17560:
Pentagonite
Wagholi Quarries, Wagholi, Pune District, Maharashtra, India
Small cabinet - 6.5 x 3.2 x 2.4 cm (2.6 x 1.3 x 0.9 inches)
Specimen status: Sold

The ridge of a mound of typical Deccan basalt matrix is carpeted with tiny, colorless, transparent heulandite crystals. But the star here is the deep blue, 1.5 cm tuft of pentagonite crystals slightly offset from center. The pentagonite is slightly contacted, but not an issue for this species at this price. Sits well for display on the sawn base. (The basalt is very tough, so a sawn is the most efficient method to extract specimens without damage.) Three years ago Indian mineral wholesalers reported that the cavansite-producing quarries are either worked out, flooded, or otherwise abandoned, and the cavansite/pentagonite supply is now only a trickle of what it was on the past, with no immediate hopes for more production.







17572:
Cavansite and Calcite - $75
Wagholi Quarries, Wagholi, Pune District, Maharashtra, India
Cabinet - 10.3 x 8.7 x 5.5 cm (4.1 x 3.4 x 2.2 inches)
Specimen status: Available     Send email to order

A concave cavity in basalt matrix hosts a string of beautifully deep blue cavansite sprays. These sprays reach 1.8 cm wide. Accented with a few small calcite rhombs, and on a carpet of tiny, sparkling heulandite crystals. Minor damage to one of the cavansite sprays, but not a significant detraction. A crack running through the matrix has been stabilized. Three years ago Indian mineral wholesalers reported that the cavansite-producing quarries are either worked out, flooded, or otherwise abandoned, and the cavansite/pentagonite supply is now only a trickle of what it was on the past, with no immediate hopes for more production.




17573:
Pentagonite - $75
Wagholi Quarries, Wagholi, Pune District, Maharashtra, India
Cabinet - 12.4 x 9.3 x 4.1 cm (4.9 x 3.7 x 1.6 inches)
Specimen status: Available     Send email to order

A beautiful deep blue pentagonite spray sits at the bottom of a sparkling, heulandite-lined basalt cavity. The pentagonite cluster is 2.4 cm wide, with one single needle reaching 1.4 in length! One pentagonite cluster top has been lopped off, but this is only a distraction under magnification. Three years ago Indian mineral wholesalers indicate that the cavansite-producing quarries are either worked out, flooded, or otherwise abandoned, and the cavansite/pentagonite supply is now only a trickle of what it was on the past, with no immediate hopes for more production.




17702:
Azurite, Arsentsumebite, and Cerussite - $400
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia  Type locality for arsentsumebite
Small cabinet - 8.5 x 5.4 x 3.8 cm (3.3 x 2.1 x 1.5 inches)
Specimen status: Available     Send email to order

Multiple surfaces are covered with a deep blue, lustrous azurite carpet, in which individual azurites reach 7.8 mm. Most of the azurites are elongated and platy but a few are blocky. Scattered about the azurites -- and provided wonderful color contrast -- are patches of green, microcrystalline arsentsumebite. Opaque to transparent cerussites, topping out at 4 mm, are also present. A Tsumeb classic, and in excellent condition. Displays quite nicely.







17773:
Scheelite - $125
Mt Xuebaoding, Pingwu County, Mianyang Prefecture, Sichuan Province, China
Small cabinet - 7.2 x 6.9 x 4.1 cm (2.8 x 2.7 x 1.6 inches)
Specimen status: Available     Send email to order

A rather large and lustrous, transparent to opaque scheelite crystal cluster. The longest individual crystal edge is 4.1 cm. Minor muscovite and calcite are noted. (The scheelite-calcite occurrence is pretty uncommon at this locality.) As is typical for scheelite from locality, the specimen has strong blue-white fluorescence under shortwave UV. A little edgewear is noted, but overall in very good condition.







