- Ghom Salt Dome, Iran
- Small Cabinet, 6.1 x 5.0 x 3.0 cm
- Ex. Martin Zinn
A very rare sulfate, that is apparently stable, and comes at a surprising quality level form these vast salt deposits in Iran. This piece, with numerous crystals to over 1 cm, is (i am told) of a superior quality. I have simply never seen another of any quality, for sale.
