Superb pseudomorph in a complete crystal, double terminated and far sharper than any other I have seen. Classic specimen with a Wards label dating this to over 100 years ago, (after 1913 shortly after George English began to work there). The label bears his handwriting. The Talc is the Steatite variety and more hard than other Talc so the condition of the replacement is nearly perfect. A fine piece for a Pseudomorph suite, and a great old classic on its own.
Elbaite - curved, rehealed crystal
stock #18.1-197
Barra do Salinas Mining District, Coronel Murta
Minas Gerais,
Brazil
3.8 x 3. 2.8 CM (miniature)
price: $390
Spring update
An older, fat and substantial Elbaite crystal with a slight curve where it has rehealed. Multi color, 48 grams and with a white fibrous zone at the bend point. There is scattered bits of Clevelandite on a few faces. Good luster and quite sharp complex termination. Better in person too.
Fluorite with Carthage Corner habit
stock #16.1-574
Elmwood Mine, Carthage, Smith County
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 #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.
Gold- Sheet crystal habit
stock #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.
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.
Vesuvianite
stock #18.1-193
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
Quebec,
Canada
3.1 x 2.1 x 1.2 CM (thumbnail)
price: $180
Spring update
Jeffrey Mine thumbnail with a main 2.5 CM crystal standing above broken but recrystallized smaller Vesuvianites. The main crystal is in good condition as seen, the color is good and displays well. Attractive from all angles, a nice example of the habit from this prolific but closed locality.
Titanite var Sphene - Classic New York
stock #17.1-804
Diana Township, Lewis County
New York,
United States
7.9 x 4.4 x 2.8 CM (cabinet)
price: $220
Spring update
Vintage specimen with old EB Underhill label. Underhill donated his collection posthumously to Amherst College in 1888, so this piece and his handwritten label is older than that. Not many of these labels survive today and the Sphene specimen is also a very rare example from a classic locale. I have never seen another quite like this, the luster is very bright on the slender dark gem clear crystals in the protected vug. Microscope reveals tiny Clinochlore and what may be colorless Fluorites, not known from this locale. A nice slice of mineral history.
