Copper Pseudomorph After Aragonite
Miniature, 3.9 x 3.3 x 2.1 cm
Corocoro, Bolivia
Ex. Richard Hauck
Although its original external form is still obvious as being aragonite, it is very evident that the aragonite has been totally replaced by copper. This is a neat, unusual, specimen! These classic copper pseudos are seldom seen today on the market and to me represent one of the most interesting pseudos of all out there, in that such a common carbonate as aragonite has been replaced by a native element.
