Garnet

Garnets are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition. Garnets are a fascinating group of gemstones that come in a dazzling array of colors. While many associate garnets with deep reds, they also exist in vibrant greens, oranges, yellows, and even color-changing varieties. Prized for their brilliance and durability, garnets have a long history in jewellery.
