Barite on Rhodochrosite
stock #AX-27-255
Cerro Warihuyn - Miraflores, Huamalies Prov.
Huanuco Department, Peru
3.7 x 2.1 x 1.7 CM (miniature)
price: $90
new year 2021

Thin glass-clear undamaged Barite crystals on a minimal matrix of Rhodochrosite and tiny Barites. A very clean and attractive small miniature with no damage. The Cerro Warihuyn find of Barites is simply incredible, there have been many choice pieces in several habits and colors. This specimen is a very pale yellow-green hue in the Barites which are perfectly transparent and seem almost colorless in person. These Barites are still an excellent value for quality and esthetics at a reasonable cost.

Babingtonite on Prehnite
stock #8.1-229
Meigu, Liangshan prefecture
Sichuan Province, China
7.1 x 5.2 x 2.6 CM (cabinet)
price: $680
new year 2021

Blocky, well-defined Babingtonite crystals perched on a contrasting green Prehnite. In fine condition as seen, the Babingtonites have a mixed luster, some faces and areas are slightly matte while others are more shiny. A few years ago this find produced a treasure trove of Babingtonites, the best and largest ever seen. The source seems to have been finished and these are now becoming scarce. The better pieces have the botryoidal green Prehnite matrix like this one.

Proustite - Ruby Silver crystals
stock #12.1-248
Imiter Mine, Imiter Mining Dist., Tinghir Province
DrĂ¢a-Tafilalet Region, Morocco
5.7 x 3.8 x 2.8 CM (cabinet)
price: $3300
new year 2021

A fine and esthetic specimen of nearly pure dark red Proustite in distinct crystals. Proustite is a true mineral lover's specie, the most desirable and rare of the "Ruby Silvers". Good specimens are prized and great ones are very highly valued. This is an excellent piece very fine for the locality which is one of the small number of sources for great specimens worldwide. This displays well in several orientations, it is crystallized on nearly every surface. Incredible under magnification too, with good lighting the Proustite is a brilliant ruby red and translucent. In excellent condition damage-wise, which is also rare for this delicate mineral. Several different habits are present, some seem to be twinned and the smallest crystals are clustered in rosettes and balls, the larger crystals are more distinct and somewhat separated. Super choice.

price: $250
new year 2021

A rich nearly pure mass of small crystals of what once called Smaltite with several zones of earthy purplish Erythrite and a powdery pink mineral that seems to be Bieberite but is not analized. The specimen comes with an old Neree Boubee (Paris, France) label and one from the John Marshall collection. An old collection numbers and handwritten labels are also attached to the underside but are not visible on display. In very good condition with the many cubic Skutterudite crystals in stacks and aligned groups.

Orange River, Namakwa
Northern Cape Province, South Africa
2.9 x 2.2 x 1.8 CM (thumbnail)
price: $160
new year 2021

Dark purple Fluorite crystals that are translucent to transparent in strong lighting. A somewhat unusual locality better known for the red and orange Quartz crystals this is a nice example of this habit. The crystals are edge-modified cubes (cubo-octahedral) aligned with each other. There is no matrix except Flourite which has tiny stepped voids in the flat surfaces. The back and one side are incomplete, the front facing (display face) side is in fine undamaged condition.

stock #13.1-342
79 Mine, Hayden, Banner District, Gila County
Arizona, United States
5.7 x 2.7 x 2 CM (cabinet)
price: $50
new year 2021

A knobby growth of light blue-green Hemimorphite that has encrusted the matrix on all sides. The surface is fully covered by small sparkling crystals which are translucent and quite lustrous. From the 79 Mine, a well-known locality for fine Smithsonite and Wulfenite but which is also home to a wide array of Lead, Copper and Zinc minerals.

Galena - spinel twins, USA
stock #20.1-594
Fletcher Mine, Big Bear orebody, Vibernum Trend, Reynolds County
Missouri, United States
6.1 x 4.4 x 3.8 CM (cabinet)
price: $380
new year 2021

A flat habit spinel twinned Galena perched on Dolomite, Chalcopyrite etc. From the Fletcher Mine (Missouri, USA) the Galena is perfect, undamaged and huge for the mine at over 4 CM across. it is very unusual to see from the USA, there have been a few US finds of these over the past decade but never many. The Fletcher Mine is perhaps the most important locality for these twins and this specimen is top notch for the locale based on crystal size and esthetics. In person there is a slight iridescent patina and a slight golden hue mixed with a gunmetal silver.
