Moldavite is called the crystal from outer space. The bottle green to very dark green stone is thought to have been formed during a meteorite shower in the Moldau Valley of Czechoslovakia about 20 million years ago. The great impact of the shower likely melted meteorite with terrestrial minerals to form this unique stone.

Derived from "tapaz," the Sanskrit word for fire, topaz is one of the most brilliant cut gemstones in existence. Topaz comes in a variety of colors from yellow to blue, and deeper blues and pinks are often created by heat-treating stones. Brazil is the world's top exporter of topaz.
