21hhdf.774 ((ARSENOPYRITE with EXPITAXAL PYRITE, QUARTZ)), $60 MINIMUM BID, Santa Eulalia, Chihuahua, Mexico, 2 x 1.5 x 1.5 cm, Thumbnail | |
Here is a pair of Arsenopyrite crystals. larger is stands out and and the other at 90 degrees at the lower half of the larger crystal. Complete crystals which are highly lustrous with a lustrous expitaxal Pyrite. Almost looks like the Pyrite is replacing the Arsenopyrite. I do not think its a psuedomorph but it is the only one I have seen like this. Picture does not do it justice. ex Don Fratto collection. |
