Measurements: 83 x 35 x 28 mm
Description: The largest crystal, with two terminations, is mostly clear with bits of smoky and amethyst colouring, flaws and gas inclusions. The second largest crystal had at some stage broken, and then rehealed spontaneously at a later stage, at an unusual angle (bottom two images on left).
The terminations appear to be perfect. The only notable damage is where the specimen became detached from other minerals at the bottom and lower end on the side where the piece of calcite is attached.
This specimen comes from a 2015 find.
