Malachite - polished stalactitic section
stock #17.1-700
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
6.8 x 5 x .4 CM (cabinet)
price: $350
Pre Holiday 2017

Sections of stalactitic Malachite can be quite esthetic, especially when the form is more complex and with good color banding. This is an excellent example cut from materials collected in the 1990s. Far better quality and form than average for this sort of slab. The double eye on this piece is especially striking. Polished on both sides but the "back" as seen was near to top knob of the malachite form and so has much more rind. Complete with great form and contrast.
Fluorapatite (Apatite CaF)
stock #17.1-701
La Marina Mine, Pauna
Boyaca, Colombia
1.4 x 1 x .6 (thumbnail)
price: $320
Pre Holiday 2017

A small but incredible gem clear Apatite crystal with the desirable bright pink color. From the La Marina mine in the Emerald belt of Boyaca province that is known for world class Euclase. This has a thin white line inside much like a fadden string which has been noted rarely from this locale. The crystals in the mine often have elongated or widened, distorted prisms, which is seen on this one as well. Very sharp, a very small chip is on one back edge but overall visually clean on the front display side. We visit Colombia several times each year looking for Apatites like this. The production is very sporadic and never large, some years none are seen. This is well above average for color, clarity, form and condition.
Copper with and in Calcite
stock #15.1-892
West Vein, Phoenix Mine, Phoenix, Keweenaw County
Michigan, United States
6.8 x 3.4 x 2 CM (cabinet)
price: $700
Pre Holiday 2017

Esthetic and not typical at all! Native Copper in leafy tendrils holds and is inside very clear crystals of Calcite. The Calcite is in blocky cube forms with complex growth hills on some faces and colored by the inclusions a bright Copper hue. The Calcites are glassy and the whole composition is very attractive. Some contacts are noted mostly on the backside of the specimen, overall in fine condition. I have not seen another of this style in many years.
Anglesite -Unusual form at this locale
stock #16.1-338
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oriental Region, Morocco
3.2 x 2.9 x 2.1 CM (miniature)
price: $180
Pre Holiday 2017

Blocky transparent crystals of white Anglesite with inclusions of Galena seen clearly inside. From the mines at Touissit, this is not the well known form, habit or color most often seen. The form is similar to some specimens from Sardinia or Tsumeb. The condition is good with very minor edge chipping on a few areas not very evident.
Cuprite with Malachite, Plancheite etc.
stock #17.1-702
Mashamba West Mine, Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
5.8 x 3.7 x 3.4 CM (cabinet)
price: $460
Pre Holiday 2017

Big, dark red and lustrous Cuprite Octahedrons are nestled in light blue Plancheite and dark green Malachite. Fine contrast, esthetics and in very good condition. The backside is contacted but not damaged, pitting and face voids are natural some with Plancheite inside. Individual octahedrons are up to 1.8 CM, some with nice edge modifications quite rare at this locale. These have not been coming out for almost a decade. Choice.
Cobaltoan Calcite
stock #16.1-002
Kolwezi, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
6.3 x 5.8 x 3.2 CM (cabinet)
price: $280
Pre Holiday 2017

Colorful bright specimen with rhombs to 2.4 CM, ex Victor Yount collection. In fine condition, at one edge the overgrowth of Cobaltoan Calcite has not covered the underlying Calcite rhombs and the structure is well exposed.
Euclase- colorless gem crystal
stock #8-AE-791
Conselheiro Pena, Doce Valley
Minas Gerais, Brazil
3 x 1.6 x .7 (small miniature/ large thumbnail (toenail))
price: $380
Pre Holiday 2017

A perfectly clear, well terminated and sharp Euclase crystal. The faces show fine striations and the top shows a dual tip termination that is unique in our experience. If this was a blue Euclase with this clarity and sizeit would be valued in the 5 figures, but as it is colorless that is clearly not the case! An excellent example that is larger than most from this area of Brazil.
Chalcedony -"caviar agate" on red Scolecite
stock #17.1-705
Malegaon, Nasik
Maharashtra, India
3 x 2.7 x 2.1 CM (small miniature/ large thumbnail (toenail))
price: $420
Pre Holiday 2017

An unbelievable new find! We were able to obtain what so far are the best pieces of the small but impressive pocket in Malegon, Nasik, India. The red to orange Scolecite is in a rounded mass composed of radiating needles. An impressive matrix for the small spheres of Chalcedony (or technically agate) looking like fish eggs in multiple colors. These were named "caviar agate" shortly after they first appeared, and are an amazing companion to the "grape agates" from Indonesia. This has the caviar eggs on small needle-like stalks with excellent form, color and quality. Displays brilliantly under good light as seen in these photos. A fine addition to any suite of Quartz, Agates, Indian trap minerals or simply esthetics.
