Thin, black, divergent blades of tantalite-(Fe) to 3cm are juxtaposed to a grouping of platy, white, translucent albite (var. cleavelandite) crystals. Minor cassiterite is associated with the tantalite-(Fe). A great association piece from this classic pegmatite locality. A trace amount of chipping to the tantalite blades. Ex. Paulo Matioli collection.
