Characteristics of garnet
Garnet (carbuncle, anfrax, worm, benisa, becheta or bijazi, leuco garnet, shorlomite, melanite, Ural garnet, andradite, spessartine) is one of the most famous and most beautiful gemstones in the world.
The garnet got its name from the fruit of the same name - pomegranate (which, translated from Latin (“granum”), means “grain”). The garnet was named so because the naturally occurring garnet crystals closely resemble pomegranate seeds.
By the way, a well-known measure of weight - a grain (less than half a percent of a gram), which has been used for precious stones since ancient times, is so named because in the old days they used grains of small fruits.
Previously, all red gemstones were called garnets. And the name "garnet" was first used by the alchemist Albert Magnus in 1270. And only from the beginning of the 19th century, garnets began to mean only certain stones - almandines, andradites, grossulars, pyropes, demantoids, spessartines and uvarovites.
The garnet was known in many places and therefore this gemstone has many different names: carbuncle (from the Latin "carbon" - "coal", since the pomegranate stones very much resembled shimmering coals), anfrax (not only garnets, but also other red stones - ruby, tourmaline, spinel), lal (Russian name), venisa (Persian name), becheta or bijazi (Arabic name) and others.
At the present time, garnet is a transparent red stone (most often almandine and pyrope). But there are also garnets of other colors - leuco garnet (a transparent gem - “leikos” means “white” in Greek), schorlomite and melanite (black garnet), Ural garnet (unusual green color), spessartine (yellow-orange, red-orange garnet). There are no blue garnets.

- pyropes - red and dark red garnets, the color is very thick, which makes the stones seem almost black

Garnet is a very beautiful gemstone and has been used by jewelers since ancient times to make jewelry - rings, pendants, earrings and brooches. One of the most beautiful garnet jewelry is a necklace that the famous composer B. Smetana gave to his wife (now kept in Prague at the B. Smetana Museum) and a garnet set presented to Goethe by Ulrike von Levetsov (the garnet set includes a necklace, two bracelets, buckle, earrings and a ring, in total there are 460 beautiful garnets in the whole set).
