Pyromorphite
stock #0805-JM-445
Kamioka Mine, Hida-shi, Gifu Prefecture, Chuba Region,
Honshu Island, Japan
6.3 x 3.9 x 2 CM (cabinet)
price: $1250
pre Tucson 2015 update

A rich crystallized plate of uncommon Japanese Pyromorphite, ex John Marshall collection. John obtained this specimen about 1962 as he was building his famed suite of worldwide Pyros. It is likely much older. These are rare to see on the market, and quite prized when available. The crystal coverage is dense over a 5 CM area, with a nice olive green color. Maximum size of individual crystals is 6 mm, the average perhaps 3-4mm with moderate luster. The backside of the specimen is also covered with crystals, tho not as dense and with smaller individuals so it is the back. A skilled trimmer could make 2 specimens if wanted. The condition of the front side crystals is mostly good but magnification shows a few broken crystals. Despite this it is a fine display piece from an uncommon locale.
Wulfenite with Fluorite and Calcite
stock #Alec 29-63
Red Cloud Mine, Silver District, Trigo Mts, La Paz County
Arizona, United States
5.2 x 3.4 x 3.2 CM (small cabinet/ large miniature)
price: $420
pre Tucson 2015 update

A nice, sharp, complete Wulfenite perched on a contrasting matrix that includes pale purple Fluorite in small spheres. An unusual combination from the famed Red Cloud Mine, this is quite esthetic and eyecatching. The main Wulfenite is 1.3 CM across and deep orange-red. Displays well, no eye visible damage but some very tiny contacts noted at 10X magnification. Good value.
Galena with epitaxial octahedrons on cubic crystal.
stock #A7-029-107
Pitcher, Ottawa County
Oklahoma, United States
4.8 x 3.3 x 2.8 CM (miniature)
price: $240
pre Tucson 2015 update

From the classic Tri-state locale of Pitcher, this is an esthetic, textbook perfect specimen with incredible form. The elongated cube main crystal has a fine gunmetal luster and color, but it is wonderfully decorated with oriented octahedral Galenas that are perfectly aligned across the faces. The geometry and architecture of this specimen is incredible, it is in excellent condition. This comes from early mining prior to the 1930's, and is far better in person.
Conichalcite with Hemimorphite
stock #1139-JM-4105
Bristol Silver Mines, Lincoln County
Nevada, United States
11 x 8.3 x 5 CM (cabinet)
price: $300
pre Tucson 2015 update

A very unusual and significant US specimen, a sizable cabinet piece with excellent color and form from this little known locale. Ex John Marshall collection, John's collection catalog notes that he has only ever seen 3 specimens from this location, this being the best. The deep green Conichalcite is composed of small balls with bright "wet" luster that are offset on the lighter colored Hemimorphite. With magnification it seems there may also be some Aurichalcite on this specimen but that is not confirmed. A fine display piece that is as good as any US Conichalcite from anyplace. Better in person.
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.
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.
Beryl V. Aquamarine hollow crystal on Clevelandite w. Hydroxl-herderite
stock #0811-JM-1450
Dassu, Braldu 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.
SOLD Elbaite- large dark green Tourmaline with
stock #SOLD 10.1-450
Barra do 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.
