Cubanite-large twinned crystals
stock #AX-24-530
Henderson Mine, Chibougamou
Quebec, Canada
3.4 x 1.7 x 1.4 CM (miniature)
price: $2450


Unusually large, sharp lustrous and very well defined Cubanite. Although Cubanite has been found at several locales in the world, the only source of fine crystals was the Henderson Mine, now long closed. There will never be any more of these which are by far the worlds best Cubanites. This specimen has a super dispaly face with very sharp striations and clear twinning. Some contacting on the back but the front displays very well. Specimens of this quality can only be had from old collections being recycled, and this size is almost never seen.

Quartz included by Hollandite stars
stock #7.AE-351
Ambatofinandrahana Department, Amoroni Mania Region
Fianarantsoa Province, Madagascar
10 x 5.6 x 2.8 CM (cabinet)
price: $330


A pair of closely joined Quartz prisms showing star inclusions of Hollandite. The main crystals growing from a cluster of smaller Quartz and are clear enough to clearly see the radiating bursts of dark Hollandite crystals. From finds over 15 years ago, these are not being found anymore as far as we know. The Quartz is also in very good condition, most of the other specimens in the find had significant chipping. A nice addition to a Quartz suite or any collection of inclusions.

Pyrargyrite -classic, very rich
stock #18.1-272
Himmelsfurst Mine, Brand Erbisdorf, Freiberg district, Erzgebirge
Saxony, Germany
7.5 x 7.2 x 5.3 CM (cabinet)
price: $1500


A really fine, large, heavy and rich Ruby Silver from the classic locality of Freiberg. Two large faces are densely encrusted with many dark to bright red crystals in several habits, and whole dosplays well from several angles. A few crystals have typical bruises the vast majority are perfect and the condition is far better than most of these old and delicate pieces. Some dark native Silver is also noted on the matrix. Displays well from several angles, the old label which had been affixed to the piece is damaged and incomplete but the word Frieberg is clear. We are informed that this matrix, habit and style is a perfect match for the Himmelsfurst mine and is clearly a very old piece. The Pyrargyrite is still a good red color despite the age and some darkening, much better than usually seen on these. The Pyrargyite is also set off by some associated milky Quartz and Calcite so it really stands out on display,. The crystals and rounded masses also are protruding well from the matrix which adds a good texture. A very choice, large classic European Ruby Silver that is especially fine in person.

Calcite "butterfly twins" with Hematite
stock #18.1-657
Leiping Mine, Leiping, GuiyangCo., Chenzhou Prefecture
Hunan Province, China
4.3 x 3.2 x 2.7 CM (miniature)
price: $280


A juxtaposed pair of "butterfly" twin Calcites with bright faces, fine clarity and red Hematite phantoms. From the last mining at Leiping, these are excellent examples from this locality. These twins made big news in the mineral world when found in 2002, partly because they looked so much like the classic British twins from over a century ago. Sharp. clean and elegant these are modern classics that look like the vintage old world classics.

Hexagonite - rare terminated Mg Tremolite
stock #19.1-377
Gouverneur Mine, Fowler, St. Lawrence County
New York, United States
2.8 x .8 x .3 CM (thumbnail)
price: $800


A rare, choice gem clear thumbnail of lilac color Hexagonite (var of Tremolite). The termination on this is complex being made of many tiny points in a tapering structure. Transparent with some color zoning seen when backlit. I believe that St. Lawrence County is the only place where this mineral occurs being found at just 4 locations. However only the Gouverneur Mine ever produced any of this sort of clear terminated crystal and not many of them. This was named when it was thought the crystal form was Hexagonal, however it was later determined to be Monoclinic. The crystal here is in fine condition, has clear striations along the prism faces and a very rich color.

Stannite, Quartz and Arsenopyrite
stock #AX-15-251-(C288)
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
7.1 x 4.3 x 4.2 CM (cabinet)
price: $650


From the "golden age" of mineral finds at Yaogangxian, this is a super choice Stannite. Ex Shields Flynn collection, the Stannites are bright brassy, well formed, undamaged and very rich. This specimen was exhibited at Tucson in the TGMS displays in 2005 celebrating the minerals of China. Most pieces from this find had much more Arsenopyrite and or Sphalerite than Stannite, this is almost all Stannite with clear Quartz crystals adding a nice accent. Most will agree that the old Yaogangxian finds were the best ever found. This specimen is well better than typical and now Chinese Stannite is rarely available in such size and attractive quality.

Elbaite -gem Tourmaline
stock #19.1-342
Usakos, Karibib District
Erongo Region, Namibia
2.7 x .9 x .9 CM (thumbnail)
price: $160


A single, doubly terminated and gemmy clear Elbaite crystal from the Karibib. Namibian gem Tourmaline of any quality has become quite uncommon, it was last being found almost 20 years ago. Complete and in nice condition this one shows the striated faces and flat terminations that is typical of these Karibib crystals. Nearly all facet grade, the interior is transparent and clear deep green.

Sphalerite - classic USA
stock #19.1-375
Joplin Field, Tri State District, Jasper County
Missouri, United States
11.3 x 9 x 4.8 CM (cabinet)
price: $1600


Large, esthetic and in perfect condition, this is an exemplary old Tri-state Sphalerite, mined before 1940. The Joplin field was at one time a seemingly endless source of mineral specimens, though really fine, undamaged pieces were very rare. The last of these mines have all been closed for more than 50 years, and the best specimens came out long before then. This is a superb Sphalerite with large distinct crystals that stand out from the matrix. Crystal faces show complex striations, etchings and some twinning, these have a choice silky luster that shows these structures well. This is incredible in person and very much a superb piece from this now legendary area.
