The "vermeil" technique of plating sterling silver with gold originated in France in the 1750s. It differs from "gold filled" or "gold plated" in terms of the thickness or thinness of the microns over sterling silver. "Gold filled" pieces have a much thicker layer, between 15 and 45 microns, which is mechanically bonded to the base metal with heat and pressure. Vermeil is a more expensive version of "gold plated". It does not wear off as quickly as gold plating does. However, over time, vermeil wears off and therefore will require re-plating.
Over time your plated items will need to be re-plated. Contact your local jeweler for information on plating services.
Pronounced SAV-OH-RITE, the tsavorite gemstone features an intense green color that ranges from a vivid light hue to a deep, velvety forest shade. It is a member of the garnet family and is often referred to as a green grossularite. Like other garnets, tsavorite is naturally pristine with no treatments and features a strikingly high brilliance.
In 1967, British geologist Campbell R. Brides discovered tsavorite in Tanzania. He found strange, potato-shaped rocks that had breathtakingly beautiful green grains and crystals inside them. In 1971, he discovered the same gemstone vein extended into Kenya, where he could officially start exploiting the occurrence.
Henry Platt, the former president of Tiffany & Co in New York, named the stone after its occurrence near the famous game frontier, Tsavo-National Park. In 1974, Tiffany’s started a special promotion campaign to make tsavorite well known throughout the United States. Campaigns in other countries followed, and tsavorite soon became sought-after everywhere.
Tsavorite is quite rare and can cost several thousand dollars per carat depending on size and quality. Larger stones are exceedingly scarce. Only occasionally is a rough crystal more than 5.00ct found, making tsavorites weighing 2.00ct or more quite valuable. Fortunately, the brilliance and luminosity of these gems are displayed even in smaller sizes. They rank a hardness of 7.5 on the Mohs Scale and enjoy an especially high light-refraction index.
Too new to have folklore of its own, tsavorite is believed to hold the mystical powers of garnet, including protection and healing. Garnets also symbolize loyalty and can be exchanged between friends to ensure they meet again.
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.
Spessartite garnet can be red or blackish brown, but is most commonly available in rich golds, fiery 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 that ranges from that of ripe peaches to the deepest of red-orange sunsets. Signifying energy and joy of life, this stone represents the spirit of individuality and the vibrancy of life. The mandarin garnet has a remarkably high refraction of light, creating an exceptional brilliance that vividly sparkles even in unfavorable light. To bring out the best of the gem’s unique color and brilliance, most are faceted cut to allow for this tremendous sparkle of fire.
The fascinating orange color featured in mandarin garnets plays an important role in Asian arts. Yellow and red, the two colors constituting orange, are not considered opposites in Asia, but rather complements to each other. The color symbolizes the continual change of life throughout the ages. Asian gods and Buddhist monks are often dressed in orange robes and the sky in Asian art is often painted orange.
Mandarin garnets were first found along the Kunene River in Namibia in 1991, embedded in the mica slate where they had been formed millions of years ago. Gemologists discovered the orange-colored stones were in fact variations of the rare spessartite gems and members of the garnet family. At that time, spessartites were fairly rare stones, even for collectors, and had hardly been used for jewelry. Some gemologists called the brilliant orange gemstones "kunene spessartine” according to their occurrence. But quite soon the term “mandarin garnet” spread throughout the international market and the stone made its successful appearance around the world. Popularity increased dramatically and the mine on the Kunene River was soon exploited. Fortunately, in April of 1994, mandarin garnets were discovered in Nigeria. The stones are now available once again in reliable amounts, though top-quality stones are rare and it is difficult to predict how long quantity will remain reliable.
