- Mogok, Sagaing District, Mandalay Division, Burma (Myanmar)
A sharp, translucent, vibrant red thumbnail crystal of ruby from the classic gem mines of Burma, with good crystalline form all around. On the back it is roughly formed from contacts, but complete nevertheless. The piece is, when backlit, gloriously pigeon-blood red in color. Ex. Charlie Key.
