Divinésia, Minas Gerais, Brazil

3.4 x 1.4 x 1.2 cm. 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 ...

3.4 x 2.4 x 1.1 cm. A fine, old-time samarskite (now samarskite-(Y)) from the lesser known locality at Divinesia, which produced several fine examples of the species years ago. A parallel growth group of sharp, well-formed, blocky, "sword"-shaped crystals of samarskite-(Y) with a reddish-grey hue free of matrix. No damage, though some of the ...

4.0 x 2.9 x 1.5 cm. A large, crude but terminated, mostly complete crystal of euxenite-(Y), a rare yttrium niobate, that exhibits a nearly black, sub-metallic interior and with a white to yellowish surface alteration coating. The mineral is undoubtedly metamict from contained actinide elements. Euxenite generally occurs in pegmatites of a unique ...

Yellow ferrimolybdite crystals in the matrix.

Samarskite crystal.

Samarskite is an uncommon, rare-earth oxide found in pegmatites, and this excellent example is from the less well-known Divino de Uba pegmatite of Brazil. The form of the orthorhombic, parallel-growth samarskite is typical for this area, and being in combination with the columbite is a rare, but signature, occurrence here. Accompanied by a ...

Parallel grouping of samarskite-(Y) crystals with the typical coating found on weathered-out crystals, with uncoated, black, epitaxial columbite-(Fe) crystals (as labeled). Parallel crystallizations of these two minerals are common at the Spinelli prospect. Eric Quinter specimen U/Th 0015.

Here is a really interesting specimen...for those who appreciate rarity within rarity: it is a group of Columbite-(Fe) crystals that have as a "sandwich" a Samarskite-(Y) crystal. It is a magnificent example of a parallel association of iron oxides, niobium and rare earths, quite characteristic of the area now called Divinesia (once known as ...
