Description

You are bidding on what is probably the best known specimen of austinite from the Centennial Eureka mine collected by Martin Jensen in 1993. The specimen hosts two vugs with large, pale green clusters of austinite crystals with epitaxial, darker green calcian duftite on the terminations. Really aesthetic example and very photogenic! Large for any austinite crystals!
