Topaz is a rare silicate mineral that is also considered to be a semi-precious gemstone. It occurs naturally in a wide range of colors, but most natural topaz is colorless to light-yellow. Topaz has a hardness of 8 on the Mohs hardness scale making diamonds, corundum, and chrysoberyl the only commonly known minerals that are harder.

It primarily forms crystals within veins and voids of volcanic rocks. The crystals grow during the later stages of magma cooling while degassing releases the fluorine required for crystal formation. Topaz crystals are either mined from inside these voids in pegmatites or collected after it has eroded out of the rock.

Most topaz is light sensitive and can fade in color if exposed to direct sunlight for too long.
