Copper Pseudomorph after Azurite rosette
stock #15.1-1118-(SM3654)
Copper Rose Mine, Georgetown, Grant County
New Mexico, United States
4 x 2.9 x 2.7 CM (miniature)
price: $320
Spring 2017

A fantastic Copper after Azurite rosette that is sharp, very large and quite old. An early Wards label (likely 1900-20) is included and one from the Charles Noll collection as well. This habit and style is unique to this locality and this specimen perfectly preserves the form of the Azurite crystals and the rose shaped cluster they grew in. Nice patina and in perfect condition.
Kolwezite with Spherocobaltite and /or Cobaltoan Dolomite
stock #Alec 12-257
Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
7.8 x 6 x 5.6 CM (cabinet)
price: $480
Spring 2017

Bright and colorful, this is a very rich specimen of the rare mineral Kolwezite. Original labels list Spherocobaltite as well, this is hard to confirm visually, there is certainly lots of Cobaltoan Dolomite present which can look somewhat similar. In excellent condition, formerly in the Ruth and Andy Palmer rare species collection and the William Hladysz collection as well.
Galena ps after Pyrrhotite -ex Minette Collection
stock #Alec-12-249
Herja Mine, Chiuzbala , Baia Mare
Maramures, Romania
9.3 x 6.3 x 5.1 CM (cabinet)
price: $875
Spring 2017

A killer esthetic pseudomorph that has bright flattened Galenas arranged epitaxially and completely replacing large Pyrrhotite crystals. This was previously in the Minette, Loud and Hladysz collections. This is also the very best example of this unusual replacement I have seen, in excellent undamaged condition and impressive from all sides. The original Pyrrhotite crystals shapes are perfectly preserved and reach to 7.5 CM across.
Celestite and Calcite
stock #Alec-19-296
Pugh Quarry, Custar, Wood County
Ohio, United States
9.8 x 7.1 x 6.1 CM (cabinet)
price: $380
Spring 2017

Excellent bright blue Celestite crystals dominate this cabinet sized matrix. From the Pugh Quarry a classic US source of fine Calcite and more rarely Celestite. There is a broken crystal on the backside of the specimen that is not visible from the front. otherwise the crystals are in excellent clean condition. A very eye-catching specimen with far better than usual color.
Andradite var. Demantoid, Gem crystals with color change
stock #17.1-006
Antetezambato, Maherivaratra, Ambanja District
Antsiranana Province, Madagascar
6.5 x 4.9 x 3.1 CM (cabinet)
price: $900
Spring 2017

Top color and luster, bright sparkling gem Garnets are perched on a contrasting matrix of micro Garnets from white to pale green. In perfect condition damage wise, this is far better in person as the crystals are more brilliant than can be photographed. The color change from daylight to incandescent is also quite striking, daylight (or good led lighting) brings out an intense apple green as seen, the last photo shows the color by incandescent lighting. We searched out and examined a lot of the best Demantoids from Madagascar and only a few we consider great values. This is one that stands out.
Fluorite with epitaxial Calcite
stock #Alec-15-270
Dongpo Mine, Yizhang County, Chenzohou prefecture
Hunan, China
10.5 x 7.8 x 5 CM (cabinet)
price: $800
Spring 2017

Like snow on mountains, Fluorite crystals with sharp phantoms are selectively coated with Calcite rhombs. Ex. Shields Flynn collection, a choice display piece from the little known Dongpo Mine. In excellent condition overall, the only damage is unseen at the bottom outer edges where this was attached, the Fluorites and Calcite are pristine. Some cubes show complex corner modifications that are distinctive for this mine. Not the usual Chinese Fluorite!
Calcite
stock #13.1-118
Mine 884, Leiping, Guiyang County, Chenzoh Prefecture
Hunan, China
3.6 x 2.5 x 2.1 CM (small miniature/ large thumbnail (toenail))
price: $330
Spring 2017

A perfect toenail of incredible gem clear Calcite from the finds in 2000 in Leiping. This find was huge news in the mineral world because the Calcites were so much like the prized 18-19th century British specimens. This find too has been finished and these are already modern classics. Far better than the photos show -top luster, glass clear transparency and textbook perfect form. A tiny bit of Hematite is noted on the matrix.
Wulfenite with Mimetite
stock #Alec-21-043
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
3.2 x 2.9 x 1.8 CM (miniature)
price: $300
Spring 2017

A classic, fine Rowley mine Wulfenite with brilliant orange crystals scattered on bright Mimetite. A delicate piece with great luster it is remarkably undamaged and pristine. From the "last gasp" mining of 2 years ago, the locale is now shut down and will likely never be re-opened. A great American classic locality, the Wulfenites from here are like no others and immediately recognizable. Small but very choice.
