Almandine and pyrope (and a mix of the two) are the most common types of garnet on the market. Their widespread availability makes them extremely affordable (under $40 a carat). Rhodolite, particularly in its reddish colors, and spessartite in its bright orange red, are more uncommon and therefore more valuable than pyrope and almandine. Spessartite is commonly called Mandarin garnet because in its best color it resembles mandarin oranges.
The most rare and valuable of the garnet species are tsavorite (green grossular) and demantoid (green andradite). Tsavorite--in a lively, strong, bright green color--can command several hundreds of dollars per cart depending on quality and size. Demantoid, considered the queen of garnet, has exceptional brilliance, a higher dispersion than diamond, and a lustrous emerald-green color. A fine demantoid can command several thousands of dollars per carat depending on its size and quality. Demantoids are softer than other garnets, and must be protected from scratches and abrasions.
Demantoids have been very hard to find ever since its exclusive Russian sources dried up. A new Namibian mine has brought them back, but just barely. My Jewelz carries some excellent tsavorite and spessartite samples in our Gem Store. Garnet is one of the few natural gemstones not commonly enhanced to improve its color or clarity. However, garnet is often imitated. The laser industry has perfected some synthetic garnets with crystalline structures similar to the natural gem, but different in chemical composition (it's a non-silicate). Synthetic ruby and spinel are also used as a garnet simulant, as is glass, particularly in inexpensive birthstone jewelry.
Garnets are the birthstone for those born in January
Garnets are the birthstone for those born in January. It is also known as the gemstone for the second anniversary. People tend to think of garnets as being very deep red, but they are actually found in a wide color spectrum. In fact they are found in all colors except blue. Anyone who loves the sun baked colors of late summer will be attracted to this lovely stone.
Garnets are mined worldwide with many mines found in Madagascar, India, Brazil, the US, , and other locations. Unfortunately, not all garnets which are mined are good enough quality to use in jewelry.The word garnet comes from the Latin word granatus. In nature, garnet crystals which were embedded in rock often had the color and shape of pomegranate seeds.
As with all gemstones, garnets have metaphysical connections. During the Middle Ages many believed that garnets would stop bleeding, since most are red. Some early cultures believed that garnets were helpful in preventing and curing infections and blood disorders.
Garnets have been known to Man for thousands of years. It is even said that Noah used a garnet lantern to help him steer the ark through the dark night. Early Egyptian, Greek and Roman times all have evidence of jewelry made from this beautiful gemstone.
