Species: Samarskite-(Y), Columbite-(Fe)
Locality: Divinésia, Minas Gerais, Brazil
Dimensions: 10 cm x 5 cm x 4.5 cm

Superb, large, very well-formed group of parallel growth samarskite-(Y) crystals with the typical coating found on weathered-out crystals, with uncoated, black, very sharp epitaxial columbite-(Fe) crystals growing on one side of the samarskite crystal group. This outstanding specimen is truly one of the best I have seen for this classic locality and for the species. Wow! Eric Quinter specimen U/Th 0015, pictured on Mindat.org.