17801:
Calcite - $200
Iraí, Alto Uruguai region, Rio Grande do Sul, Brazil
Cabinet - 12.5 x 7.8 x 6.6 cm (4.9 x 3.1 x 2.6 inches)
Specimen status: Available     Send email to order

A large and quite handsome calcite group, Mostly translucent with a very pale pink color. Strong pinkish fluorescence under both longwave and shortwave UV. Entire specimen is pristine; no damage is noted. The curved matrix at the base provides a very nice accent, but needs a stand to be displayed vertically.




17959:
Copper
Arcadian Mine, Ripley, Houghton County, Michigan
Large cabinet - 10.9 x 6.4 x 4.4 cm (4.3 x 2.5 x 1.7 inches)
Specimen status: Sold

A roughly crystalline copper mass with nice patina rises above the apex of a color-matched matrix. The matrix has a flat base (not sawn) and provides a beautifully natural stand, making for excellent presentation. No damage.







17968:

Kröhnkite

Chuquicamata Mine, Chuquicamata District, Calama, El Loa Province, Chile - Type locality for kröhnkite
Small cabinet - 7.1 x 2.4 x 0.9 cm (2.8 x 0.9 x 0.4 inches)
Specimen status: Sold

A beautifully blue and translucent specimen of kröhnkite, which is a very uncommon hydrated sodium copper sulfate, Na2Cu(SO4)2 . 2H2O. Composed of many parallel crystals. Usually not seen in specimens this large. When this update was prepared, only one other specimen was found for sale; it is only 3.8 cm and priced at $1,200. Not terminated (as is typical for the species) but otherwise nothing I'd call damage. Add a splash of blue to your mineral cabinet!







17974:
Calcite and Marcasite - $100
Brushy Creek Mine, Viburnum Trend District, Reynolds County, Missouri
Small cabinet - 8.4 x 5.7 x 4.6 cm (3.3 x 2.2 x 1.8 inches)
Specimen status: Available     Send email to order

A Viburnum Trend classic! A cluster of sharply-crystallized and pristinely terminated, gray calcite scalenohedra hosts a covering of sparkling marcasite on selected crystals of the cluster. The calcites reach 3.3 cm in height. Hard to find a good, affordable example these days. Sits perfectly for display on its naturally flat base. No damage.







17976:
Manganoan Calcite and Quartz - $300
El Mochito Mine, Santa Bárbara Department, Honduras
Cabinet - 10.3 x 7.0 x 6.2 cm (4.1 x 2.8 x 2.4 inches)
Specimen status: Available     Send email to order

Pleasantly pretty pastel pink manganoan calcite 'fuzz' fills much of the cavity formed by several terminated quartz crystals. Sparkly and very pink, with interesting texture and aesthetics. Fuzzy! Pink! Accented with a few small patches of quartz druze. No damage. This will certainly add a splash of color to your display cabinet. Did I mention it's pink?







18058:
Calcite and Fluorite
Cave-in-Rock Sub-District, Illinois-Kentucky Fluorspar District, Hardin County, Illinois
Cabinet - 9.4 x 5.6 x 4.9 cm (3.7 x 2.2 x 1.9 inches)
Specimen status: Sold

A matrix of blue and yellow fluorite hosts a thick forest of opaque, white calcite needles. The calcites reach 2.2 cm in length. The majority are sharply terminated although a few scattered crystals are incomplete. Sits well for display as shown without needing a stand.







18187:
Quartz (variety Smoky Quartz) - $40
Xianghualing Mine, Linwu County, Chenzhou Prefecture, Hunan Province, China
Small cabinet - 8.0 x 4.7 x 4.3 cm (3.1 x 1.9 x 1.7 inches)
ex Gene Reynolds collection
Specimen status: Available     Send email to order

A cluster of transparent, lightly smoky quartz crystals from an unexpected locality. The largest individual crystal extends 4.3 cm from root to termination. A little termination microchipping present.
