Adamite

Reference: 786

This adamite specimen was from the one-off find of rare purple coloured crystals in the 1980's.  Two cavities in the limonitic rock contain sharp purple, bi-coloured and clear adamite crystals.  There is also a little calcite and  small areas of yellow crystals that  from a visual inspection appears to be arsenbrackebuschite.  Weak green fluorescence in SW UV light.   Ex.
