Clear Fluorites (very light green) are the matrix for Native silver, Acanthite and other silver minerals. Some of the Fluorite is included by these minerals - it is best appreciated with magnification. A single sharp Sphalerite crystal is partially coated with acathite and a film of silver. Micro crystals that appear to be polybasite are also noted. A very different sort of Silver specimen!
A rich piece with lots of color and interesting associations. A 2.6 CM modified cube Fluorite sits atop bright Rhodocrosite and a dense mix of Silver in wire clusters, Acanthite, Pyrite and some unidentified sulfides. A fine example of the complex intergrowths from this unusual deposit.
A very fine, large (3.9 CM) sharp and glassy Sphalerite sits on the matrix of Dolomite coated with quartz and minor calcite. When backlit the Sphalerite glows Orange Red. The crystal is complete with no damage. Very esthetic.
The most desirable style of Herkimer "diamonds" is the the Black Stem scepter. These only occur in a single small zone and are not currently being found. This is a good, clean and undamaged example collected in the early 90's. Very distinct phantoming and lots of interesting inclusions.
Resuperferolitica Mine,Santa Eufemia
8 x 6 CM (cabinet)
Ex. John Marshall collection, a very well crystalized Santa Eufemia Pyro with large individual crystals that exceed 1.6 CM. This is overall in excellent condition and is crystallized on 2 sides with large vugs filled with sprays and freestanding individual crystals. A super display peice from a very important locality.
Sphalerite on amethyst
Commodore#5 Mine, Amethyst Vein, Creede District, Mineral County
8 x 6 CM (cabinet)
Very attractive, classic Colorado association with the main Sphalerite crystal of 2.9 CM size on a contrasting purple matrix. No damage, displays nicely, and the Sphalerites are translucent under strong light and are a deep yellow color.
Rutile on Kyanite and Goethite
Graves Mt., Lincoln Co.
6.6 x 4.3 CM (small cabinet/ large miniature)
A small but fine and esthetic specimen from this great locality. Lustrous clusters and single crystals (to 2.3 CM) are nestled jewel like in a mass of interlocked irridescent plates of Goethite . The contrast is excellent and overall the condition is fine too, but there are some very small edge chips that are not evident without careful examination and magnification. This is an older piece with a great presentation and far higher quality than most anything I have seen from recent mining.
From the oldest known location for Turquoise crystals (for many years the only one) this is a well covered example. Crystal crusts are on several sides of this piece and the color and sharpness is far better than most. The locality is closed and was probably the best site in the world for these. With a little magnification it is easy to see the sharpness and clarity of the triclinic crystals on this piece.
