Fluorite
stock #15.1-032
Elmwood Mine, Carthage
Tennessee, United States
4.7 x 3.9 x 2.9 CM (miniature)
price: $90
new year 2021

A dark purple to purple blue Fluorite from the Elmwood Mine that has some zoning and is fairly transparent. A nice colorful Fluorite that glows well when backlit. So much USA Fluorite has become very expensive, this is an affordable specimen in very good condition from this classic USA locale.

Diopside
stock #15.1-674
Orford Nickel Mine, St-Denis-de-Brompton, Estrie
Quebec, Canada
4.3 x 1.3 x .9 CM (miniature)
price: $190
new year 2021

A terminated glassy crystal of Diopside with nice green color on the top. Transparent to translucent, this was in the Warren Johannson collection, a very nice example of a "Nickel" Diopside. There were some large and well-known pale brown crystals found at one time in this locality but very few such complete green crystals. A Canadian classic.

Pyrargyrite (Ruby Silver crystals)
stock #AX-29-047
San Juan de Rayas Mine, Municipio de Guanajuato
Guanajuato, Mexico
2.8 x 2.7 x 2 CM (thumbnail)
price: $380
new year 2021

Super lustrous, metallic crystals of Pyrargyrite in a cluster with no matrix. Many of the larger crystals are distinctly twinned. These look silvery-black without very strong lighting but a few edges show the bright red flash and glint of the "ruby" color. The crystals are opaque for the most part but a few edges show some translucence. A mid 1980 vintage Silver secondary specie from the famed and prolific San Juan de Reyes Mine (Guanajuato, Mexico). A hefty thumbnail in good condition, there is some roughness and the backside is the point of removal but this is still in better shape than usual for this delicate mineral. The Ruby Silvers of Mexico are now considered classics and are quite different than the old European specimens. Choice.

Mimetite with Goethite
stock #20.1-289
Preguica Mine, Sobral da Adica, Moura
Beja, Portugal
7 x 3.7 x 3.8 CM (cabinet)
price: $250
new year 2021

From Portugal, a very well-crystalized, delicate specimen of Mimetite from a locality we do not see often, but which is certainly an important deposit. Mimetite crystals are dense but well separated on all sides of this matrix with both yellow and orange colors. The matrix is a mix of bluish-black manganese oxides and Goethite which makes an excellent contrast for the Mimetites. Despite the obvious delicacy this is in excellent condition and the matrix seems to be quite solid and stable. Excellent addition for any suite of Lead secondaries, this is a very choice example from Preguica. Clearly unlike Mimetite specimens from any other locality.

Chrysocolla - drusy
stock #21.1-010
Inca De Oro, Chanaral
Atacama Region, Chile
6.3 x 3.6 x 1.6 CM (cabinet)
price: $250
new year 2021

Bright blue and with a sparkling druse of Quartz over the display face. Sawn on back it seems this was being fashioned into a jewelry item but was left unfinished. Displays well and the color is an excellent blue, with some green hues seen under strong lighting. The Chrysocolla finds from Chile was a major source of fine specimens for many years. These are no longer available and they have begun to increase in price quickly for choice pieces.

Barite (Baryte) - classic USA locale
stock #8.AE-786
Stoneham, Weld County
Colorado, United States
5.5 x 2.6 x 1.4 CM (cabinet)
price: $130
new year 2021

A single Barite crystal at the base that diverges into two slightly offset crystals with separate terminations at the end. In excellent condition, a classic Stoneham, Colorado Barite with zoned blue color. Translucent to transparent with no damage. The better Stoneham Barites are some of the best values of crystallized USA specimens.

Pyromorphite on Malachite
stock #0589-JM-3764
Brown's open pit, Rum Jungle
Northern Territory, Australia
9.5 x 4.7 x 4.2 CM (cabinet)
price: $480
new year 2021

An older Rum Jungle specimen (1970 vintage) that is quite different and with far more vivid color than recent specimens. Ex. John H. Marshall collection, this has very lustrous bright green Pyromorphites and some small brown crystals as well. The Malachite is almost invisible on the front face except in a few nooks, it is much more well-defined on the back and sides where it forms fibrous crystals.

Bustamite, Calcite, Sphalerite, Chalcopyrite etc.
stock #13.1-283
Broken Hill, Yancowinna County
New South Wales, Australia
2.1 x 1.8 x 1.3 CM (thumbnail)
price: $90
new year 2021

A cute thumbnail with the focus being one larger crystal of Bustamite. The specimen also includes some very tiny Spessartine as well as the Sulphides listed above. The Bustamite has the typical crude or melted look on some edges but is distinctly terminated and well-defined. Broken Hill is a famed locality that is on every short list of world class deposits and is certainly a classic.
