One of the largest specimens of decomposed pegmatite with excellent coverage of lazaraskite crystals. The crystals are present as gemmy, light blue crystals in druses and individual crystals here and there. An excellent specimen! These are the best specimens, in the world, of a limited quantity of this new, very rare mineral, a copper glycolate.
