A fine, old German Torbernite from the Dr. Moritz Lechner collection (his number 7258 is attached), This important collection was begun in the 1850's and the number indicates this was likely added in about 1890. The collection was built from other significant old collections he purchased during those years, so this piece may be even older. The first descriptions of the mineral from here date to the 1770's. Ex John Marshall collection, this piece has a good relatively dense coverage of sharp plates with a nice deep green color. This locale is known for great Mimetites and some rarities, but it is also the type locality for Torbernite.
A very bright, clear and perfect little gem from the great Jeffrey Mine. A fine small miniature / toenail, this could also be trimmed to make a competition thumbnail. The matrix is a mix of clinochlore crystals and small clear grossular that are pale pink or colorless. The main Garnet is cinnamon orange-red, well positioned on the plate and is complete all around. You can see through it perfectly.
Even before this legendary locale closed for good the garnets had become scarce and very expensive when of top quality.This is far better in person and a real bargain for the quality and esthetics.

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
5.2 x 3.4 x 3.2 CM (small cabinet/ large miniature)
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.
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
Bristol Silver Mines, Lincoln County
11 x 8.3 x 5 CM (cabinet)
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.
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.
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.
