Birthstone: January


garnet     Garnet is a group of minerals that have been used for thousands of years as gemstones and abrasives. Noah, it is said, used a garnet lantern to help him steer his ark through the dark night. Garnets are also found in jewelry from early Egyptian, Greek and Roman times. In earlier times, garnets were exchanged as gifts between friends to demonstrate their affection for each other and to insure that they meet again. Many early explorers and travelers liked to carry a garnet with them. It was popular as a talisman and protective stone, it was believed to light up the night and protect its bearer from evil and disaster. Science has taught us that the garnet's proverbial luminosity comes from its high refractive index. Today, it is widely known as the birthstone for January and is also the stone for the Zodiac sign Aquarius. Garnets are most often seen in red, but are available in a wide variety of colors spanning the entire spectrum. The name "garnet" comes from the Latin granatus ("grain"), possibly a reference wherein crystals resemble grains or seeds embedded in the matrix.

Six common varieties of garnet are recognized based on their chemical composition. They are pyrope, almandine or carbuncle, spessartite, grossularite (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite.


garnet  Garnets are available in many colors including red, orange, yellow, green, blue, purple, brown, black, and colorless. The rarest of these is the blue garnet, discovered in the late 1990s in Bekily, Madagascar.It is also found in some parts of the United States, Russia and Turkey. It changes color from blue-green in the daylight to purple in incandescent light, as a result of the relatively high amounts of vanadium (about 1 wt.% V2O3). Other varieties of color-changing garnets exist. In daylight, their color ranges from shades of green, beige, brown, gray, and blue, but in incandescent light, they appear a reddish or purplish/pink color. Because of their color changing quality, this kind of garnet is often mistaken for Alexandrite.

Garnet’s light transmission properties can range from the gemstone-quality transparent specimens to the opaque varieties used for industrial purposes. The mineral’s luster is categorized as vitreous (glass-like) or resinous (amber-like).

Because the chemical composition of garnet varies, the atomic bonds in some varieties are stronger than in others. As a result, the mineral shows a range of hardness on the Mohs Scale of about 6.5 to 7.5. The harder varieties, like almandite, are often used for abrasive purposes.
