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.

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.

SOLD Dechenite (As-Descloizite) with Vanadinite - vintage specimen
stock #SOLD 21.1-236
Kappel, Ferlach, Karawanken
Carinthia, Austria
4.4 x 3.5 x 1.2 CM (miniature)
price: $0
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.

Scheelite on Muscovite
stock #6.2-899
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan Province, China
4.3 x 3.4 x 3 CM (miniature)
price: $880
Late Summer 2021

Outstanding miniature with a sharp and glassy Scheelite crystal nestled in Muscovite blades. The Scheelite is translucent to transparent and has the sought-after orange color. There is no damage or chipping but there is some cracking to note near the base which have been stabilized. This is not distracting or easy to find without some magnification. The price has taken this into account. Good Scheelites with fine color have become costly, larger specimens of this quality are often well into the 5 figures. This piece was collected in 2005 while the small mines on the higher reaches of Mt. Xuebaoding were active. More recent finds from Pingwu are found at lower elevation and mostly are a light yellow to brownish. A pretty modern classic.

Fluorite
stock #21.1-339
Cantera Llamas, Duyos, Caravia
Asturias, Spain
2.9 x 1.8 x 1.8 CM (thumbnail)
price: $480
Late Summer 2021

A pair of edge modified cubes of transparent Fluorite in an esthetic cluster. The condition is incredible with textbook perfect form, the color a light violet and the one crystal is tabular. An excellent large thumbnail, it is hard to capture the clarity and form in photos, in person it is especially impressive. The faces appear glass-like and smooth at first but on close inspection with good lighting the surfaces are covered with tiny geometric growth structures. A few very tiny Fluorite cubes are perched on this as well, and there is a shard of snow-like Quartz matrix that adds a nice sparkle. Aside from a small cleave on the underside of the lower crystal (not visible on display) this is perfect from all points of view, competitive quality.

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.
