A: Glass is an amorphous form of silica (with various percentages of additives) that has been used as a gemstone for millennia.
Glass for gemstones is man-made, formed by fusing silica sand with various additives at temperatures of 1000+°C.
Natural glasses include obsidian, which is is a rapidly quenched lava, and closer to pure silica glasses, such as libyan desert glass.A unique man-made glass, although not often used in gems for obious reasons, is trinitite, a mildly radioactive glass formed from the fusing of sand by the detonation of the first atomic bomb in 1945.
