Beryl var. Goshenite - highly etched crystal
stock #16.1-333
Urucum Mine, Galileia
Minas Gerais, Brazil
5.6 x 3.5 x 1.8 CM (small cabinet/ large miniature)
price: $340
Spring 2020

Perfect, gem clear and absolutely colorless, this looks just like ice. A natural sculpture of an etched Beryl crystal, this is also a complete floater, every surface is complexly faceted, etched and undamaged. Not many minerals can exhibit this degree of sculptural etching, however we do see this with Beryl from a few finds and these can be incredible in person. True colorless Beryl (Goshenite) is also quite uncommon, this specimen is displayable from any side or angle, the larger faces are smoothly curved yet striated and it is fully transparent with no inclusions, veils or cracks. Choice.
Kyanite -gemmy crystals on Quartz
stock #16.1-630
Capelinha, Jequitinhouha Valley
Minas Gerais, Brazil
6.7 x 3.8 x 3.3 CM (cabinet)
price: $750
Spring 2020

This is not at all a typical Kyanite, the crystals are vivid blue, gem clear and are sharply terminated. Well presented on a massive Quartz matrix, these crystals are perfectly exposed and brilliant in person. With backlighting this glows an intense blue hue. Some zoning is noted with the "stripes" of clear and deep blue running along the C axis of the crystals. Huge amounts of Kyanite come out of Brazil but super gem grade display pieces are very rare, this is a superb example with a lot of display impact. Better in person.
Elbaite with Lepidolite
stock #15.1-1008-(CN520)
Virgem do Lapa
Minas Gerais, Brazil
6.8 x 1.6 x 1.4 CM (cabinet)
price: $690
Spring 2020

A doubly terminated gem Elbaite crystal is partly wrapped in a "cloak" of Lepidolite. The Tourmaline color is a mix of green and blue hues, it is zoned but not sharply, the colors grade together gradually. In excellent condition there is no naked eye visible damage or chipping on the Elbaite. With strong magnification two very slight nicks (under 0.5mm) can be found, this is essentially perfect. The "bottom" termination is a flat basal type while the top is a stacked series of angled faces. Especially pretty with backlight, the association with the sparkling Lepidolite makes a nice contrast. Ex Charles M. Noll collection, 18.7 grams
Beryl variety Aquamarine with internal open tubes
stock #19.1-428
Padre Paraiso
Minas Gerais, Brazil
5 x 1.2 x .8 CM (miniature)
price: $280
Spring 2020

Gem clear terminated Beryl crystal that has several inner channels or tubes. There is one small tube that opens in the middle of the termination but the others are closed inside the prism. In excellent condition a nice pale green crystal with a termination that has both a tapering form and a flat top. It is incredible how many variations and modifications of Beryl that have been found over the years, and Brazil in particular has been the source of many unique habits.
Elbaite - Indicolite
stock #17.1-549
Barra do Salinas Mining District, Coronel Murta
Minas Gerais, Brazil
4.9 x 3.5 x 3.4 CM (miniature)
price: $1450
Spring 2020

A complex dark Tourmaline crystal that when backlit explodes with an intense deep indigo blue with a zone of green on the edges. From old finds at the remarkable locality of Barra do Salinas which is well known for very colorful and often deeply etched gem crystals. This specimen is the termination of complex prism, the faces are lustrous and the overall weight is 78 Grams, nearly all of good gem grade. There is old edge chipping most of which has been recrystallized, but despite the imperfections the color and luster make this a striking piece. Without any backlighting this is fairly dark and may look like a schorl at first, but when well lit the color is outstanding.
SOLD Topaz -rare purple
stock #SOLD 19.1-806
Ouro Preto
Minas Gerais, Brazil
2 x .9 x .7 CM (thumbnail)
price: $0
Spring 2020

Gemmy thumbnail crystal of imperial Topaz with the very rare pink-purple color. From the classic locality of Ouro Preto which has produced vast amounts of yellow and light orange Topaz over many decades. The purple and pink-purple colors are unique in the world. At Ouro Preto these are very rare and highly sought after, there has not been any new finds of purples in many years. Some similarity is seen with pink Topaz from Katlang, the only other source that ever came close, but the purple color from Ouro Preto is quite different, and treasured as gem rough and especially as specimens. This crystal is fully transparent, complete and lustrous.
Childrenite- Eosphorite (gemmy with unusual color)
stock #19.1-805
Mendez Pimentel
Minas Gerais, Brazil
2.6 x 1.8 x .9 CM (thumbnail)
price: $390
Spring 2020

A super single crystal thumbnail of red-orange Childrenite ex John Buckley Collection. This is translucent to transparent and has internal zoning. From a find many years ago at Mendes Pimental, there were very few found with this unusual color, it is possibly closer to the Eosphorite end of the series though the original testing called this Childrenite, we have not re analyzed this. Complete and well terminated, one part of the termination hosts a zone of tiny doubly terminated Quartz crystals which adds a nice contrast. No matter the specie this is a choice colorful example of both ends of the series.
SOLD Brazilianite -gem crystals, classic locale
stock #SOLD 20-FC-064-(9173)
Conselheiro Pena, Doce Valley
Minas Gerais, Brazil
5.2 x 4.3 x 3.3 CM (small cabinet/large miniature)
price: $0
Spring 2020

A cluster of thick lustrous gem grade Brazilianites from the unusual locality of Conselheiro Pena. In fine condition as seen, only one small edge chip can be found which is not visible on any display angle. The two famed Brazilian localities (Telerio and Corregio Frio both in Linopolis) have a distinctly different look, color and habit from each other and from the less common Conselhiero Pena specimens. This piece has a small amount of matrix but is almost a complete floater. Choice and not often available,
