Sterling silver, also called fine silver, is a beautifully lustrous cool-toned precious metal favored in fine jewelry among other products. The most reflective of all metals (excluding mercury), sterling silver looks stunning by itself and brings out the best hues in an array of colorful gemstones.
Sterling silver can be polished to a higher sheen than platinum. In fact, Ag, the chemical symbol for silver, comes from a word that means “white and shining.” The surface of silver can boast that shiny, polished appearance, or can be brushed, satin, matte, sandblasted, antiqued or oxidized (chemically blackened).
In order to be called sterling silver, a metal must be made up of a minimum of 92.5% pure silver and 7.5% alloy (meaning other metals), including but not limited to copper and nickel. The alloy is added to pure silver to make the metal more durable, tougher and harder. Sterling silver is designated a fineness of “925.” Pieces with sterling silver may be marked “sterling.”
Finishes on Sterling Silver
Finishing, or plating, is a common treatment with sterling silver. Popular types of plating are rhodium plating, gold plating and anti-tarnish plating. Plating is used to extend the life and sheen of the jewelry. After sizing or buffing a piece of jewelry with a machine, it must be re-plated to restore the finish.
Caring for Sterling Silver
Sterling silver becomes tarnished as the result of a natural chemical process that occurs when sterling silver is exposed to chemicals in the air, rubber, wool and latex. Humidity also plays a role in accelerating tarnishing. It's easy to keep your sterling silver sparkling, though, by taking a few steps to prevent tarnish and other wear and tear.
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.
Tourmaline occurs in virtually every color of the spectrum, with an unlimited range of solid and mixed colors in all imaginable shades. According to an ancient Egyptian legend, this is the result of the gemstone traveling along a rainbow from the Earth's heart, up to the sun. On its journey, the legend says that tourmaline collected all the colors of the rainbow, which is why it is called the "Rainbow Gemstone."
The gem is found in hues of red, pink, green, blue, yellow, black, brown and colorless. It also can be bi-colored or multi-colored. Some tourmalines are very faint in color, while others are so dark that the color is only discernible when light is shone through the stone. There are even tourmalines that change their color from daylight to artificial light.
Tourmalines displaying just one color are quite rare since one crystal usually shows two or more shades or colors. In fact, the name "tourmaline" has been derived from the Singhalese expression "tura mali," which translates to "stone of mixed colors." Even two stones cut from the same rough mother crystal will often show different colors, a characteristic that makes tourmalines so attractive and sought-after.
Tourmaline also shows a remarkable dichroism. This means that when viewed from different directions, the stone will display different colors, or at least show different intensities. The deepest color always appears along the main axis, a fact that is important for the gem cutter to focus upon when cutting the stone. Tourmalines rank a hardness of 7.0-7.5 on the Mohs Scale and may be as small as a knitting needle or as thick as a thigh. They are easily available in sizes of up to 5.00ct.
Different shades of colored tourmalines have been assigned specific names in the gemstone world. Bi-colored and multi-colored tourmalines have several names for the common combinations of colors. Crystals with red or pink cores and green borders are called watermelon-tourmalines. Stones with colorless crystals and black tips are called Maur's Head or Moor's Head, while colorless crystals with red tips are called Turk's Head. If the color zones are arranged one on top of the other, the stone is considered a rainbow tourmaline.
The red variety of tourmaline changes its name based on the coloring in different types of lighting. Deep red tourmaline named rubellite shows the same fine ruby-red shade in daylight and in artificial light. Should the color change when the source of light changes, the stone is simply called a pink tourmaline. With its exquisitely intense coloring, rubellite was once the victim of misidentification for rubies in the Russian crown jewels.
Green tourmalines come in a variety of shades, including leek-green, intense yellow-green, olive-green and brownish-green. Chromium-tourmaline is the trade name for the emerald-green variety. Its beautiful color is strikingly similar to the fine color of emeralds. Blue-green and dark bottle-green are the most rare and highly coveted green hues.
Perhaps the most beautiful variety is the Paraiba tourmaline. It ranges in color from electric blue to neon blue-green to sizzling turquoise. Discovered in the Brazilian state of Paraiba, its vivid color has not been consistently seen in any other gemstone variety. Its spectacular color is due to the presence of a small amount of copper. A study by the German Foundation for Gemstone Research also discovered a surprisingly high content of gold in the stones.
Until recently, there was one striking gap in the range of colors displayed by tourmaline. Pure yellow shades were missing and most of the yellow tourmalines that were found showed a slightly brownish tinge. In the year 2000, however, electric yellow tourmalines were found in Malawi in East Africa. With a clear and pure color, they were deemed "canary tourmalines" and the formerly missing color of yellow was added in excellent quality to the unlimited range of tourmaline colors.
