SOLD Proustite Pseudo after Galena- ultra rare vintage
stock #SOLD 0952-JM-18609
Reese River district, Lander County
Nevada, United States
3.2 x 2.7 x 2.2 CM largest (miniature)
price: $0
Spring update

Very rare, exotic and just plain unusual, 3 specimens of Proustite that have replaced Galena crystals. Ex Philadelphia Academy of Science, via ED Drown, later in the John Marshall collection, this is a 19th century find of historic and mineralogical interest. The Proustite or ruby Silver is still showing a good red hue and the replacement of the Galena seems to be complete. I can find no other examples from this region and this unusual replacement is very rare worldwide.
Fluorite with Carthage Corner habit
stock #16.1-574
Elmwood Mine, Carthage
Tennessee, United States
10.3 x 6.2 x 5.6 CM (cabinet)
price: $425
Spring update

A clean textbook quality example of a gemmy Carthage corner Fluorite. The larger cube has typical frosted, stepped faces and translucent purple surfaces but the corner is glass smooth, perfectly colorless and gem clear, a window into the interior of the crystal. A modern classic habit from the Elmwood mine, this is much more impressive in person and an esthetic mineralogical curiosity.
Adamite- fan form crystals
stock #18-AX-29-112
Mina Ojuela, Mapimi
Durango, Mexico
4.6 x 3.9 x 3 CM (miniature)
price: $180
Spring update

Delicate sprays of Adamite in the classic fan form that are nicely perched on mix of Gossan and other Adamites. Attractive small miniature in fine condition, with fans up to 1.8 CM. Good luster and distinctive form this can only be from Mina Ojuela. From 2013 finds, good fans have become hard to find.
HOLD Tremolite- doubly terminated gem crystal
stock #HOLD 18.1 AX-196
Alverson locality, North Gouverneur, St Lawrence County
New York, United States
3.1 x 1.4 x 1 CM (thumbnail)
price: $0
Spring update

A remarkable thumbnail, a top quality transparent green Tremolite crystal with excellent luster. From a small find made decades ago in St Lawrence county, New York collected by Skylar Alverson. Doubly terminated, (the lower termination is less sharp and has a small contact) very sharp and choice. A slightly silky look is seen on some faces, the crystal has areas that could be faceted and is in excellent condition. These never available for sale except from old collections.
Gold- Sheet crystal habit
stock #18-AX-16-444
Round Mountain, Open Pit Gold mine, Nye County
Nevada, United States
3.1 x 2.1 x .2 CM (thumbnail)
price: $520
Spring update

A pure sheet of Gold with some flattened crystal faces and structures evident. Thin but substantial, this has a bright luster and looks great on both sides. Mined in 2006, this weighs just 1.3 grams but due to the flat form it looks very impressive for the weight. The variety of fine Gold specimens that has come out of Round mountain is incredible. Choice.
Gold in Quartz
stock #17.1-717
Henderson Mine, Chibougamou
Quebec, Canada
3.8 x 3.7 x 2 CM (small miniature)
price: $950
Spring update

Gold in crystals, sheets and massive zones densely filling a veined Quartz matrix. From the Henderson mine in Chibougamou, this is an especially rich specimen from the locale that is famed for the worlds best Cubanites. Very few specimens of Gold have been preserved from this locality, Ex Glenn Petrie, and Les Hitchings collections. The Gold is visible on every surface of the matrix, and under magnification the richness and complex delicate structures are very elegant. Total weight of 34 grams I would guess the bulk of that weight is Gold.
Fluorite- very clear blue-purple phantoms
stock #9.1-097
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
8.1 x 5 x 5.1 CM (cabinet)
price: $1250
Spring update

Outstanding classic Fluorite. A transparent, lustrous and very sharp cluster of fine zoned cubes with the elusive glassy quality that made the Minerva mine so important. Ex Ernie Schlichter in excellent condition, I can find just one small cleave on the backside, the display sides are pristine. The color is especially vivid in person. A few small dark cubes and Calcites are at the bottom and add some contrast to the main very bright crystals. Looks fine from several angles, the few available pieces in this quality range are fast getting rare and very costly.
Galena - Octahedral stacked cluster
stock #13.1-354
Mid-Continent Mine, Treece, Cherokee County
Kansas, United States
4.2 x 3.3 x 2.8 CM (miniature)
price: $230
Spring update

Very well formed, lustrous and complete on all sides, a fine cluster of bright metallic crystals. From the famed Tristate district, relatively few specimens were attributed to individual mines but this piece is noted as from the Mid-Continent mine. In excellent undamaged condition with a "gunmetal" patina a fine specimen from a classic and long closed area.
