A gemmy light blue-gray crystal measuring 5-cm, next to a 2.5-cm crystal, both terminated in the center of the display face -- on a bed of muscovite crystals. If you look at the side of this specimen, where it was removed from the pocket, you can see that the 5-cm crystal actually is wide and flat, extending back underneath the muscovite for 7 centimeters! This large and showy specimen was sawn flat on the bottom and back to remove it from the matrix and give it a natural base for display. 15.0 x 11.3 x 9.6cm
