This quartz crystal got an amazing quality and transparency.
There are a couple of nicks in the top, and a smaller damage in the bottom.
You will see a few inner cracks in the bottom. In the top and middle of the crystal it is 100% transparent (without inner cracks), which is very rare with crystals on this size.
Unfortunately my father had no label on this one, so I do not know its location.
