stock #21.1-377
N Chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
3.6 x 1.8 x 1.4 CM (small miniature/ large thumbnail (toenail))
price: $360

Bright yellow crystals of the rare mineral Jourvaskite on matrix. Although small, up to just 1.5mm, these crystals are huge for the specie. Vivid color and in excellent condition. The backside of the matrix is massive Manganite with a thin layer of Rhodochrosite underlying the Jouravskite, Quartz and what seems to be Xontolite. A choice and pretty specimen of a rare mineral; ex Terry Szenics collection.

Diopside - doubly terminated gem crystal
stock #21.1-163
Merelani Hills, Lelatama Mountains, Simanjiro District
Manyara Region, Tanzania
3.2 x 1.7 x .9 CM (small miniature/ large thumbnail (toenail))
price: $680

A perfect, complete doubly terminated green Diopside that is fully transparent gem. Of the dozens of these Diopside seen on Mindat none are doubly terminated, this is a very rare example. Some complex geometric internal structures are seen with a close exam as are a few internal Graphite crystals. No damage, and very glassy luster. From Merelani, famed for Tanzanite crystals, these gem Diopsides are much less common on the market, and doubly terminated crystals are very rare in any quality.

Gordonite (rare Phosphate) on Variscite, type locality
stock #20.1-139
Little Green Monster Mine, Clay Canyon
Utah, United States
3.4 x 2.7 x 1.9 CM (small miniature/ large thumbnail (toenail))
price: $450

A rind of tiny, glassy Gordonite crystals on a Variscite nodule that has a tiny bit of Crandallite as well. From the type locality in Utah. This is the type locality for this specie found during the famed excavation project by Ed Over and Arthur Montgomery in the 1930's. The individual micro crystals are up to 1.5 MM in size, which is fairly large for the specie. These are both isolated, free standing and in radiating sprays. Remarkably the main cluster of crystals extends across 1.5 CM which makes this specimen an incredibly rich example, very fine for this rare specie.

Wulfenite with Calcite etc.
stock #21.1-332
Mina Ojuela, Mapimi
Durango, Mexico
3.6 x 3.3 x 2.6 CM (small miniature/ large thumbnail (toenail))
price: $90
Late Summer 2021

Older blocky style Wulfenite crystals with small Calcites on gossan matrix. The majority of the large crystals are complete and slightly distorted with a burnt orange color and good luster. In good condition overall, some minor damage exists but is not very evident. Another modern classic from Ojuela.

SOLD Brookite on Quartz - classic USA
stock #SOLD 21.1-338
Magnet Cove, Hot Springs County
Arkansas, United States
3.4 x 1.5 x .8 CM (small miniature/ large thumbnail (toenail))
price: $0
Late Summer 2021

A sharp and quite lustrous Brookite crystal 1.1 CM across, with textbook perfect form, is perched on a milky Quartz crystal. The Brookite has an unusual blue iridescence on some faces, though it mostly looks black. A classic locality that is well-known for good Brookites that are very different from those well-known from Pakistan. An older specimen collected before 1969. This could be trimmed to be a thumbnail if desired but it is quite nice as is. The wider faces have complex geometric stepped structures well-presented. There is no damage at all.

Malachite pseudo after Azurite - USA classic
stock #15.1-362
Sacramento Mine, Bisbee, Warren District, Mule Mtns, Cochise Co.
Arizona, United States
3.8 x 3 x 2.3 CM (small miniature/ large thumbnail (toenail))
price: $650
Late Summer 2021

A textbook perfect pseudomorph that has the exact form of the original Azurite crystal fully altered to a velvety Malachite. A few tiny bits of Cuprite and Copper are seen with strong magnification on the gossan matrix, but overall this is all about the very fine Malachite. A classic US specimen from the Sacremento Mine at Bisbee, we are told this is from a pre 1929 collection but there are no old labels. Certainly no specimens of this quality have been found for many decades, and will not be seen again.

Pyrite - altering to Hematite/Goethite
stock #7-AE-230
Green Monster Mountain, Prince of Wales Island, Prince of Wales Island
Alaska, United States
3.5 x 3.1 x 2.6 CM (small miniature/ large thumbnail (toenail))
price: $90
Late Summer 2021

From the famed Green Monster Mountain (Alaska) a Pyrite crystal partially pseudomorphed by Iron Oxide species. This locale is well-known for fine Epidote but the Pyrite pseudos are seldom seen. The Pyrite on this has good somewhat iridescent luster on some faces. Several faces also have some fissures and and stepped zones. The pyrite form is distinct and the specimen seems to be solid and stable.

SOLD Fluorite with Celestite - Classic USA locale
stock #SOLD 8.AE-886
Clay Center, Ottawa County
Ohio, United States
3.7 x 3.3 x 2.3 CM (small miniature/ large thumbnail (toenail))
price: $0
Late Summer 2021

Sharp, lustrous "root beer" color Fluorites from the famed old finds at Clay Center Ohio. The Fluorites are zoned, the outer edges are glass clear with a hint of yellow color and the centers a cloudy deep orange brown. Vividly fluorescent and in excellent condition, there is minor Celestite present as small white blades.
