Vivianite with Muscovite - rare locale
Cigana Mine, Conelheiro Pena, Doce Valley
5.4 x 3.7 x 2.6 CM (small cabinet/ large miniature)
A choice and rare Brazillian Vivianite from a pegmatite famed for interesting and rare Phosphates. In excellent condition, sizable for the locale and translucent to transparent with a blue green color. The main rosette cluster is over 5 CM tall and the associated Muscovite is significant, this was notable for this one time find in 2007. Pegmatite Vivianites are almost never this large or good since most Vivs are found in Sulfide mines. This discovery was significantly different.
Elbaite - curved, rehealed crystal
Barra do Salinas Mining District, Coronel Murta
3.8 x 3. 2.8 CM (miniature)
An older, fat and substantial Elbaite crystal with a slight curve where it has rehealed. Multi color, 48 grams and with a white fibrous zone at the bend point. There is scattered bits of Clevelandite on a few faces. Good luster and quite sharp complex termination. Better in person too.
A superb large euhedral crystal (7.8 CM tall) dominates a cluster of smaller crystals. Sharp, complete all around and undamaged, this is an incredible example from the famous Linopolis find thirty years ago. Micro crystals of some unidentified Phosphates are also scattered on the specimen and add a little sparkle. Ex Charles Noll collection, the original label call this Herderite as these wwere known then, now understood to be Hydroxlherderite. Most faces show a glassy luster and are transparent in parts. The color of Hydroxylherderite from here can vary widely, this one is mostly light violet-purple but with some zones of greenish, grey and orange. Display well from all sides and the main crystal is textbook quality. These only appear now from old collections like this.
Gem blue-green crystals of Indicolite (Elbaite) standing free from contrasting matrix from early finds at Pederneira. Esthetic arrangement, the Tourmalines have complex multi-pointed terminations that may be recrystallized. One smaller crystal is broken and there is what looks like one small repair, but the larger prisms are fine and undamaged. Nearly all of these have many repairs but this smaller one seems a lot more intact than most. The longest crystal is 3.7 CM. Larger specimens of this color and habit are seen in top collections and sell at the very top of the spectrum. This more modest piece has a strong display character and is an excellent value.
Euclase- colorless gem crystal
Conselheiro Pena, Doce Valley
3 x 1.6 x .7 (small miniature/ large thumbnail (toenail))
Pre Holiday 2017
A perfectly clear, well terminated and sharp Euclase crystal. The faces show fine striations and the top shows a dual tip termination that is unique in our experience. If this was a blue Euclase with this clarity and sizeit would be valued in the 5 figures, but as it is colorless that is clearly not the case! An excellent example that is larger than most from this area of Brazil.
An excellent Apatite crystal cluster from the older finds at the Sapo mine. Far better than most that came out, The color and luster and condition are first rate. These amazing but odd habit Apatites have had many names (Crullers, Snakes, Tubes, Medusas etc) and are fantastic examples of epitaxial growth; These have prisms in a chain or parallel growth that is built around a hollow tube composed of many stacked crystals. A really fine, textbook quality specimen in excellent condition. There is a separate smaller branch growth and very good transparency, color and luster on this. No damage or repairs which is rare in any piece of this size, this is even better in person, to me this is a real mineralogical marvel.
Thumbnail specimen of gemmy Eosphorite crystals in a radiating spray on Quartz matrix. As is sometimes the case there are micro crystals of Zanazzite associated. The condition is excellent and by naked eye perfect. At 20X magnification one small crystal can be found that has some termination damage. Remarkable for this delicate mineral in such long, slender crystals. great value.
Topaz -Classic Imperial type
Antonio Pereira Mine, Ouro Preto
4.1 x 1.5 x 1 CM (miniature)
new june 17
A single Imperial Topaz crystal with traditional color and far above average clarity. In fine condition and mostly gem grade. The color is yellow-orange with a slight hint of red zoning. From the Antonio Pereira area of Ouro Preto, this locality has almost two centuries of history for Topaz finds. This has the most classic and distinctive look for the area but is considerably better than typical quality, form and color.
