On the Mohs Scale, which measures the hardness of minerals, cubic zirconia is an 8.0 to 8.5. It is important to understand that hardness is not necessarily related to durability. Even though diamond is the hardest mineral (10.0 on the Mohs Scale), it can still be chipped or broken.
The only ways to tell the difference between cubic zirconia and diamond are by use of a thermal probe, by weighing the loose stone or by microscopic examination of surface features and inclusions. Cubic zirconia weighs approximately 65% more than diamond. Therefore, while a 6.25 mm round diamond weighs about 1.00 carat, the same size cubic zirconia weighs about 1.65 carats. If you know the weight of a cubic zirconia, you can figure out the diamond weight equivalent by multiplying the cubic zirconia weight by 0.6, or 60%.
Few natural diamonds on the market today are perfectly cut, and those that are cost much more than the usual diamond. Unleashing the fire, beauty and brilliance of a stone depends on its precise cut. Simulated diamonds are an excellent balance between quality, beauty and price.
Brilliance: The white light leaving a jewel, traveling upward, which is visible to the eye. Brilliance is sometimes referred to as “sparkle.”
Dispersion: Flashes of rainbow colors. Also called “fire.”
Hardness: Resistance to scratching. The higher the number, the more resistant.
Luster: The shininess of a jewel.
Toughness: Resistance to breakage.
Amethyst, the most precious member of the quartz family, exhibits purple shades ranging from pale lilac to deep purple, sometimes exhibiting reddish or rose overtones. Very deep-colored amethysts are the finest and most highly valued. Some stones are so over-saturated with color they have areas that are blacked out, which can negatively impact their value. Paler shades, sometimes called "Rose of France," were common in Victorian jewelry. Banding—darker and lighter zones of color—is also a common occurrence. Occasionally, amethyst is even found combined with its sister quartz, citrine, into a single stone called ametrine.
The birthstone for February, amethyst is an extremely popular gem for jewelry because of its regal color, variety of sizes and shapes, affordability and wide range of hues. It also is the recommended gem for couples celebrating their 6th and 17th wedding anniversaries. With a hardness of 7.0 on the Mohs Scale , amethyst can occur as long prismatic crystals that have six-sided pyramids at either end, or can form as drusies that are crystalline crusts that only show the pointed terminations.
The ancient Greeks believed that amethyst made one immune to the effects of alcohol. In fact, the name even comes from the Greek word amethystos, which means “not drunken.” Legend has it that the amethyst originated from Bacchus, the god of wine. Bacchus became angry at the mortals and vowed that the next mortal to cross his path would be eaten by tigers. Amethyst, a beautiful young maiden, was on her way to worship the goddess, Diana. Diana turned her into colorless quartz to keep her from being eaten. Bacchus observed the miracle and repented his hasty decision. He poured wine over the young maiden, leaving her feet and legs colorless. This is the reason that amethyst crystals are usually uneven in color and have a colorless base at the bottom. Because amethyst was believed to prevent drunkenness, wine goblets were often carved from it in ancient Greece. Today, the gem still symbolizes sobriety.
Amethyst has been a part of history throughout the ages. Evidence suggests that prehistoric humans used amethysts for decoration as early as 25,000 B.C. Legends suggest that the Egyptian queen Cleopatra wore an amethyst signet ring, as did Saint Valentine, who bared an amethyst engraved with the figure of Cupid. During medieval times, people used the stone as medication to stay awake and alert. Leonardo Da Vinci claimed that amethyst could dissipate evil thoughts and quicken the intelligence. In some legends, the stone represents piety, celibacy and dignity. In the Middle Ages, for instance, the gem was an important ornamentation for the Catholic Church and other religions. It was considered the stone of bishops, and they still often wear amethyst rings. In Tibet, amethyst is considered sacred to Buddha and rosaries are often made from it. Amethyst has also long been a favorite of kings and queens for its royal purple hues that symbolize wisdom, strength and confidence. Amethysts are even featured in the British Crown Jewels and were worn by Catherine the Great.
Amethyst’s availability and magical qualities make it the stone of preference in ancient lore and mysticism. As a meditation stone, it is said to quiet the mind, promote contemplation, sharpen psychic powers and uplift the spirit. It is a stone of deep wisdom. Folklore says it can quicken the wit, calm fears, ward off anger and overcome alcoholism. It has a royal purple essence that is said to lend courage to travelers, scare off thieves and protect travelers from harm, sickness and danger. Placed under the pillow or worn to bed, there are claims it promotes peaceful sleep, pleasant dreams, and the healing of tired joints and muscles. Amethyst can also be worn to supposedly make the wearer gentle, amiable and happy.
