Corundum (Var: Ruby)
Thumbnail, 2.7 x 2.7 x 2.1 cm
Mogok, Sagaing District, Mandalay Division, Burma (Myanmar)

It is difficult to find a Ruby crystal this large, let alone one that has such good color and luster AS WELL AS sharp faces. The pics can only hint at how good the clarity is. It is 3-dimensaional and complete all around (though contacted on back face) and displays phenomenally with a burst of color in a case. Much better in person! 2.7 x 2.7 x 2.1 cm
