Rich and beautiful specimen of glass opal – hyalite from Valeč. Very nice specimen of colorless amorphous aggregates of hyalite, which form a large crown on a flat sample of volcanic rock; the specimen has a cut base!
- You cannot add that amount of "Arsenic, proustite" to the cart because there is not enough stock ( remaining).
