What is Garnet?
Garnet is a group of silicate minerals that have been used as gemstones and abrasives since ancient times. The name "garnet" comes from the Latin word granatum, meaning "pomegranate," due to its resemblance to the fruit's deep red seeds. While garnet is most commonly associated with a rich red color, it actually comes in a variety of shades, each with its own unique charm.
