1. Legend and History:

The name garnet is said to originally derive from the latin “granatus” which means seed, however, a more efficient meaning is that of the French word (pomme) grenat, meaning pomegranate as most garnet crystals look like the seeds found inside a pomegranate.
Garnet was, for many years, a very sought for semi-precious stone, as jewelry has been found which is dated back to the 6th century B.C. Plinius named all stones which had a reddish color, including garnet, carbunculi.
It is believed that garnet protects it’s wearer from enemies, stimulates the imagination and strengthens the power of love. In addition it is said to cure arthritis, rheumatism, and gaps in the memory.

2. Origin in nature and use:

Garnet is a color changing gemstone, occurring in every color except blue, which may only be seen under specific lighting and circumstances; Most varieties of garnet are named based on their color, for example pyrope garnet received its name from its red almost fire like color.
The main varieties of garnet recognized are, pyrope, almandine, spessartine, grossular, uvarovite, and andradite.
Garnet is mainly used as a gemstone to create beautiful jewelry as it may be found in many colors depending on the variety, thus resembling Alexandrite which is a highly expensive and rare stone.
