Chrysocolla pseudo after Azurite/Malachite
stock #15.1-490
Lupoto mine, Lubumbashi, Katanga Copper Crescent
Shaba, Democratic Republic of Congo (Zaire)
8.3 x 6.9 x 5.3 CM (cabinet)
price: $400
May 2015

One of the most exciting new finds this year are these very colorful Pseudomorphs from the Congo. This specimen is especially well formed with big (up to 6.2 CM) sharp crystals showing Azurite form. The crystals are now hollow casts with a small amount of residual Malachite seen inside with magnification. The entire specimen is covered with tiny, sharply terminated crystals of deep blue Chrysocolla. In fine condition esthetic and eyecatching.
Stellerite
stock #ALEC-32-215
Diaboukara, Diakon, Cercle de Bafoulabe
Kayes Region, Mali
4.9 x 3.1 x 2.5 CM (miniature)
price: $330
May 2015

A relatively new find from Mali, the spherical "flowerlike" aggregates have recently been confirmed as Stellerite while the bowtie shaped crystals are Stilbites. This is a fine condition example with great form. Deep green Epidote crystals are up to 3.3 CM, overall a very attractive piece with top form.
Wulfenite
stock #15.1-289
Red Cloud Mine, Silver District, Trigo Mts, La Paz County
Arizona, United States
4.7 x 3.3 x 3.3 CM (miniature)
price: $550
May 2015

The Red Cloud mine is rightly legendary and highly regarded as a source of great Wulfenite. This example has a main crystal that is undamaged, has fine color and sits perfectly on the matrix. Remarkably, all the tiny associated Wulfenites and Calcites are in fine condition even under 10X magnification. The base and rear of the specimen was sawn flat to enable collection without damage. The saw marks are completely hidden from any display angle and the piece sits well by itself.
Calcite w. Marcasite
stock #ALEC-12-091
Brushy Creek Mine, Greely, Viburnum Trend District, Reynolds County
Missouri, United States
8.3 x 7 x 7.8 CM (cabinet)
price: $300
May 2015

A castle like structure of sculptural calcite crystals that have sharp phantom of Marcasite. Elegant form and in perfect condition, this is an old Brushy Creek specimen unlike anything seen in decades. Some areas of golden Marcasite are nestled in alcoves between crystals. The calcite spires are undulating in cross section with a vitreous luster and good translucence. A striking and unusual Calcite.
SOLD Dioptase on Quartz
stock #SOLD 15.1-454
Kambove
Katanga (Shaba), Democratic Republic of Congo (Zaire)
3.8 x 2 x 1 CM (miniature)
price: $0
May 2015

A large slender Dioptase crystal stands a full 3.3 CM tall on a contrasting matrix. The matrix is small gemmy quartz crystals that are clear enough to see the color of the host rock below, likely a Cuprite rich matrix. The Dioptase is brilliant in color, with glass-like luster. One side has a jagged contact that shows some micro crystals overgrowing on it. This has esthetics that stand out and there is no chipping or damage even with 20X magnification.
Fluorite w. Chalcopyrite inclusions
stock #15.1-454A
Ladywash Mine, Eyan
Derbyshire, England
5.5 x 4.5 x 1.8 CM (cabinet)
price: $240
May 2015

A sharp, translucent and well formed Ladywash mine Fluorite is nicely decorated with multi-hued Chalcopyrite crystals outside and inside the zoned crystals. In fine condition and with delicate hues this has no matrix at all. The Fluorites when backlit show many Chalcopyrite crystals inside forming distinct phantoms. Choice.
Epidote
stock #13.1-353
Malone Quarries, Hastings Co.
Ontario, Canada
3.5 x 2.9 x 3.3 CM (miniature)
price: $130
May 2015

Sharp. clean prismatic Epidote crystals from a less known locality. Crystals are well terminated and reach 2.5 CM in length. The only noticable damage is on the outside edges where this was removed, otherwise this is in quite good condition.
Jeremejevite gem crystal
stock #15.1-317
Erongo Mountain, Karibib
Erongo Region, Namibia
2.6 x .5 x .4 CM (small miniature/ large thumbnail (toenail))
price: $900
May 2015

A fine gem clear Jeremejevite that is much larger than average and with clean, sharp form. Ex Bill Pinch collection, distinct color zoning ranges from deep sky blue to clear. Sharp termination and glassy sides make this a very pretty example of this rare mineral. Found prior to 2002, this quality is now very hard to find.
