Cavansite on Stilbite
stock #21.1-283
Wagholi Quarries, Wagholi, Pune District
Maharashtra, India
4.4 x 3.9 x2.2 CM (miniature)
price: $380
Late Summer 2021

Esthetic clusters of bright blue spheres of Cavansite crystals on contrasting creamy white stilbite. Cavansites from Wagholi are fairly common on the mineral market but very clean, brilliant and esthetic pieces are less common. As the quarries are shut down they have been getting much less available. Cavansite has the most vivid color of all the Traprock minerals, a bright Cavansite is a nice addition to any collection. This piece has individual balls to 1.8 CM, but most are clustered together forming a chain of spheres. The blue is in two different tones and one sphere is broken open so the radial structure is easily seen. This offers several good display angles. In fine condition with great luster, sparkle and color.

Apophyllite with Prehnite
stock #AX-7-185-(832)
Luck Stone Quarry, Bealton, Fauquier County
Virginia, United States
4 x 3.3 x 1.6 CM (miniature)
price: $120
Late Summer 2021

An older Virginia (USA) Apophyllite with crystals nearly covering a thin Prehnite matrix. This locality is not as well-known as some of the other Quarries in this region, and thin habit of Apophyllite is very unusual as well. The wide faces of the crystals are lightly frosted with druzy Apophyllites while the thinner faces are transparent, glassy and smooth.

Chrysocolla after Malachite after Azurite with Wulfenite, Goethite.
stock #8.AE-1073
Whim Creek Copper Mine, Whim Creek, Roebourne Shire
Western Australia, Australia
11.7 x 6.3 x 4.6 CM (cabinet)
price: $780
Late Summer 2021

Crystallized Azurite rosettes replaced by Malachite which is partly to fully replaced by Chrysocolla. A modern classic find from Whim Creek, this is an especially choice specimen with a stout stalactitic Goethite matrix. A few small Wulfenite crystals are also noted on the matrix as are more recent tiny balls of Malachite. In fine condition. The rosettes vary in color from blue-green to green and are in both clusters and isolated balls. All the rosettes display very good crystal forms that faithfully show the original Azurite structures. These were found over 30 years ago and often in cabinet sized specimens. A modern classic.

Fluorite on Quartz
stock #AX-14-347
Orange River, Namakwa
Northern Cape Province, South Africa
3.6 x 1.4 x 1.3 CM (thumbnail)
price: $145
Late Summer 2021

A cute thumbnail with transparent, colorless Fluorites that have vivid purple cores or phantoms. These are all clustered on two faces of a clear Quartz crystal. The Quartz and the Fluorites are in fine condition. From a find about 4 years ago in the Orange River region (South Africa) this is just barely a thumbnail but will fit in a perky box.

Amethyst - radiating cluster
stock #17.1 099
Cerro de Concordia, Piedra Parada
Veracruz, Mexico
5.1 x 5 x 2 CM (small cabinet/ large miniature)
price: $190
Late Summer 2021

Flawless, gemmy and highly lustrous, a simple cluster of Veracruz Amethyst formed by doubly terminated crystals. In exceptional condition there are a few small bits of adhering matrix but overall this is just Amethyst. This locality is unique in the world for look and quality of the Amethyst. These represent a great value in the mineral world. The arrangement of these crystals in a star cluster is also a hallmark of the Piedra Parada zone. It is almost impossible to appreciate fully the glass-like nature of this specimen in photos.

SOLD Cerussite included by Chalcotrichite
stock #SOLD 21.1-278
Tsumeb
Otjikoto Region, Namibia
4.6 x 3.7 x 3.1 CM (miniature)
price: $0
Late Summer 2021

One of the most sought after Tsumeb minerals is Cerussite that has inclusions of Chalcotrichite that turn clear crystals red or orange. The most vivid examples tend to be very small crystals and incredibly costly. This is a choice Cerussite that has Chalcotrichite needles, both on the exterior and interior, however the color not super saturated but is a light reddish-orange. The crystals reach over 3 CM which is large for an included Cerussite, and are quite well-defined with obvious twinning. Several faces are rather jagged looking on close exam where is seen geometric stepped crystal patterns some of which have formed around needles of Chalcotrichite. The matrix is a mixture of Dolomite, Malachite, Calcite and there are some unidentified dark acicular crystals at the junction of the Cerussites with the matrix. The Cerussites are transparent and the faces are highly lustrous and glass-like. Looks fine from several angles, the main crystals are in fine condition with perfect tips. The backside has some minor broken areas but it is only on the back and not seen from the front which is in excellent shape. A hard to get Tsumeb rarity that is better looking in person too.

Dechenite (As-Descloizite) with Vanadinite - vintage specimen
stock #21.1-236
Kappel, Ferlach, Karawanken
Carinthia, Austria
4.4 x 3.5 x 1.2 CM (miniature)
price: $220
Late Summer 2021

A fine and uncommon example of the As variety of Descloizite known as Dechenite with several vintage labels. The front surface of this specimen is densely covered with sparkling crystals of red orange As-Descloizite. The crystals are quite elongated and most are in fine condition as well. Old labels are included from Julius Bohn (Vienna, dealership begun in 1884), W Mauncher (Munich 1870-1930) and an unattributed Italian. Choice, historic and unlike "normal" Descloizite!

Franckeite var. Potosiite - exceptionally well-crystalized
stock #7.AE-193
San Jose Mine, Oruro
Oruro Department, Bolivia
7.9 x 4.1 x 3.8 CM (cabinet)
price: $2400
Late Summer 2021

Franckeite has always been an incredibly rare mineral and was only known in micro crystals until the major find in 2004 of what was then called Potosiite. This is now known to be a variety of Franckeite with less tin than usual. This was not a large find but the better specimens were quickly gobbled up by collectors and are almost never available now. This piece was one of those major specimens, it is from a collection we are liquidating for the owner and retains the original Kosnar label. In incredible condition for this delicate mineral with individual crystals that reach over 1 CM, in clusters and free standing masses. This piece also has crystals of the original Franckeite that is not the Potosiite variety so this brings two of the world's rarest Sulfosalts on a single matrix. For the species, this is also an esthetic piece, with very three dimensional form and a good metallic luster.
