What is Moldavite?

Moldavite is natural glass formed in association with an ancient impact event and occurs most famously in central Europe. Typical material appears in olive to bottle green shades, and is commonly described as natural impact glass (tektite). The Mohs hardness for this material is approximately 5–5.5; hardness refers to resistance to scratching, not to breaking, cleavage or sensitivity to chemicals. Modern market imitations are widespread; bubbles and surface textures do not alone prove authenticity. Typical geological or commercial source regions include Czech Republic; this does not establish the provenance of an individual gem. Protect from impacts and scratches, and clean with a soft cloth and mild soap. Ask for confirmation of identity, natural or lab-created status, and any treatments when choosing an individual stone.
