Description

Sculptural, partly hoppered (!) crystal of tincalconite, progressively pseudomorphing borax. The crystal is very sharp, basically a floater, as base contact point is minimal. In excellent conditions, it is only slightly powdery, hence I suggest to keep it in a protected environment.

This is by far one of the largest single crystals I have ever had for sale and it is easily dated back to the 50s-60s.
