An exceptional and rarely-seen Petalite crystal from Pakistan. The large 7 cm crystal is translucent to gemmy, and has classic etched faces. The shape of the crystal is very much like that of a ship's hull. That being said, both the bottom and the top of the crystal are flat and very lustrous. Also, there is a distinct plane running from tip to tip down the center that looks for all the world like a twinning plane. Ex. Charlie Key.
