Tanzanite Multi Color zoned crystal
stock #14.1-042
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Arusha Region, Tanzania
3.1 x 2.2 x.9 (small miniature/ large thumbnail (toenail))
price: $925
Spring 2014

A sharp gemmy crystal with a strong color change and dramatic zoning. Top grade glassy luster and a lot prettier in person, this shows color changes from yellow to green in the top part, and blue, purple and red in the lower part that is hard to appreciate in photos. The overall condition is fine, there are some small contact rough spots on the backside that are not easy to see and are completely invisible from the display side. The front of the specimen is clean, sharp and undamaged. Far better in person and a great value for such a clean example!
SOLD Barite
stock #SOLD 13.1-268
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
5.1 x 3 x 2.1 CM (small cabinet/ large miniature)
price: $0
Spring 2014

A very pale blue to whitish Barite "finger" crystallized 360 degrees around with delicate leafy blades. No damage and quite attractive Barite for this location. Ex Glenn Nichol collection, these have become quite uncommon in recent years from this long closed classic locality.
Dioptase (Unusual color and exceptional form)
stock #Alec 24-097
Luishia Mine, Katanga Province
Shaba, Democratic Republic of Congo (Zaire)
4.4 x 2.5 x 1.3 CM (miniature)
price: $975
Spring 2014

Striking, esthetic and unusual, this is a fine, undamaged piece with an "odd" color hue. The Shaba Dioptase can be quite impressive but rarely this delicate and sculptural with no matrix. The color in person looks almost a Malachite green but with a brilliant glassy luster, there is good transparency too as seen in some of the best Tsumeb Dioptase. A fine specimen from anyplace this is especially nice for Katanga area.
SOLD Rhodochrosite (Strawberry) with Manganocalcite and Manganite
stock #SOLD Alec-14-378
N'Chwanning II Mine, Kalahari Manganese Filed
Kuruman, South Africa
3.4 x 2.8 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $0
Spring 2014

A sweet example of this rare style of Rhodochrosite from the famed NChwanning mine. In really fine condition, the display face has the look and texture of a strawberry with the black "seeds" of tiny Manganite crystals that look a lot like Hematite. The back side is a concave hollow with a spray of pink mangano-calcite crystals that makes a very nice association. Just a killer toenail and super hard to find now!
Quartz included by Actinolite (Tessin)
stock #9-AE 1076
Wenshan County, Wenshan Autonomous Prefecture
Yunnan, China
10.3 x 2.1 x 1.4CM (cabinet)
price: $460
Spring 2014

From a small find made 2002 this is one of the best single crystals recovered. Undamaged, sizable at over 10CM long, with excellent luster and translucence. The upper half of this shows a distinct Tessin habit but the lower half does not. Similar to some of the recent Himalayan quartz and the classic Greek included quartz, this has a noticably different look and texture.
Calcite, Quartz (Herkimer style), Dolomite, Marcasite
stock #Alec-17 836
Benchmark Quarry, St. Johnsville, Montgomery County
New York, United States
7 x 6.6 x 3.8CM (cabinet)
price: $440
Spring 2014

A wonderful combination specimen with impressive esthetics. From the Hladysz collection, this is an outstanding example of what could sometimes be found at the Benchmark Quarry 25 years ago. Bill Hladysz had exclusive permission to extract specimens there for decades, this is a gem from his personal collection now being dispursed. No eye visible damage, what may look like a chip on the calcite is not, it is a stepped edge growth.
Schorl on Fluorite with Feldspar, Quartz
stock #Alec-14-163
Erongo mountain, Usakos and Omaruru districts
Erongo region, Namibia
4.5 x 3.9 x 3 CM (miniature)
price: $750
Spring 2014

A super specimen from Erongo which displays very well and has remarkable esthetics. The black Tourmaline has brilliant luster in person and has a prismatic termination at the top and a lower termination of the fibrous type on the bottom. The contrast with the bi-color green and purple zoned fluorite gives this piece its great esthetics. In excellent condition damage wise, the photos do not do this one justice!
Caledonite, Linarite, Anglesite and Galena
stock #Alec-18-077
BlueBell Mine, Baker, Soda Lake Mts, San Bernadino Co.
California, United States
4.9 x 4.3 x 3.3 (miniature)
price: $200
Spring 2014

A rich combination specimen with lots of bright well crystallized Caledonite mixed with contrasting bright blue Linarite. The matrix is mostly a highly oxidized Galena and hosts crystals of Anglesite, Cerussite and what may be massive Leadhillite along with a few unknown micros. This could be turned into several very good thumbnails since the specimen has good crystals on every side, but I like it as is.
