pearl's value is also based on its availability. Saltwater cultured pearls generally command higher prices than Freshwater cultured pearls, since a saltwater oyster can only produce one or two pearls at a time and a freshwater mussel can produce as many as 50 pearls at a time.
While, again, there is no official quality grading system for pearls, the most prevalent grading system used by manufacturers of pearl jewelry is the grading scale of "A", "AA" and "AAA."
- "A" - off round shape, surface may have small marks or imperfections difficult to see unless the pearls are studied closely, fair luster.
- "AA" - mostly round in shape, clean to mostly clean surface without significant imperfections, good luster.
- "AAA" - all round to mostly round, surface of the pearl is nice and clean, excellent luster (mirror-like uniformity-matching from pearl to pearl).
Therefore you may see a notation of an "AA" or "AAA" in our descriptions. You will also see, within that description, a full explanation.
Akoya Cultured Pearls
If you're looking for a classic look in pearls, look to Akoya Cultured Pearls. The Japanese Akoya is the most popular pearl seen in pearl strands and in earrings.
A cultured pearl is grown by nature with the help of man. This patented process involves the insertion of a "nucleus" (or irritant) into an oyster. In response to the invasion, the oyster coats the object with nacre. Nacre is a smooth, crystalline substance that surrounds the object and forms layers to protect the oyster's inner tissue (called the mantel) from further irritation. The result of this process is the beautifully luminescent gem we know as a pearl.
The Akoya cultured pearls are the specialty of Japanese pearl farms. Because Akoya pearls are high-quality pearls, you will find they are well matched for size, shape and color. You will also see few blemishes and a deep luster.
South Seas and Tahitian Pearls
South Seas Cultured Pearls come in shades of white, gold, brown and black. Sometimes know as Black Tahitian Cultured Pearls are among the largest and most valuable pearls and are found in the Indian and South Pacific Oceans. They are typically larger than Japanese pearls, with diameters measuring from 8.5-15MM. Their color is acquired from a black-lipped oyster found only in the South Seas. Although these pearls come in various shapes from baroque to round, the round shape is the most valuable.
Freshwater Cultured Pearls
Freshwater Cultured Pearls are often called Biwa pearls because Lake Biwa (in Japan) was one of the first freshwater culturing areas. Today they are farmed in many areas around the world including some areas in the United States. Only those pearls actually produced in Lake Biwa should be called Biwa Pearls. All others are simply Freshwater Cultured Pearls. These pearls mainly range in size from 3-7MM and are available in an almost unlimited variety of shapes and natural colors.
Mabe (pronounced mah-BEE
These pearls have a half-sphere shape that is formed by the pearl being cultured against the inside of the oyster's shell.
Care & Cleaning
Pearls are very soft and need special care and attention. You should never store your pearls in a jewelry box next to other jewelry, because both the box and other pieces of jewelry can damage pearls by scratching and nicking, so keep them in a fabric lined box or fabric pouch.
Skin produces acids that can harm your pearls, so if worn regularly pearls should be wiped down with a soft cloth after every wear. A pearl necklace will gradually absorb acid from the skin that will eat into the pearl causing it to lose its luster. Wiping pearls of with either a wet or dry, soft cloth will prevent dirt from accumulating and keep perspiration, which is slightly acidic, from eating away at the nacre. If you desire you can even use a drop of olive oil on your cleansing cloth to help maintain your pearl’s luster.
Along with being soft and easily scratched, pearls can be damaged by chemicals and heat. Only use jewelry cleaner is clearly marked safe for pearls. Never use ultrasonic cleanser. Never use dish or wash detergents, bleaches, baking soda or ammonia based cleansers. Never use toothbrushes, or any other abrasive materials to clean your pearls. Always take off your pearls before you use any cosmetics, hair spray, and perfume. Avoid heat and dry air because both can cause pearls to turn brown, dry out, and crack.
