Samarskite is an uncommon rare-earth oxide found in pegmatites. This is an excellent and very fine combination specimen from the much less well-known Divino de Uba pegmatite of Brazil. A sharp tan, orthorhombic, parallel-growth samarskite crystal hosts parallel slivers of lustrous, metallic columbite crystals. The samarskite crystal is pristine. Ex, Don Boydston Collection and accompanied by a 1950s-1960s-era Burminco label. A rare and seldom available combination piece from this less common locale.
