What is Moldavite primarily classified as?

Moldavite is primarily classified as natural glass because it is formed from the intense heat and pressure generated by the impact of a meteorite striking the Earth. This unique origin differentiates it from other gemstones that are typically mined from the earth or formed through geological processes over long periods.

Moldavite is specifically categorized as a tektite, a type of glass that results from the alloy of silica with other elements during a meteor impact. This natural glass can display a range of colors and textures, which are a result of its formation process. Unlike fossilized wood or enhanced gemstones, which involve biological processes or treatments to improve appearance, Moldavite's identity as natural glass is tied directly to its extraterrestrial origin and formation mechanism. Additionally, although some gemstones are derived from mineral crystals, Moldavite's classification as a glass makes it distinct among other materials.
