Amethyst on Calcite
stock #12.1-113
Karur
Tamil Nadu, India
7.4 x 5.8 x 2.4 CM (cabinet)
price: $260


A small cabinet sized plate of small greenish Calcite crystals is the matrix for a complex array of doubly terminated Amethyst. The Quartz is in perfect condition, very lustrous and fully transparent, it makes a great contrast with the vivid purple on green. This has a flowerlike look in person, Some of the crystals are sceptered and reverse sceptered. Good magnification also show some slender red inclusions that may be hematite or another mineral. Pretty and unusual a very nice example from this moist inusual locality at Karur in Southern India.

Barite on Calcite with Pyrite
stock #6.2-909
Dachang Ore Field, Nandan
Guangxi Province, China
4.8 x 4.3 x 2.1 CM (miniature)
price: $650
Pre Tucson

A quite usual and attractive gemmy Barite/Calcite combo from the Nandan area (Guangxi, China). We were at this less well-known mining area in 2004 and a few miners had just found these gem clear Barites, some with "Mercedes" style Calcites. We selected the best 20 pieces or so and quickly sold everything We never could get anymore like this and the mine has been closed for a few years. This piece came back to us recently and is ready for a new home. Like most in the find the Barite is not absolutely perfect, there are micro chips most of which are on the backside. It still looks great from most angles but is not for perfectionists. The Calcites make a great contrast and add a lot of interest. They are white flat discoidal type with dark Pyrite lines that create the Mercedes shape. The color and luster of the Barite are excellent and there are phantoms of dark inclusions that are almost certainly Pyrite. The small bits of damage are certainly unfortunate, (we never did find any without at least a little) but they are not a major distraction and keep the price a lot lower than if this was absolutely perfect. An excellent older vintage Chinese piece. The Nandan area had many small mines that were a very interesting source of polymetallic ores and some great specimen minerals. We miss it!

Andradite - Demantoid
stock #22.1-696
Black Lake, Thetford Mines, Les Appalaches, RCM
Quebec, Canada
5.5 x 5.3 x 23.1 CM (small cabinet/ large miniature)
price: $550
Pre Tucson

A fine mint green Garnet crystal with the unusual and quite rare flattened habit sits atop the matrix of druzy Andradites. The main crystal is just over 1.1 CM across and is complete, undamaged and in tabular form. From the finds at Black Lake (Quebec, Canada) about 20 years ago, this is far above the average quality known from this important locality. Black Lake Quarry was not very far from the larger and more famed Jeffrey Mine, but had a somewhat different mineralization. More Andradite than Grossular Garnets are known from here and the predominant color was green Demantoid. Good specimens of this quality are quite rare on the market, much less common than Jeffrey Garnet. In excellent condition.

Rhodochrosite with Elpidite etc.
stock #23.1-151
Mont Saint-Hilaire, Monteregie
Quebec, Canada
3.7 x 2.6 x 3.2 CM (small miniature/ large thumbnail (toenail))
price: $690


A superb small miniature or "toenail" with a sharp triagonal Rhodochrosite perched on top. In excellent condition the Rhodo is the classic form from Mont St. Hilaire, and has the triagonal center hopper in the center of the largest crystal. Lots of additional micro crystals and species are on the specimen but the Rhodochrosite is really the dominant focal point, it is 2.2 CM across and has very good color. What looks like chipping or damage on a top edge is actually well crystalized with tiny step faces. The Rhodochrosites of Mt St Hilaire took several forms but the triagonal crystals are still the most distinctive and are incredibly rare at all other localities. This specimen was found more than 30 years ago, they were never common and there is nothing now. Classic and esthetic!

SOLD Fluorite - spinel twins
stock #SOLD 23.1-224
Hohenstein Massif, Omaruru District
Erongo Region, Namibia
2.8 x 1.4 x 1.2 CM (thumbnail)
price: $0
Pre Tucson

Killer thumbnail of multi color Fluorite in a flat and elongated spinel twin form. From the 2021 pocket on Hohenstein (Erongo, Namibia) which had a very special and unique look to many crystals, this is a perfect, complete and choice small wonder. The internal color play is very impressive in person, purple, green lighter violet and yellow to orange colors are zoned. The yellow-orange is a concentrated in a faden-like line that runs the length of the crystal. It is almost impossible to describe the crystal complexity, some faces are glass clear, these alternate with some frosted or etched faces. Looks fine from almost any angle and with backlight glows very well. We were able to select our specimens very early from the pocket contents and all were chosen with care for best quality, esthetics and interest. A few tiny crystals are scattered on one edge and are also spinel twins. This find is among the most important of the past few decades of Erongo Fluorite, the habit and quality are unlike anything else.

Pyrrhotite - rare penetration twin
stock #14.1-100
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Russia
4.1 x 2.9 x 2.8 CM x 2.9 (miniature)
price: $760
Pre Tucson

Textbook perfect, complete and sharp this is an unusual type of twin for Pyrrhotite. With small areas of Galena and Sphalerite, this is essentially all Pyrrhotite. In excellent condition as seen, no damage at all but the usual tension cracks are seen as is typical though there is no repair or instability. Great golden patina and displays well from most any angle, a choice Dalnegorsk piece and an excellent twin Pyrrohotite. Since Pyrrhotite is generally found in hexagonal crystals, the penetration twin has 4 terminations showing with six sides on each end, all at 90 degrees from each other. This is only the second such twin I have ever seen.

Fluorite - zoned, new find from southern Illinois
stock #23.1-263
Leadhill Mine area, Cave-in-Rock, Hardin County
Illinois, United States
5.6 x 4.5 x 3.8 CM (small cabinet/ large miniature)
price: $600
Pre Tucson

From a series of small finds at the Lead Hill Mines in 2022, this is a glassy, sharp and vivid piece. The zoning is the classic phantoms of cubic internal boxes. Color varies from deep purple to a light violet to almost colorless. There is internal Chalcopyrite as well but very small. The base and backside have cleaves where this was in contact but most of the specimen is fine. A few from this find had zoned fluorescence, this one does and has some zones of the rare red color along with more typical blue and white zones. For several years we all have been missing new Fluorites from the great southern Illinois districts, the mines are closed and mostly exhausted. This recent trickle of nice pieces are very welcome in the mineral community. They are also a bit different from others in the region and make a nice addition for any good Fluorite suite.

Zircon (Cyrtolite) on Nepheline and Lepidomelane
stock #20.1-817
Bancroft, Hastings County
Ontario, Canada
3.3 x 2.7 x 2.4 (thumbnail)
price: $140
Pre Tucson

A well-positioned Zircon crystal dominates this thumbnail specimen from Bancroft, Canada. The Zircon from this locality are variety Cyrtolite and this specimen has a very well-formed red- brown crystal that is perfectly exposed and is doubly terminated. Ex Hitchings collection obtained in 1969. Slightly translucent the crystal is not damaged but on the backside is some contacting not seen from any display angle.