The stone is mined in Brazil, Uruguay, Bolivia and Argentina, as well as in Zambia, Namibia and other African nations. Very dark amethyst in small sizes also is mined in Australia. But the ideal for fine quality amethyst was set by a Siberian variety, often called Russian or Uralian amethyst, which is now considered a defunct source. Generally, South American amethyst tends to come in larger sizes than African amethyst, but the African variety has a reputation for having deeper color intensity and is therefore considered more valuable. The African version also is harder to come by than amethyst mined from South America. Most of today's amethyst comes out of Brazil.
Named from the French word for lemon, “citron,” citrine is a variety of quartz available in a range of golden hues from lemon, to straw, to sun yellow, to deep gold, to orange, brown and deep red. Darker colors are more highly valued, including the medium golden-orange and dark-sherry colors, sometimes called Madeira citrines after the color of the wine.
Citrine crystals can form together with amethyst to form ametrine, or with smoky quartz to form bicolored quartz. Citrine is generally less expensive than amethyst, and is also available in a wide range of calibrated sizes and shapes, including very large sizes. Considered an alternative to topaz as the birthstone for November, it is also thought to be the traditional gift for couples celebrating their 13th and 17th wedding anniversaries. Citrine ranks a 7.0 on the Mohs Scale, and because of this durability, it is ideal for jewelry wear.
Almost all citrine on the market is heat-treated amethyst, and generally starts life as either smoky quartz or amethyst geodes. Heat treatments first turn them clear and then give them a permanent color ranging from yellow to brownish-red. In some amethyst deposits, the amethyst has been partially or fully changed to brown citrine by natural means of heating, thereby transforming it into citrine. Natural citrine is pale yellow to orange, and occurs in much lighter hues than the heat-treated material. Citrines whose colors have been produced by artificial means tend to have much more of an orange or reddish caste than those found in nature. Since most citrine was originally amethyst that was heated to turn its color to gold, both citrine and amethyst jewelry should be kept away from prolonged exposure to strong light or heat.
Most citrine is mined in Brazil, but almost all of the Brazilian material is heat-treated amethyst. Supplies are most plentiful in the Brazilian state of Rio Grande do Sul, particularly from the Serra Mine. The Ira' Mine also produces large quantities of the gem. Citrine can also be found in the Ural Mountains of Russia, in Dauphine, France, and in Madagascar.
In ancient times, citrine was carried as a protection against snake venom and evil thoughts. It was thought to give calmness and mental balance to its wearer. Throughout history, people have confused citrine for topaz. Many citrines were sold as topaz and thus thought to carry the same qualities, such as knowledge and beauty. Today, citrine symbolizes truth and integrity, and is believed to promote creativity and personal clarity.
Often referred to as the “Queen of Garnets,” rhodolite is the violet-red variety of the garnet family. Its most prized color is a beautiful raspberry, but the gem can also be found in shades of pink, red and wine. The name is derived from the Greek words “rhodon” and “lithos,” meaning rose-stone, which connects the gemstone today with the raspberry-pink flower known as the rhododendron.
Rhodolite is a combination of almandine and pyrope garnets. Although it is occasionally found in volcanic rock, the stone is most often found in alluvial deposits in the form of water-worn pebbles. For this reason, large solitaires weighing 5.00ct or more are seldom seen at retail. Most rhodolite is mined in Sri Lanka, Tanzania and Zimbabwe. It ranks a 7.5 on the Mohs Scale and is ideal for jewelry.
The ancients wore rhodolites as amulets for protection from injury or death in battles. Modern folklore says rhodolite can help one understand dreams, as well as bring about love and devotion when given as a gift.
A symbol of strength and intelligence, topaz derives its name from Topazios, an island in the Red Sea that is known today as Zabargad. The Greek word “topazios” means “to seek,” since the island was covered with a thick fog and difficult to find. Gemstones found on the island were called topaz, although the stones were eventually found to actually be peridot. The real gem of topaz is found throughout the world, with different occurrences producing specific colors.
Brown, yellow, orange and red topaz are found in Brazil, Sri Lanka and Siberia. Most brownish topaz is heated to produce a permanent and glamorous pink color. Following the discovery of pink topaz in Russia during the 19th century, Imperial topaz was found. Featuring a sherry red, deep pink or reddish-orange color, the gem was so coveted that its ownership was restricted to the Czar, his family and those who received it as a royal gift. Today, Imperial shades are the most rare and, therefore, the most valuable.
