Rare tektite gemstone from the Czech Republic.  Moldavite formed when a meteorite smashed into Earth 14,700,000 years ago.  Moldavite hunters search the woods and fields for the gems after big rainstorms.  Moldavite miners can't wait:  They dig pits with shovels just big enough to fit them and their ladder as the hole gets deeper.  They sift through the mud hoping to find these gorgeous dark green gemstones so you and I can have this fabulous jewelry.
