Calcite (twinned, gemmy cognac crystals) with Sphalerite
stock #8.1-267
Elmwood Mine, Carthage
Tennessee, United States
10.3 x 5 CM (cabinet)
price: $420


This is type of Calcite that made the Elmwood mine world famous! Super sharp, lustrous gem clear (way better in person) with fine amber/cognac zones. Overall in fine condition, both main terminations are complete with recrystallized contacts and stepped tips. The small side car crystal has a tiny nick on its termination that can be hidden by display angle. A very good value for the price, as these have become very uncommon in good quality since the mines have been closed.
SOLD! Rhodochrosite with Hematite and micro Hausmannite
stock #SOLD 1059-JM-3609
Homer-Wauseca Mine, Mineral Hills, Iron County
Michigan, United States
7.5 x 4.3 CM (cabinet)
price: $265


A rare Rhodochrosite from the Iron regions of Michigan, ex. John Marshall collection. Much better than just a "location piece" the rhodos here are quite bright, clear and sharp. Most are isolated Rhombs but with some clusters in rosette form.
Elbaite (multicolor gem Tourmaline)
stock #10.1-312
Paprock, Konar
Nuristan, Pakistan
5.6 x 5 CM (cabinet)
price: $2650


A very fine and very attractive specimen! Elbaites with vivid color and gem clear quality reach 5.5 CM in a jackstraw cluster. There is practically all tourmaline with no matrix, only a few areas of minor Cleavlandite. The better Paprock Elbaites have become highly respected for distinctive color and glassy faces. This specimen is top tier, it is a rich, sharp, colorful glassy and in outstanding condition.
SOLD Siderite, Apatite (CF) and Chalcopyrite
stock #SOLD 10.1-485
Julcani, Angaraes Province
Huancavelica Department, Peru
8.5 x 5.3 CM (cabinet)
price: $0


From a small find in 2009, this is a very well presented and unusual specimen. The Siderites are up to 2.3 CM in size, lightly frosted and translucent. These rest on a well-crystallized Chalcopyrite matrix which also hosts light blue-green sharp apatites that are perfectly formed. In undamaged condition, an attractive and unusual specimen.
Sphalerite (Exceptional large crywtals) and Dolomite
stock #0249-JM-457
Pelican Mine, Picher, Tri-State District, Ottawa County
Oklahoma, United States
10.9 x 6.2 CM (cabinet)
price: $570


An exceptional, well formed Sphalerite from a long gone classic locality. Big, textbook clustered crystals reach 3.6 CM and show elegant twinning. This is far better than most "good" specimens from Tri state, it is admittedly more expensive but a very good value for the price. While this is a "black, ugly" mineral the overall esthetics and luster on this one makes this an remarkable and desirable addition for any collection.
Amethyst Phantom with Quartz and Epidote
stock #ALEC-4-404
Goboboseb Mts., Brandberg area,
Erongo region, Namibia
4 x 1.8 CM (miniature)
price: $340


A perfect miniature specimen! Sharp, bright, gem clear and lustrous, this Brandburg area specimen has everything going for it. Displays well from every angle, the pictures show it best. No damage seen under 10x magnification. This is the type of esthetics and quality that is most desired in a Brandburg!
Hubnerite (exceptional, largest from Yaoganxian!) on Quartz with Helvite
stock #8.1-098
Yaogangxian Tungsten Mine, Yizhang County
Hunan, China
12 x 9.5 CM (cabinet)
price: $3600


An important Chinese specimen and a rarity, this Hubnerite is from the one time small find at Yaoganxian in 1998. It seems these are also the largest Hubnerite crystals known from China, at 9.4 CM! Ferberite (the analog) is famous from Yaoganxian, it has produced some of the worlds best. However, verified Hubnerite is only known in a few specimens. The crystals here are attractively perched on a long Quartz prism and this displays well from either side. The color is a lustrous black to a deep brownish-red. Strong lighting shows red translucence on thin edges of the crystals as is typical for Hubnerite. The crystals are complete, somewhat jagged showing parrellel growth with full terminations. A dusting of micro Helvites (not confirmed) add a color contrast. Remarkably this specimen has no noticable damage on the delicate Hubnerite crystals. For any comprehensive Chinese collection or a Yaoganxian suite, this is something really special!
Azurite with Malachite, Duftite etc.
stock #ALEC4-591
Tsumeb
Otjikoto Region, Namibia
6.8 x 5.5 CM (cabinet)
price: $2250


A super fine, bright and colorful Tsumeb Azurite that is far better in person! In fantastic condition (with 20x magnification I found one very tiny chip), by naked eye this is perfect. The largest prism is 4 CM long. These crystals have brilliant shining luster sitting in a sculptural array showing several types of termination. A very good value for an esthetic, classic Azurite.
