Considered a blend of heaven and earth, tektites are fragments of natural glass formed from meteorite impacts with our planet. Tektites are assigned names based on their location. Thus, moldavite, named after the Moldau river in the Czech Republic, is found in that country. The intense pressure and temperatures present during its formation preserve tiny gaseous bubbles in many moldavite gems.

Moldavite is the result of the impact of a meteor with earth... about 12 million years ago! For this reason, some people consider it to be a blend of heaven and earth. Moldavite is found primarily in one place in the world (Czech Republic) and exhibits a deep, rich, dark green. It's a tektite - fragmented natural-glass formed when the meteorite struck. We love it for its unique forest-green color which shows whispers of brown undertones.
