Did you know that the birthstone for January is Garnet. Garnet is usually thought of as a gemstone but most garnet is mined for industrial uses. A very small number of garnets are pure and flawless enough to be cut as gemstones. The majority of garnet mining is for massive garnet that is crushed and used to make abrasives.
Garnet can come in virtually all colors, however, blue is very rare.
