Quartz (unknown location)
Size: 86x64x53 mm (245,9 gr.)
Here is a very nice and clear quartz, which is damage free in the top.
It has some deformations at the back and at the bottom, but it is all natural the way it has grown. It has no man made damages.
Unfortunately I don't know where this beauty was found, as my father had no label on this one.
