# BRA-6, $38.00 Sold!
Dims: 1.8x1.2x0.7" (4.5x3.0x1.7 cm) .... Wt: 0.7 oz. (20.2g) .... Loc: Linopolis, Minas Gerais, Brazil
This arrowhead shaped specimen of brazilianite is a greenish-yellow color, typical for the species. It is transparent, but a myriad of internal fractures makes it impossible to see more than a few millimeters into the crystal. The front crystal faces are natural and clean, and at first I thought that the rear faces were formed by cleavage or fracture, but after close examination, I believe that the faces are natural growth faces, even though they are rough.
# BRA-5, $29.00 Sold!
Dims: 1.0 x 0.9 x 0.6" (2.6 x 2.2 x 1.5 cm) .... Wt: 0.2 oz. (5 g) .... Loc: Mendes Pimental, Minas Gerais, Brazil
This thumbnail piece consists of a cluster of at least 6 separate Brazilianite crystals that rest on an albite base. The crystals are generally in good condition, though two of them are broken and incomplete. The largest intact crystal measures 0.7" (1.9 cm) and, like all the others, has excellent monoclinic bladed form. All likewise have the standard green-yellow color and vitreous luster and are transparent and moderately clear due to internal fracturing.
# BRA-4, $60.00 Sold!
Dims: 1.0 x 1.0 x 0.6" (2.5 x 2.5 x 1.6 cm) .... Wt: 0.2 oz. (7 g) .... Loc: Mendes Pimental, Minas Gerais, Brazil
A cluster of four separate and distinct Brazilianite crystals rests on the albite base of this thumbnail piece. Only two of these crystals are intact and complete, and the largest has dimensions of 1.0 x 0.5 x 0.3" (2.5 x 1.3 x 0.8 cm); the smaller one is about 75% of the size of the larger. Both are in excellent condition, showing no appreciable damage, and both have excellent monoclinic bladed form. Their color is the standard yellow-green and their luster is vitreous, and both are transparent and dimly to moderately clear due to intense internal fracturing.
# BRA-3, $55.00 Sold!
Dims: 1.9" x 1.9" x 1.3" (4.8 x 4.8 x 3.3 cm) .... Wt: 1.67 oz. (47.5 g) .... Loc: Linopolis, Divinodas Laranjeires, Minas Gerais, Brazil
This specimen shows a lot of damage, as most of the Brazilianite crystals therein are either heavily intergrown, broken, or both. There are several, however that are intact and undamaged, though they tend to be quite small. The largest discernable crystal has dimensions of 0.6 x 0.4 x 0.2" (1.5 x 1.0 x 0.5 cm); it is missing a substantial part of its termination, but its monoclinic prismatic form is evident. All of these crystals show a pale yellow color that is subtly tinged with green and have a bright, vitreous luster. They are transparent and moderately clear, though even the intact crystals show noticeable internal fracturing. Along with the tangle of Brazilianites are a small piece of what looks like a white feldspar, and an intact "book" of muscovite of impressive quality; it shows no damage, and though its shape is rounded and warped in some spots, it is quite attractive. There is no host rock present.
