TALMESSITE

A specimen very rich in talmessite crystals, an uncommon calcium–magnesium arsenate that forms a series with wendwilsonite. In this piece, numerous aggregates of tabular crystals can be seen, arranged in fan-like groups that, in turn, cluster into globular formations. The colour of this mineral species can vary from colourless to orange or pink, as in this case. The talmessite appears coating a matrix of quartz crystals, over which its tones and crystal habits stand out clearly.
