Native Silver w. minor copper
stock #8 US 941
Wolverine Mine, Wolverine, Houghton Co.
Michigan, United States
12.2 x 5.2 x 1 CM (cabinet)
price: $1200


A very large and rich Silver from the Wolverine mine. This has almost 100 percent Silver but there is a tiny sploch of Copper on one edge. The silver has a patina ranging from near black to irridescent to brighter silver tones. Some of the silver at first glance looks copperlike. Some bits of matrix are included but this is nearly all metal. With low magnification some herringbone and crude crystals are seen as well. In outstanding condition this is a classic and heavy chunk of Michigan Silver!
Copper -Flattened spinel twins in branching array
stock #AC-097
Central Mine, Keweenaw Co.
Michigan, United States
6.8 x 5.1 CM (cabinet)
price: $700


A very fine copper branch, well crystallized and with great esthetics. This piece still has a few flecks of adhering matrix (which could be removed). The definition and sharpness of the flattened crystals is outstanding. It is hard to tell what the vintage of this is, but this is clearly a very old piece, sold by Shortmanns in the 1950's but perhaps over 50 years older than that. There is a lot of good copper in the market but this is really different and distinctive!
Rhodochrosite with Native Silver
stock #8.1-419
Wudong mine, Liubao, Cangwu Co. Wuzoh
Guangxi, China
4.1 x 3.8 CM (miniature)
price: $1650


A big rich red translucent rhomb that is quite a good Rhodo on its own. However, this has the addition of wire silver and silver "skins" in several spots. The largest wire is about 7mm long and easily visible. This locality has produced only a few good examples of this rare association. This is an outstanding one. The crystal is transparent to translucent and glows with any backlighting. There is the typical internal stress fractures visible inside, a contact on the backside, and cleaving on the exterior as seen in the photos. Despite this it is a very attractive, displayable, bright and eyecatching crystal in the top percentile of quality from this location. A most desirable piece for a Chinese suite, Rhodo or Silver collection or just for the novelty and color!
Kunzite (Spodumene)
stock #7 PAK-007
Chitral, Chitral Valley
North West Frontier Province, Pakistan
4.4 x 3 CM (miniature)
price: $150


A sharp, attractive Kunzite with an unusual form caused by two parellel crystals with staggered terminations. Deep color, fine luster, and a more "prismatic" look than most Spodumene. Some slight edge wear is visible but it is very minor, not distracting to this nice gem crystal.
Tourmaline (elbaite)
stock #8 PAK-743
Paprock, Konar
Nuristan, Afganistan
4.6 x 3.5 CM (miniature)
price: $280


Attractive and sharp miniature presenting 2 terminated pale pink to clear (achroite) tourmaline posed esthetically on matrix. No damage is visible to the naked eye, a very tiny chip is found under 10X magnification. The bigger crystal is 3.1 CM long. A very good value for such a clean and pretty specimen.
SOLD Acanthite with Polybasite
stock #SOLD 8-PER-810
Uchucchacua Mine, Oyon Province
Lima Department, Peru
2.9 x 1.6 (thumbnail)
price: $0


A very nice Silver thumbnail. Sharp for the locality and for the specie, this is a lusterous aggregate of highly modified Acanthites that are basicly dodecahedral. There are bright and sharp up to 5mm crystals of Polybasite nestled between the larger Acanthites. Associated with Pyrite, this is very good for the locality.
Bixbyite
stock #8 UT THUMB 788
Thomas Mountains
Utah, United States
2.9 x 2.7 CM (thumbnail)
price: $75


A lusterous thumbnail with several sizable and sharp bixbyites, on a matrix of topaz (cystallized with "sand" inclusions). The crystals all have some contacting and included topaz and the matrix topaz is somewhat crude. Despite this the largest crystal of Bixbyite is sizable at 1.4 CM and very bright, and this is well over the average in general quality.
Tourmaline (elbaite) with hollow termination
stock #8 DK -092
Palo Alto, San Diego Co.
California, United States
3.4 x 2.6 CM (small miniature/ large thumbnail (toenail))
price: $700


From the classic California pegmatites this is a very different and remarkable tourmaline! The bi color crystal is sharp, glassy has some "cats eye" fibers and a lot of gem clear areas. However what makes this exceptional is the central hole in the center of the termination. This hole is roughly triangular in cross section, like the exterior of the crystal. Furthermore, it is striated on the inside and runs thru more than half of the crystal before it ends at a "negative termination" . The crystal has some very nice color, minimal damage (not eye visible) but the hoppered area is what makes this really impressive. Good for any gem crystal collection or as a conversation piece.
