Calcite- Optically clear single crystal ex. W. I. Johansson
stock #15.1-719
Charcas
San Luis Potosi, Mexico
4.5 x 3.1 x 2.2 CM (miniature)
price: $300
Winter 2016-17

Slightly frosted on some faces, sharp, clear and in fine condition, this old specimen is from 1960s vintage finds at Charcas. Selective frosting adds to the visual interest and the form is textbook perfect. The termination shows a nice effect with the selected areas outlining a central hexagon. Nothing quite like these Calcites has since been found.
SOLD Amethyst

Boekenhoutshoek, Mkobola
Mpumalanga, South Africa
5.8 x 3.8 x 4.6 CM (cabinet)
price: $0
Winter 2016-17

The deep purple is the most desired (and most expensive) of all the "Cactus" quartz They have not been found in any of the last years of mining. This one is that rich color and has great luster. From the front and sides this is perfectly undamaged. A tiny chip exists on the back of one termination that does not show, yet this keeps the price much lower that would be otherwise.

price: $380
Fall 2015

Fine, sharp silver Carrollite crystals are set on contrasting matrix in an esthetic arrangement. The crystals show complex modifications and growth patterns. Some micro crystals of what looks like Vesigneite are also present. Green copper staining and secondary minerals adds additional contrast. In very good condition which is remarkable for such a delicate mineral. Far better than average.

An excellent Psuedomorph from Niaca with bright, lustrous metallic gold and silver hues. The condition is excellent and the esthetics are far better than most. These have occasionally been found in this famed mine, but never very many and none for some years.

Fall 2015

Very striking, esthetic, sharp and sizable Azurite with deep color and areas of Malachite alteration. In excellent condition and with textbook quality form. Despite all the many Azurites from Tsumeb over the past century, such fine examples have always been highly prized and are rarely available. Much better in person

An old Santa Eulalia Rhodochrosite with sharp, deep red and gemmy crystals in fine condition. The clarity of the Rhodos sets this apart and is quite esthetic. The contrast with the sulphide matrix is especially attractive.
