Description

Very rare yellow kleinite crystals - known only from three other localities worldwide. Beige kuzminite (only two other localities known!) and other minerals on this little specimen.

All Moschellandsberg specimens in this auction are from the Schlabach collection, all found 1980. They have been analyzed, but printouts of the original analysis cannot be provided. If neccessary I can have new analysis made, which the buyer would have to pay.

Unfortunately I don't have the means to do micro-pictures.
