One of the finest Erythrite specimens I have ever personally seen, this is magnificent example of this rare Cobalt mineral, featuring aesthetic rosette-like sprays of undamaged bright magenta-red crystals to nearly 2.7 cm. (!) on ore matrix. Fantastic and very pretty example of an uncommon mineral in a truly uncommon quality. One clean/invisible repair to part of the matrix (does not affect any of the crystals).
