spinel

Spinel is the birthstone for August. Spinel comes in a wide variety of colors, including red, blue, pink, green, purple, black, gray, and colorless. It has a high Mohs hardness of 7.5 to 8, so it can be enjoyed as everyday jewelry. They are often produced in the same octahedral crystal form as diamonds, and their rounded, soft form gives them a different charm than cut gemstones.
