Abstract

SiO - Mohs Hardness: 6 – 7. Chalcedony is a very important ornamental stone. The varieties Agate, Chrysoprase, Carnelian, Sard, Tiger's Eye, Bloodstone, Jasper, and Moss Agate are all carved into cabochons and beads, making fine yet inexpensive gems. The apple-green variety, Chrysoprase, has a distinct color and commands a higher price than the other varieties. Light blue Chalcedony has also become popular as a gemstone.