Blue topaz is rarely found in nature and is most often created through a combination of heat treatment and irradiation. It is found in Brazil, Sri Lanka, Nigeria and China. Topaz is often colorless, too, and can be found in the United States, Mexico, Russia and Pakistan. In 1998, a new type of enhanced topaz made its appearance with a greenish-blue or emerald green color. All colors of topaz rank an 8.0 on the Mohs Scale of hardness.
Yellow topaz is November’s birthstone and blue topaz is December’s birthstone. Blue topaz is also the traditional gift for 4th and 19th wedding anniversaries, while Imperial topaz is celebrated as a 23rd anniversary gift. Perhaps the most famous topaz is a large, colorless stone known as the Braganza. It was discovered in Brazil in 1740 and was originally thought to be a priceless diamond. Today, the giant 1,680.00ct stone is set in the Portuguese Crown.
The mystery and allure of topaz goes back thousands of years. To the ancients, it was a symbol of love and affection and was thought to ward off sudden death. The Romans associated topaz with Jupiter, the god of the sun. The Greeks called it the Stone of Strength, believing it had the power to increase strength and make its wearer invisible in times of emergency. The Egyptians said the gem was colored with the golden glow of the sun god, Ra, making topaz a powerful amulet that protected its wearer against harm.
Topaz’s mystical curative powers were believed to wax and wane with the phases of the moon. The gem was said to change color in the presence of poisoned food or drink and falcons were carved on the stones to help earn the goodwill of kings and magnates. During the spread of the Bubonic plague in 1347-1400, the clergy touched topaz to people’s sores. Also in medieval times, the gem was thought to prevent death and heal physical and mental disorders. The stones were ground into powder and added to wine to prevent asthma and insomnia.
Today, topaz is said to be the gem that has the widest range of curative powers. It is believed to dispel enchantment, improve eyesight and protect against negative emotions such as depression, anger, fear, greed and envy. Its properties are supposedly enhanced when the gem is mounted in gold. Because of this association with gold, topaz is used to bring or enhance the wearer’s money-gathering abilities and has long been used in money and wealth rituals.
Wearing topaz is said to improve and deepen relationships, promote patience, ensure fidelity and enhance the ability to love. The gem is also believed to bring friendship, intelligence, long life, beauty and a pleasant disposition.
Chrome diopside, also called Russian diopside, offers an intense forest green color. Because it is the most affordable gemstone with a pure, rich green color, many jewelry designers predict chrome diopside will be the world’s leading emerald substitute by the end of the decade. It is mostly available in smaller sizes, with the rare larger sizes becoming much more expensive and too dark. A 26.17ct oval cut chrome diopside may be the largest known example of the faceted stone, but there is also a 25.33ct stone that is brighter and more intense in color.
Chrome diopside is relatively soft, with a hardness of 5.5 on the Mohs Scale. Mostly mined in Yakutia and Siberia, the liberalization of the economy of the former Soviet Union has made chrome diopside more available, and more popular, than ever before.
Garnet comes in a vast rainbow of naturally exquisite hues, occurring in every color except blue. It is the family of minerals that displays the greatest variety of colors than any other mineral. The eight major types of garnets include almandine, pyrope, demantoid, grossularite, tsavorite, hessonite, rhodolite and spessartite.
Named after the ancient gemstone city of Alabanda in Asia Minor, the most common type of garnet is almandine (also called almandite). It is a dark red to brownish red stone that is only slightly different from the chemical structure of its sister stone, called pyrope. While nature only grows pyropes in small sizes, it allows for almandine crystals to form in larger dimensions.
Pyrope is a high-quality garnet that can be purplish red, blood red, orange-red or crimson. It is often called the Bohemian garnet since its fierce and often slightly bronze color was highly popular in the 18th and 19th centuries when it came from the north-eastern part of the former Kingdom of Bohemia. In Europe during the Victorian times, pyrope garnets frequently decorated jewelry with many of these small stones tightly arranged along each other like the seeds of a pomegranate. In fact, the name “garnet” most likely was derived from the pomegranate, a fruit whose deep, red-purple color resembles some varieties of the gem. Many ancient pieces of garnet jewelry are also studded with the tiny red gems.
Demantoid is a rich green variety of garnet primarily found in the Ural Mountains of Russia. Russia’s leading court jeweler, Carl Fabergé, loved this brilliant garnet more than any other stone and used it in many of his creations that were lavishly adorned by the Tsars of Russia. Today, demantoid is appearing more often in the gemstone market because of new finds in Namibia. However, these particular garnets from Namibia lack "horsetail-inclusions,” the fine bushy-shaped inclusions that are characteristic of the sought-after Russian demantoids. The gem is quite rare and can cost several thousand dollars per carat depending on size and quality. The larger, brighter demantoids are exceedingly scarce and have been known to show exceptional brilliance, even higher than diamonds.
