A pretty, small cluster of some sharp, bipyramidal red tancaite-(Ce) crystals, mounted on the top of a pin with black tac (therefore removable if you want). As you can see from the photos, the sample is well enjoyable under the microscope. Tancaite-(Ce) is a very rare mineral, the first and at present the unique of molybdenum and REE , its type locality is the small mine of Su Seinargiu, Sardinia.  Very very nice and very hard to find a loose floater like that!
