Prehistoric Meteoritic Impact Glass - Go to the link and read a very interesting story about this rock!

Libyan Desert Glass was formed 29 million years ago, very likely when an asteroid or comet hit the surface of the earth like a huge atomic bomb, unleashing enough destructive force to liquefy the rocks, sand and dirt at ground zero. It is a natural glass composed of nearly pure silica (98%), the purest natural glass in the world. A carved scarab on Tutankhamun’s jeweled breastplates is Libyan Desert Glass.

Amber Amber is technically not a gemstone or mineral, but a fossilized sap from prehistoric trees that has aged over the course of millions of years. Amber is usually thought of as yellow golden in hue, but amber also can be found in shades of milky white, red-orange, green, black and even (very rarely) violet.

Opalized Belemnite fossil. More than a 100 million years ago, the central part of Australia was an inland sea, thriving with marine life. Shells, bones or cartilage formed cavities in the sandstone or the sea floor. These cavities were then filled with silica and formed the beautiful opalized belemnite pipes, shells and prehistoric fossils that we marvel at today. Belemnites (or belemnoids) are an extinct group of marine cephalopod, very similar in ma...

Opal Pseudomorphs are created by the deposition of opal in casts of fossil bone, teeth, shell, belemnoids (ancient relatives of cuttlefish), crinoids (sea lillies), wood, fir cones and even skeletons of large prehistoric animals. Many of these fossilized forms contain exceptional quality noble opal.
