Elbaite -gem clear crystal
stock #18.1-337
Pederniera Claim, Sao Jose da Safira, Doce Valley
Minas Gerais, Brazil
4.2 x .8 x .5 CM (miniature)
price: $220


A clear sharp pair of parallel crystals with slight hint of zoning. Pretty much all gem grade, undamaged and cleanly terminated, this is an affordable and attractive Tourmaline. Since the crystals are rather flat they also transmit light well and are brilliant with any backlight. From finds at the famed Pederneira in 2009.
Kyanite -gem clear crystal
stock #19.1-419
Capelinha
Minas Gerais, Brazil
7.8 x .8 x .3 CM (cabinet)
price: $350


A transparent, glassy single crystal of Kyanite on a small matrix of Quartz. Perfect, complete and very lustrous, this slender crystal comes from a well known Pegmatite and is in remarkable, undamaged condition. With even a weak backlight this glows a rich blue and looks fine from any angle. Kyanite is not a rare mineral but this quality is very uncommon and the proportions are very elegant.
Albite (v. Cleavelandite) - very fine crystals
stock #19.1-283-(3856)
Virgem do Lapa
Minas Gerais, Brazil
7 x 5.8 x 2.7 CM (cabinet)
price: $750


Large, perfect gem clear crystals of Albite with fine textbook form. Ex Rock Currier collection (label # 3856) this shows well the quality of esthetics that Rock was well known for. It is surprising how few collections or even Pegmatite suites we see have a good example of this common Feldspar. These are almost never so esthetic as seen here, this is a striking piece. Albite/ Cleavlandite is a common mineral, but crystals of this size and perfection are just very rare. These crystals are formed as thin hexagonal plates with beveled edges and transverse striations. The whole group is stacked as an epitaxial cluster and shows brilliant glasslike luster. A killer Feldspar, some edges have a dusting of small rosettes of Muscovite that add a nice contrast. Better in person, the individual crystals exceed 5 CM diameter.
Elbaite -unusual form
stock #AX-7-464
Jove Lauriano claim, Linopolis, Divinio das Laranjeiras
Minas Gerais, Brazil
5 x 1.4 x 1.2 CM (miniature)
price: $350


An attractive but unusual Elbaite from a little known locality in Minas Gerais, the Jove Lauriano claim. A tapering crystal with a dark top that spreads out holding many tiny terminations. The shaft of the crystal is a translucent to transparent gemmy deep green, it looks dark at first glance but with backlighting the translucency is very evident. It is common to find transparent tops on dark opaque shafts but this is the reverse of that. No damage, a choice yet atypical Elbaite from the Larry White collection, his number 464, according to his catalog obtained from Tony Thurston in 1983. This locality is not well documented but produced a few nice crystals of this habit long ago.
Elbaite -Rubellite gem crystal
stock #19.1-332
Cruzeiro Mine, Sao Jose de Safira
Minas Gerais, Brazil
3.5 x 1 x .7 CM (small miniature/ large thumbnail (toenail))
price: $800


100 percent gem grade Rubellite, mostly a fine cranberry red color with a lightly yellow zoning at the termination. An older Cruzeiro (Brazil) crystal the color is unusually intense for this locality, this looks similar to some Santa Rosa and Jonas mine crystals yet has a sightly different hue. In excellent condition as seen, with even a little backlighting this glows like red glass. The inside is very clean, this is all facet grade that has avoided the cutting wheel. Choice and better in person. Ex John Buckley collection we think this is a 1970 era piece.
SOLD Kyanite on Quartz
stock #SOLD 19.1-370
Barra do Salinas Mining District, Coronel Murta
Minas Gerais, Brazil
7.8 x 3.7 x 2.5 CM (cabinet)
price: $0


Kyanite crystals with Inky blue color with fine luster. Both crystals on the Quartz matrix are doubly terminated, in great condition with no damage. The larger crystal is a cluster of individual blades that start as a single prism and diverge to many separate sheaves all of which are terminated. Translucent and in a few spots transparent, this is a choice specimen of rich blue color. Kyanite is not a rare mineral but good free standing esthetic crystals are quite scarce.
Spessartine - etched gem crystal
stock #18-AX-7 060-(617)
Pederniera Claim, Sao Jose da Safira, Doce Valley
Minas Gerais, Brazil
3.5 x 1.6 x 1.1 CM (small miniature/ large thumbnail (toenail))
price: $240


A fine, complete floater of naturally etched gem quality Spessartine from an unusual locale. This is an older piece from the famed Pederneira Mine ex. Larry White collection. Similar to the better known Navegadora Spessartine, we have only seen one other example from this locality. Like a modern cityscape or sculpture, this is a fine example of this Garnet habit. Completely translucent to transparent, this is all gem grade, with backlighting (the photos are not backlit) it glows a bright red. In undamaged condition, the geometric etchings and crystal forms are especially sharp on this toenail sized piece.
Lepidolite on Clevlandite
stock #16.1-569
Virgem do Lapa
Minas Gerais, Brazil
5 x 4.1 x 2 CM (miniature)
price: $130


An unusual yet attractive Lepidolite, with color and form that is not at all typical. From the great Pegmatite deposits of Virgem da Lapa, ex. Leoben collection. The Lepidolites are in thin stacks of diverging crystals in clusters having a Orange to Pink color. The matrix is white to colorless Clevelandite in crystals and massive plates. Lepidolite is one of the most attractive Mica minerals often taking many diverse forms and vibrant colors. A choice miniature.
