Ex. John S. White
According to MINDAT, "This mineral, fully hydrated copper sulphate, is very rare. " This is a LARGE specimen smothered in crystallized boothite, composed of stacks and sprays of agglomerated microcrystals. It is also very attractive as a display specimen. I have never had another example of this species for sale. Acquired by John White in 1969
