Elbaite- large dark green Tourmaline with
stock #10.1-450
Barra de Salinas Mining District, Coronel Murta
Minas Gerais, Brazil
9.9 x 2.2 x 2 CM (cabinet)
price: $760
pre Tucson 2015 update

A very lustrous, glassy tourmaline that has zoning of dark-mid green to a nearly black green. It also sports a fibrous "cats eye" type structure best seen near the base. An older Schortmann's Minerals specimen (with label) that dates this back to the 1940's. Classic habit and form from Barra Do Salinas, few of these survived cutting as the cats eyes they show were quite desirable. Very minor chipping is noted with magnification but the overall quality is fine. The complex multiple terminations and deep striations give this a eyecatching quality.
Beryl V. Aquamarine hollow crystal on Clevelandite w. Hydroxl-herderite
stock #0811-JM-1450
Dassu, Shigar Valley, Skardu District, Baltistan
Baltistan, Northern Areas, Pakistan
6.8 x 4.5 x 4.7 CM (cabinet)
price: $200
pre Tucson 2015 update

Unusual habit Aquamarine ex. John Marshall Collection. The main crystal is 3.4 CM across the termination face, with an etched cavity in the center that bells out inside the crystal. The there is also a 2.2 CM Hydroxy-herderite crystal on the back side as a bonus. Good condition and a very nice "oddity" from this prolific region.
Gypsum (v Selenite) prismatic gemmy crystal
stock #Alec-12-565
Fuentes de Ebra, Zaragoza
Aragon, Spain
3.3 x 2 x 1.8 (small miniature/ large thumbnail (toenail))
price: $125
pre Tucson 2015 update

Glass clear and textbook sharp this is a small but super clean specimen from the alabaster quarries of Fuentes de Ebra. These are very fragile and so there are few that survive in such perfect condition. Since these are so distinctive they are found in many top collection but rarely are for sale in this quality. Unlike many this is not a twined crystal but a single prism that is optically clear.
Quartz, var. Agate, Pseudo after Aragonite crystals
stock #Alec-10-608
Las Plumas, Martires Dept.
Chubut, Argentina
6.9 x 4.8 x 4.3 CM (cabinet)
price: $250
pre Tucson 2015 update

Distinctive hexagonal sixling aragonite form are fully pseudomorphed by quartz in this esthetic arrangement. A few small broken crystals serve to show the internal agate form that has replaced the Aragonite. A classic and complete true Pseudomorph, this material is no longer available, it has been found sporadically for several decades. This has the most sharp detail and best crystal arrangement that I have seen.
Amethyst -zoned crystals
stock #13.1-129
Amatitlan, Municipio de Zumpango del Rio
Guerrero, Mexico
4.1 x 2.1 1.9 CM (miniature)
price: $285
pre Tucson 2015 update

An attractive miniature showing the distinctive habit of Guerrero Amethyst. This shows both the classic esthetic arrangement and shape of crystals with the zoning that sets these apart from all other Amethyst. In good condition, there is some chipping to be found with magnification so this is not for the perfectionist. Far better than average and much more affordable than larger pieces. Vintage about 1955.
Pyromorphite - Classic Locale, ex Frank Wright Collection
stock #14.1-067
Wheatley Mines, Pheonixville
Pennsylvania, United States
5 x 3.5 x 1.6 CM (miniature)
price: $325
pre Tucson 2015 update

An olive green crystal plate from this venerable old locale that is densely covered with free standing crystals. The condition is overall excellent but with magnification some very small damage can be found, mostly at the edges where this was removed. The Pyromorphites themselves show several habits including hoppered and tapered terminations. This specimen is a little lighter in hue than is most Pheonixville specimens, but it has the classic luster that is distinctive.
Sphalerite (red-black crystals) on Calcite with Fluorite
stock #A7-019-831
Elmwood Mine, Carthage
Tennessee, United States
8.4 x 6 x 3.1 CM (cabinet)
price: $420
pre Tucson 2015 update

An attractive Sphalerite crystal cluster that has flower-like form is perched on a contrasting matrix. The color looks black at first glance but with strong lighting it is a translucent dark red-brown (rubyjack) color. The luster is extra glassy bright and the quality is fine. The front of the specimen is in excellent shape damage wise, the back and one edge is contacted which is not seen from the display side. Sphalerite specimens from Elmwood are common, but esthetic specimens of this caliber are quite rare to find. A lot of display impact for the size.
Sphalerite with Dolomite, Galena
stock #Alec-18-034
Huaron Mines, Huaron Mining District, San jose de Huayllay District
Pasco Department, Peru
5.9 x 5.5 x 3.2 CM (cabinet)
price: $380
pre Tucson 2015 update

Dark orange Sphalerite in well formed crystals perched on a contrasting Dolomite in an esthetic arrangement. This comes from a small find in the late 70's at Huaron that was unique. The crystals are translucent and glow with backlighting, but in normal light this still displays very well as seen here. A good example of this old find that is very rare on the market.
