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.

HOLD Libethenite, Sieleckiite and Turquoise
stock #HOLD 8.AE-1050
Mt Oxide Mine, Mount Gordon, Gunpowder District, Mt Isa - Cloncurry area
Queensland, Australia
6.5 x 3.2 x 1.7 CM (cabinet)
price: $300
new year 2021

Fine micro-crystals covering several surfaces. Most prominent are well-formed dark green Libethenite that contrast with a pale blue Turquoise that has mostly encrusted some darker blue Sieleckiite. Ex Marty Zinn collection, with his label, this is a sizable piece from this interesting locality. Sieleckiite is a very rare specie and this is the type locale; it is only known from three places on the planet, and very few specimens exist. It is important to note that the Sieleckiite is partly to fully covered by the Turquoise and perhaps also some Variscite so it is not very distinct. Still a fine mix of attractive and rare minerals, best appreciated with magnification, yet sizable enough to be in a display.

Pyromorphite on Malachite
stock #21.1-008
Brown's open pit, Rum Jungle
Northern Territory, Australia
5.8 x 4.1 x 1.7 CM (cabinet)
price: $650
new year 2021

A fine example of Rum Jungle Pyromorphite with sharp and well-defined crystals set on a darker Malachite matrix. The Pyromorphite on this specimen is so dense that the Malachite is almost fully hidden and is only visible through small gaps and on the edges. In excellent condition, the color and luster are better in person too. This remarkable locality has been flooded for some time now, this piece is from the last successful specimen extraction, and is a super example of top quality from the "Pizza Pocket".

Cassiterite on Quartz
stock #8.AE-1048
Elsmore Tin Mine, Elsmore, Gough Co.
New South Wales, Australia
9.1 x 8.2 x 5.7 CM (cabinet)
price: $1850
new year 2021

An exceptional specimen of top quality gemmy Cassiterite crystals scattered on a wide Quartz crystal. A classic Australian locale where mining began in 1871, this piece is the best I have seen personally and is a fine Cassiterite from any place. The crystals all show twinning, some are contacted but not broken, and all are super lustrous. Crystals are up to 2.3 CM across. The Quartz crystal is broken and contacted on the backside, the front has some edge contacts and rough areas but nothing distracting from the bright Cassiterites. These look black without strong light, but when well lit, they are a golden brown color, translucent to transparent and contrast well with the Quartz matrix.