Grossularite, available in pinks, browns, greens and yellows, is especially cherished because of its many in-between shades and earth colors. In the last year of the 20th century, large grossularite occurrences were discovered in Mali. Charming because of their high brilliance, the Mali garnets make even the brown color attractive and vivid.
Tsavorite is the trade name for a fine green grossularite. It ranges from vivid light green to velvety deep green and, like all other garnets, features a strikingly high brilliance. Tsavorite was discovered in 1967 by British geologist Campbell R. Bridges, and was re-named by Tiffany’s in New York after its occurrence near the famous game park Tsavo-National Park. Mined in Tanzania and Kenya, this particular stone is quite rare and can cost several thousand dollars per carat depending on size and quality. Larger tsavorites are exceedingly scarce.
Hessonite is the variety name for a fine orange, cinnamon brown or pinkish variety of grossularite. It most commonly occurs in golds, oranges and browns.
Rhodolite is a pyrope-almandine garnet that features a velvety red color with a fine purple or raspberry colored undertone. One of the most popular varieties, it is mined in East Africa, India and Sri Lanka and was originally discovered in the United States.
Spessartite garnet can be red or blackish brown, but is most commonly available in golds, oranges and warmer browns. Originally named after its occurrence in the German Spessart Mountains, there was a surprising discovery of the bright orange-red stone in Nigeria and Namibia. Until then, spessartites had existed as mere collector’s items or rarities and were hardly ever used for jewelry because they were so rare. But the new location discovery changed the world of jewelry gemstones and spessartites made their way into jewelry fashion. The most popular type of spessartite is the mandarin garnet, a gem that features a bright orange hue.
Traditionally given as 2nd wedding anniversary gifts, garnets are celebrated as January’s birthstone. They are found all over the world, including Africa, Australia, Eastern Europe, the Middle East, North America, South and Central America, and Southeast Asia. The garnet ranges from 7.0-7.5 on the Mohs Scale and has been given many different names throughout the gemstone trade, including Arizona Ruby, Arizona Spinel, Montana Ruby or New Mexico Ruby. The stone features a high refraction of light that creates an amazing brilliance and luminosity. In fact, Noah used a garnet lantern to illuminate the darkness and navigate the Ark through 40 days and nights of torrential rain.
Throughout history, garnets have been widely known and prized for their rich hues and supposed mystical properties. Adored by the ancient Egyptian goddess Isis, the gem symbolized faith, truth and friendship and was a favorite of Egyptian jewelry artisans. Garnets were taken into the tombs with the dead as payment to the gods for safe passage through the nether world. It is said that King Solomon wore a large red garnet along with eleven other magical gems in his breastplate (representing the 12 steps of Jacob's Ladder) to help him win battles. Nineteenth-century Asiatic warriors even used the hard stones as bullets. In the 13th century, medieval travelers wore garnets as popular talismans and protective stones, many of which were carved with lions. The gems were thought to repel evil spirits, bad dreams and people with evil intent.
Today, garnets are thought to have protective powers and can be carried by travelers to protect against accidents. The stone is said to light up the night and protect its owner from nightmares. It is also believed to strengthen the body and mind by sparking creativity, dispelling anger and curing depression. People may use the stone to increase the power of their energy fields and gather good vibes. Current superstitions say that the stone symbolizes loyalty and can be exchanged between friends to symbolize affection and ensure they meet again. When used as a healing stone, it is said to relieve skin inflammations and regulate blood flow.
Stainless steel, also called corrosion resistant steel, is a steel alloy with added iron and chromium. The metal is low maintenance, rust-resistant, durable, highly lustrous and extremely hygienic, making it ideal for items such as cookware, knives, surgical instruments, jewelry and watches.
The nearly-indestructible and masculine nature of stainless steel is appealing for many jewelry styles. It has a similar appearance to platinum and polishes to a glistening sheen. Any scratches that may occur from day to day wear can be easily buffed away without endangering the piece. Unlike traditional gold, silver or platinum jewelry, stainless steel jewelry is not poured into molds, but is usually hand-cut from a solid piece of steel, leaving no seams or weak spots. With stainless steel, your jewelry will last a lifetime.
Stainless steel was first recognized in France in 1821 by metallurgist Pierre Berthier. He realized the iron-chromium alloys maintained resistance from acids and recommended their use in cutlery. After several corrosion-resistance related discoveries and patents in Europe and the United States, Harry Brearley in England discovered a modern blend of stainless steel alloy. When it was announced by The New York Times in January of 1915, he was officially credited with the invention of this impressive modern metal.
