Moldavite - knowledge base, jewelry
Properties of moldavite, physiological effects, zodiac signs and moldavite jewelry.
Moldavite takes its name from the river Moldva in the Czech Republic, where it is found.
It belongs to the group of tektites. They are formed by meteorite impacts (the meteorite probably melts the surrounding rocks on impact, and when it cools down in flight it takes on a strange shape). Moldavite has an uneven surface with a glassy sheen. They are usually translucent and come in a variety of colours. They usually contain characteristic round or elongated bubbles or vortex-shaped inclusions. Moldavite crystals are rarely heavier than 20 g, with the heaviest moldavite crystal found so far being 265.5 g.
