A very rich and fine specimen of sparkly, gemmy arsenates from the Bou Azzer District. The light rose-red wendwilsonite crystals are the rare magnesium analogue of roselite and Bou Azzer is the Co-type Locality with the Sterling Mine of New Jersey. The glassy, magenta roselite crystals, the cobalt analogue of wendwilsonite, are a very nice compliment. An excellent example of the species and famous locale. Ex. Wes Parker Collection.