Larger yellow tourmalines rarely occur. Only 10 percent of all the mined yellow stones are gem-quality and when cut, more than 95 percent of the harvest will weigh less than 1.00ct. Regardless of their smaller size, experienced cutters love working with the stones. Not only do they have brilliant color, yellow tourmalines are considered to be the only gemstones that have a fine scent. This is because in the place of their occurrence, tourmaline crystals are often embedded into black material that must be removed before the stones are cut. An owner of a Malawi gemstone mine discovered the black matter was easily removed when the rough crystals were boiled in water and lemon juice. Ever since then, yellow tourmalines from Malawi not only resemble fresh lemons in color, but also in their scent before they are cut.
Other tourmalines are called "indigolith" if they are blue and "dravite" if they are golden to dark brown. Black tourmalines are known as "schorls" and are mainly used for engraving. Although they were used as mourning jewelry, ancients believed black tourmalines to be stones that protected against negativity and strengthened the heart.
Tourmalines are piezoelectric, meaning they can generate electrical charges when heated, compressed or vibrated. They then become polarized crystalline magnets and can attract light objects. The Dutch knew about this effect and used heated tourmalines to extract ashes from their pipes. The stones were even favorite toys of Dutch children before their gem quality was established. Because the gem's electrical charges attract dust and small materials, some believe that wearing pink tourmalines will attract love and green ones will attract success.
Tourmaline has often been called the "muses' stone" because it is believed that its imaginative colors contain inspirational powers that grant enlightenment, enable creativity and express an artist's mood. Due to the stones' energetic conductivity and vast array of elements, they are thought to have powerful healing abilities and protect against many dangers. Tourmaline is supposed to be an especially powerful influence on love and friendship, fostering compassion and cool headedness. It is considered the traditional gift to give couples celebrating their 8th wedding anniversary.
Ever since the ancient days, the gem has been attributed with magical powers. Today, specific colors of tourmaline are thought to hold individualized powers. Black is believed to bring luck and happiness when rubbed. Green is said to encourage communication and bring success, while blue is a balancer that stimulates other tourmalines' effectiveness. Watermelon tourmaline is believed to increase perception and creativity, while balancing passivity and aggressiveness. Pink is thought to promote peace, increase spiritual understanding and bring forth love and friendship.
Zircon often suffers for its name’s similarity to “cubic zirconia,” the simulated diamond. The stone zircon, however, is actually a beautiful natural gemstone. It is named from the Persian word “zargun,” meaning “gold-colored.” This is despite the fact that it comes in a wide range of rainbow colors . The majority of zircons are brown or yellow-brown, while pure red and green are the most valuable colors. The yellow-red to reddish-brown variety is called “hyacinth.”
For many years, the most popular type of zircon was the colorless variety. More than any other natural stone, colorless zircons produce a brilliant sparkle similar to diamonds . The most popular color today tends to be the bright pastel blue variety. Sometimes called “starlite,” blue zircon has recently become considered an alternative birthstone for December.
Zircon is one of the heaviest gemstones, meaning that it will look smaller than other varieties of the same weight. It ranks a hardness between 6.5-7.5 on the Mohs Scale and is mined in Cambodia, Sri Lanka, Thailand, Myanmar and Australia.
Travelers during the 11th century wore zircon amulets for protection and to encourage welcome greetings on their journeys. In the Middle Ages, the stone was said to bring wisdom and prosperity to its owner. Hindu mythology even mentions the gem when referencing the Kalpa Tree, which was a glowing tree covered with gemstone fruit and leaves of zircon.
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 century 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 demantoid s 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 and dispelling anger. 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.
Earring Back Types
Butterfly Back: A double looped piece resembling a butterfly that fits over a post. Variations on this design are called push back clasps. The basic post and butterfly back are usually used for stud earrings and lighter weight drop earrings.
Hinged Snap Backs: This clasp features a hinged post that snaps into a groove on the back of the earring. It is commonly found on hoops. Sometimes the hinged post is curved to provide more room to fit around the ear, sometimes called a saddleback.
Hook Backs: This earring backing is simply a long, bent post that fits through the piercing. Hooks have several variations, most notably the shepherd's hook and the French hook. While thin wire hooks reduce the weight of long earrings, making them more comfortable, they aren't as secure as other clasp styles.
Lever Back: A hinged lever snaps shut against the curved post to form a closed loop around the ear lobe. This clasp is very secure and good for large or medium sized styles that drop just below the ear.
Omega: Also called French clips, this clasp has a straight post and a looped lever. The hinged lever closes around the post and is held against the ear with pressure. The omega clasp is the most secure clasp, especially for the larger, heavier earrings.
Screw back: This backing is a slight variation of the standard post and butterfly nut back. Instead of pushing on the back, the nut twists onto the threaded post. A screw back post design is often preferred for expensive diamond stud earrings that require increased security.
