Sterling Silver

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.

  • Rhodium Plating: Rhodium plating is a complex and laborious process that enhances the luster and beauty and extends the life of silver. A member of the platinum metal group, rhodium is often used as a finishing touch on silver jewelry. It's a shiny silvery metal with a very white and reflective appearance, much like mercury. It's also very hard, so it withstands much wear and tear, resists natural tarnishing and wonderfully mimics the brilliant finish of freshly polished silver.

    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.

  • Avoid exposing sterling silver to direct sunlight and harsh chemicals, including chlorine, ammonia, hair products, perfumes, cosmetics, perspiration and strong jewelry cleaning solutions.
  • Periodically wash sterling silver with mild dish soap and warm water. Rinse well and dry completely with a soft cloth before storing because moisture can cause tarnish.
  • Lightly polish sterling silver frequently with a soft silver-polishing cloth, avoiding abrasive cloths completely.
  • Tarnish is easy to remove when it first forms as a yellowish tint, but becomes more difficult to remove when it becomes brown and black. Remove tarnish with a silver polish cream, avoiding immersing pieces with gemstones in tarnish-removal solutions.
  • Minimize scratches on sterling silver by storing it in its own compartment in your jewelry box or in a cloth pouch. Sterling silver may also be stored in sealed polyethylene bags.


    Topaz:

    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.


    Tourmaline:

    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 nowadays it is called the “Rainbow Gemstone.”

    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 crystals come from a mineral group that usually forms in various combinations of elements. The slightest changes in composition will result in completely different colors. Thus, it is possible that in one naturally grown crystal, there will appear completely different colors. Some will show only slightly shaded color fields, while others will display contrasting colors and defined color zoning. 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. 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.

    A recognizable variety of the gem is simply called, green tourmaline. It comes in a variety of green shades, including leek-green, intense yellow-green, olive-green and brownish-green. Chromium-tourmaline is the trade name for the emerald-green variety. The most rare and highly coveted green hues are the blue-green stones often called African tourmalines and the bottle-green gems referred to as Brazilian tourmalines.

    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 spectacular color is due to the presence of a small amount of copper. A study by the German Foundation for Gemstone Research recently also discovered a surprisingly high content of gold in the stones. While the average gold content of the Earth’s crust is 0.007 parts per million, Paraiba tourmalines contain a remarkable 8.6 parts per million. So if they were not so breathtaking, the gems might be in danger of being crushed to acquire their gold.

    Paraiba tourmalines are mined near a village called Sao Jose de Batalha. In 1989, the miners discovered a new vein of gem-quality stones with extraordinarily bright shades of blue and green. Hand-excavated shafts and tunnels are up to 60 meters deep and the tourmaline is found only in pencil-thin veins. Because of the difficulty in mining, supply will always be limited and Pariaba tourmalines will always be rare and expensive. Dealers all over the world are competing for the Paraiba tourmaline, which means that it can command retail prices more than $20,000 per carat.

    In the year 2000, electric yellow tourmalines were found in Malawi in East Africa. With a clear and pure color, they were deemed “canary tourmalines”. 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. Yellow tourmalines are considered to be the only gemstones that have a fine scent. This is because their 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, who originally brought the stone to Europe, 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 strengthen the immune system and bring luck and happiness when rubbed. Green tourmaline 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.
