Gorgeous and lustrous, blue-green cuprian adamite botryoids aesthetically line a vug in contrasting gossan matrix. This very showy specimen is from a recent, 2006, and small find at the Brenner Mine at Dalnegorsk. The Brenner Mine is the oldest upper workings of the Verchniy Mine. The fine color is reminiscent of classic kelly-blue smithsonite, excepting the crystal form. Seldom on the market. From an old stash.
