Scepters of bi-colored Elbaite

In 1994 at the Barra do Salinas Mine they found some Elbaite with interesting features. Thin crystals that started life red and then in their second phase of growth were a very gemmy green. The second phase was also thicker, giving riser to the form that is known as a scepter.
We were able to obtain a lot of these Elbaites that were kept back by a private collector and taken to Tucson, where they were then available for purchase. As you can see the quality is very high and they are certainly beautiful.

TN66F5: In the form of a scepter with a pleasant mix of color, so this is an Elbaite with class. The color is gentle and also intense, especially given the luminous green, which is difficult to describe. A classic beauty.
Barra de Salinas, Coronel Murta, Jequitinhonha, Minas Gerais  Brazil (1994)

Specimen size: 3.5 × 0.8 × 0.6 cm = 1.38” × 0.31” × 0.24”

Sceptered Elbaite
 

TJ47D8: This one takes the first prize in originality. Not only is the main crystal gemmy, in its upper region there is another scepter crystal that crosses the first. All of them are doubly terminated, undamaged and floaters. The best of this unique find.
Barra de Salinas, Coronel Murta, Jequitinhonha, Minas Gerais  Brazil (1994)

Specimen size: 4 × 1.9 × 1.3 cm = 1.57” × 0.75” × 0.51”

Tricolor Elbaite (Tourmaline)

A special find of unusual tricolored Elbaites (Tourmalines) from Brazil. As you can see in the photos the color varies between red-yellow-green. The crystals are totally gemmy, and all of them are very nice. The crystals are not complete at the bottom but their tips are perfect.

TW47M5: The crystal is formed by the six faces of the hexagonal prism and a very acute terminal pyramid. The color shows gradual changes, from the yellow at the base to reddish on the termination, passing through slight orange in the central zone.

MM6I5: Very well defined bright crystals, between translucent and transparent and having an exceptional color. The base is Correianevesite, also crystallized and in some zones of the specimen there are small black crystals of Rockbridgeite. A recent study of the crystals from the Cigana Mine that in 2006 were identified as Reddingite has shown the discovery of the rare species Correianevesite. So, the old Reddingite from Cigana must be renamed as Correianevesite, being Cigana Mine, at Galiléia, the type locality. We’ll send a copy of the analysis of the original “Reddingite” to the buyer.

Hydroxylapatite

Hydroxylapatite with Orthoclase.
 

TH46H4: This Apatite has finally been correctly identified as the species Hydroxylapatite, very less common than Fluorapatite. Crystals, on a matrix of Orthoclase, are flat hexagonal dipyramids with almost no prism faces, a habit that is not often seen with Apatite. Faces of a short prism can be seen on this crystal, a rarity with this material. The Hydroxylapatite is also attractively color zoned.
This specimen's photo has been reviewed and published in the magazine ‘Mineralogical Record’ on page 286 in the volume 40, number 4.