Gold’s softness and malleability makes it the perfect metal to create jewelry. It is also nontoxic, resists tarnishing, doesn’t corrode, is hypoallergenic, and retains its value making it very popular to wear. Pure gold is too soft to withstand prolonged handling. It is usually mixed with other metals to increase its hardness for use in jewelry. The gold content of a piece of jewelry is measured in karats, which can range from 1 to 24. For example, 14 Karat (14K) gold is 14 parts of gold to 10 parts other metals. The higher the karat of a piece of jewelry, the greater its gold content.
Please Note: The term Karat should not be confused with the term Carat, which is a measure of the weigh
t of diamonds and other gemstones.
24 Karat - 100% gold
- This is too soft for jewelry.
18 Karat - 75.0% gold
- This is recommended for fine jewelry.
14 Karat - 58.3% gold
- This is recommended for fine jewelry. (most common)
10 Karat - 41.7% gold
- This is the lowest legal karat considered real gold in the United States.
Most gold used in jewelry is alloyed with silver, copper and small amounts of zinc to produce various shades of yellow gold, or with nickel, copper, zinc and rhodium to produce white gold. The color of these gold alloys goes from yellow to white as the proportion of nickel in them increases. Alloying gold with copper creates what is known as rose or pink gold.
Since nickel is the most popular alloy used in white gold, it is important to note that some people may be allergic to nickel. People with this sensitivity can avoid problems by choosing 18-Karat gold, instead of 14-Karat (since there is more pure gold and less alloys in 18 Karat gold), or by choosing platinum settings. (See additional information on Platinum below.)
You will find 18K and 14K yellow gold at JewelStop.com. 18K gold contains more precious metal than 14K gold. It is composed of 75% gold, which is alloyed with other metals to make it strong enough to withstand everyday wear. Because 14K gold is composed of only 58.3% gold, and 41.7% other metals that give it strength, its gold color is not quite as rich as 18K gold but is still a lovely gold. The alloys used to strengthen 18K and 14K gold are silver, copper and small amounts of zinc.
When gold is mined, it is yellow in color. Because 18K white gold is 75% gold and 14K white gold is 58.3% gold, jewelry made from these metals has a slight yellow color. Alloys are added to the gold to give it strength. To enhance the whiteness, almost all white gold is plated with rhodium. Rhodium is a shiny white metal that is extremely hard. Depending on the amount of wear to a piece of jewelry, over time this rhodium plating may wear off, revealing the original metal color. Re-plating is a simple process that can be done to restore your jewelry's whiteness if needed.
Rose or Pink Gold
This gold is known by both names: rose or pink gold and gets its color from a larger proportion of copper in the metal alloy. This gives the gold a beautiful pink or rose color.
The price of gold jewelry depends upon the purity of the gold used (karat weight of the gold), the design and construction of the piece of jewelry. Care & Cleaning
Since gold is so durable and malleable it is ideal for settings containing diamonds, pearls, or gemstones. Always keep gold clean and never use harsh chemicals to clean it with. Gold can easily be scratched so keep it is a fabric lined case and away from other jewelry. If a piece of a setting breaks you can always take it to your jewelry professional and have it repaired.
The following is a simple guideline to help keep your gold jewelry looking great for years:
- Don't wear your jewelry while doing rough work. Even though most gold jewelry is durable, a hard blow can, for example, break a prong on a setting or deeply scratch the piece.
- When doing household chores, never allow your jewelry to come in contact with chlorine bleach. To be safe, always wear gloves or remove your jewelry before beginning the work.
- Bring your jewelry to a qualified bench jeweler (one who makes or repairs jewelry) if you notice a loose stone setting, stones moving within a setting, a loose or weakened link or any other noticeable damage to your jewelry. It is a good idea to have a jeweler (or bench jeweler) check the setting in your diamond ring (while you watch) once a year.
- Always remove your jewelry before bathing and grooming. Think of your jewelry as the final touch and put it on right before you get on with your day. Hairspray, body lotion, moisturizer, perfume, mousse, make-up, shaving cream and soap are chemicals that can leave a residue on jewelry, creating a dull film that is difficult to remove.
