Czech Republic Moldavite Average 10.00ct 18x13mm Rectangular Cushion. Gemstone Mined In Czech Republic And Cut In China.<br/><br/>One of the greatest mysteries of our time surrounds the rich olive gemstone, moldavite. Moldavite is a form of tektite. Derived from the Greek word tektos, "to melt," tektite is a naturally occurring glass believed to have extraterrestrial origins. Moldavite is thought to the creation of a meteorite that fell to the earth 15-20 million years ago. The surface of the meteorite fused and melted away upon entering the Earth's atmosphere, scattering the material along the Moldau River in the Czech Republic. The only "celestial" gemstone known to man, moldavite has been associated with the stone of the Holy Grail. It is said to have fallen from Satan's crown as he fell from heaven. Celebrate the mystery of the only celestial gemstone known to man...Moldavite...a brilliant cosmic creation!
