Arthurite is a very rare mineral, always found as micro-size crystals in only a handful of locations around the world. Originally identified in the 1960's, the 'type' locality is in Cornwall, England.
This specimen is from a small batch collected around 40 years ago from the famous Majuba Hill Mine, Nevada, U.S.A. The crystals are tiny, forming beautiful radiating sprays of grass green.
A magnifying lens or preferably a binocular microscope is required to best appreciate these tiny crystals. An excellent specimen for the macro/micro photography enthusiast.