- Never swim in a swimming pool or use a hot tub while wearing your jewelry. Chemicals such as chlorine can pitt your jewelry and can damage white gold. Further, concrete (such as pool decks) are rough surfaces. Allowing gold jewelry to come in contact with rough surfaces can cause scratches and mars.
- Keep it dry. Using water to clean and rinse some of your jewelry is permissible; however, make sure it is dried thoroughly when you have completed the cleaning. Always make sure your jewelry items are thoroughly dry before placing them in an enclosed area, or your jewelry may get water spots.
Silver is now the metal that is mostly used throughout the world, but it was one of the first metals to be used and can be traced back to the ancient Egyptian, Phoenician, and Byzantine empires. The work of silver was also popular in colonial America where it developed along other craft traditions.
In its purest state, silver can be as soft as gold and therefore it is generally alloyed with another metal, usually copper, to add strength. Karatage is not used when technically speaking about silver because any piece of silver or sterling silver must be 92.5 percent pure to be considered real silver. The finish of silver can be polished to a high sheen that not even platinum can match. The finish can also take on different textures when made into jewelry like polishing, matte or brushed, sandblasted, oxidized, or antiqued.
Rhodium Plated is a tarnish free finish. Care & Cleaning
Silver requires more maintenance than any other metal. Tarnishing occurs because silver reacts to pollutants in the air, which is then exacerbated by moisture and heat. Tarnishing can be removed by chemical tarnish removing solution.
Platinum was considered the precious metal of choice for discriminating jewelry purchasers in the beginning of the 20th century. When World War II began, Platinum was declared a strategic metal to be used for military purposes only. During the war, white gold gained popularity to fill the gap left by Platinum's absence. Today, Platinum is regaining its popularity as one of the hottest precious metals on the market.
Many don’t know that Platinum jewelry is 50 times more rare than gold jewelry and one of the world's strongest metals. It weighs 60% more than karat gold. Just holding it in your hand, you can feel the difference.
Being hypoallergenic precious metal you can wear it and not have to worry about an allergic reaction on their skin. They can also wear Platinum if they are allergic to nickel (an alloy frequently used in karat gold) without an allergic reaction to the skin.
Platinum is a naturally white metal. When Platinum comes out of the ground, it is white. When gold comes out of the ground, it is yellow and must be bleached or dyed white with other metals such as nickel and rhodium in order to create white gold. Platinum will always stay white. It needs no special maintenance over the years to remain that beautiful white color.
Platinum is durable. Not only does Platinum feel heavier than gold, prongs are stronger and therefore more securely hold precious stones in place and require less maintenance than karat gold prongs.
Look for markings on Platinum jewelry that tell you it is Platinum. Iridplat, 900 Plat or 900 PT are markings that mean that the alloy mix is 10% iridium (a platinum group metal) and 90% pure Platinum. PLAT, 950 Plat or 950 PT are markings that mean a piece of jewelry is 95% pure Platinum and 5% another metal. The other metals are usually ruthenium or iridium (both Platinum group metals).
The newest, exciting addition to the jewelry family is Karat Platinum. Simply put, Karat Platinum is made with the same eye toward affordability while maintaining the beauty and luster of Platinum as is 14K gold. As 14K gold is marked 14K or 585, Karat Platinum is marked 585Pt/415CoCu. The alloys used in creating Karat Platinum (or 14K Platinum), that give it durability and strength while maintaining the luxurious Platinum luster, are typically cobalt and copper.
Not everyone can own Platinum jewelry because there simply isn't enough of it in world. For example: all the Platinum ever mined would fit in an average sized living room.
Care & Cleaning
Like all jewelry, you will want to put your platinum jewelry on as the final touch before your begin your day. While platinum is a much harder metal than gold, it can still show scratches. Therefore, you should not do any household or rough work while wearing platinum. Soaking your platinum jewelry in a mild solution of warm soapy water and gently scrubbing it with a soft brush (makeup brush) is generally all that is required to keep your platinum looking beautiful for years.
