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.

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.

Hemimorphite - intense blue
stock #21.1-009
Sa Duchessa Mine, Oridda Valley, Domusnovas, South Sardinia Province
Sardinia, Italy
4.2 x 2.7 x 1.7 CM (miniature)
price: $180
new year 2021

A small but vivid blue Hemimorphite with a sparkling luster from the classic Sa Ducessa Mine. In fine condition save at the outer edge where this was removed the display side is perfect and undamaged. This is a fairly old specimen (over 25 years at minimum) and since the color is still excellent it seems to be fully color stable. The deeper blue grades to a lighter powder blue on some of the botryoids. Unlike the recent fake Hemimorphites from Mexico which were a darker blue this is full natural and a nice example from this famed locale.

Pyromorphite
stock #8.AE-1059
Broken Hill, Yancowinna County
New South Wales, Australia
7.3 x 6.1 x 2.8 CM (cabinet)
price: $330
new year 2021

Bright yellow-green crystals of Pyromorphite on a contrasting manganese oxide matrix. In excellent condition overall, the previous label calls the matrix Galena, but this is incorrect. Broken Hill is perhaps the most famed, classic Australian mineral locale. Many types of Pyromorphite have been found there over many years, most being a distinctive brown or white color. The yellow, and especially the green colors, are more rare and sought after.

Agate nodule - (Laguna) - polished pair
stock #21.1-007
Ojo Laguna, Estacion Ojo Laguna, Municipio de Ahumada
Chihuahua, Mexico
4.6 x 4.3 x 2.8 CM (half) (miniature)
price: $260
new year 2021

A complete nodule of bright banded Agate with especially vivid coloring. Excellent contrast with strong pinks, yellows and light violet banding mixed with white zones. These have a complete undamaged rim. Laguna Agates have become prized since they can have such unusual hues and rich coloring. This is a nice small nodule very reasonably priced for the quality.

Beryl var. Aquamarine
stock #20.1-341
Governador Valadares, Doce Valley
Minas Gerais, Brazil
2.7 x 2.2 x 1.5 CM (thumbnail)
price: $90
new year 2021

A clean and very lustrous gem crystal with a well-defined form. An older Brazilian piece with an unusual habit that is quite different from the typical elongated hexagon. Not super perfect under close inspection as there are some tiny edge nicks, but this still looks fine and has nice color, transparency and crystal form.

Neptunite with Benitoite on Natrolite
stock #AC-368
San Benito Peak, San Benito County
California, United States
10.6 x 6.4 x 5.7 CM (cabinet)
price: $490
new year 2021

Cabinet sized matrix specimen covered with a dense mass of lustrous black Neptunite on the display face. A single blue Benitoite is tucked away in the mix so this is really all about the Neptunites. Several crystals are doubly terminated and all contrast well with the white matrix. This is an older piece from the Immer Cook collection, dating to the late 1960 era. Choice piece with the Neptunite well-exposed and displaying very well.
