OK - obviously I priced this one way way too high. You can tell by all the photos I took, it obviously impressed me. But 225?.......try this price.

This is in every regard one of the finest Leucophosphite specimens you may ever run across. Of course there are better, but not on the market. Although small (3cm), it is loaded with purplish to sherry colored, gemmy and lustrous leucophosphite crystals. The largest crystal is 5mm. In association are yellow Jahnsite crystals, Hureaulite, and a green fibrous mineral, which is probably dufrenite, beraunite, or rockbridgeite.
