SOLD Rutile - twinned crystal cluster
stock #SOLD 20.1-758
Gamsberg, Windhoek Rural
Khomas Region, Namibia
3.5 x 1.7 x 1.3 CM (small miniature/ large thumbnail (toenail))
price: $0
new year 2021

A complex cluster of Rutile crystals showing both double termination and twinning. One termination is the more complex hoppered type. From Gamsberg near Windhoek, this was a small but impressive find about 20 years ago. In good condition with some minimal edge bruising, bright luster and very sharp striations. This is well above average quality for this find and an attractive, uncommon Namibian Rutile.

SOLD Fluorite - red, classic Swiss
stock #SOLD 20.FC-086-(003B)
Goscheneralp, Goschenen Valey
Uri, Switzerland
7.3 x 6.2 x 4.2 CM (cabinet)
price: $0
new year 2021

An outstanding, old, true red Alpine Fluorite. While pink Fluorites are prized finds from the Alps of France and Switzerland, the darker pink and red Fluorites are the most treasured, and very rare. Typically, these red Fluorites have a somewhat "melted" look with a silk luster and rounded edges, which can make some of the crystals seem crude. This piece is much more distinct than usual with clearly developed Octahedral crystals that are translucent to transparent, frosted and a vivid red color. With backlighting the red is especially intense and glows like red glass. The first 3 photos here are not backlit so the color is as this will appear in a normal display. The last image has a small amount of backlighting and the color is more vibrant as a result. With a well-placed backlighting the look is exceptional. Ex Valentin Sicher collection, from the classic Goscheneralp in the Uri Canton of Switzerland, the main crystal is 5.6 CM across. We are told this is a very old piece but we have no way to confirm the date of discovery, it does however look "vintage". In fine condition damage-wise, there are some old recrystallized contacts (mostly on the backside) and face frosting but no bruising. The matrix is a nice contrast being a crystalline mix of Albite and Quartz. There are some excellent display angles and there is a "backside" that is less defined and thus less attractive but still with a great red color. Excellent addition for any serious collection of fine Fluorites or Alpine minerals.

Fluorite - USA classic locale
stock #20.1-919
Minerva Mine #1, Rosiclare Level, Cave in Rock
Illinois, United States
4.1 x 3.8 x 3.1 CM (miniature)
price: $320
new year 2021

A crisp blue Fluorite from the Minerva Mine, Cave in Rock, Illinois. This specimen hosts a small cube that is perfectly transparent and has a tiny wisp of purple color seen only on one face. The larger cube has a milky yellow core and a pale blue edge. The specimen is not perfect with some contacts and bruising but this still looks fine from some angles. The color of the sharp transparent cube is quite choice for the locale. Gemmy blue Fluorite is one of the more desired and sought after Southern Illinois Fluorites. Ex L Sweetman collection, this is a 1950-mid 60's era specimen and it does look different from the finds of the eighties and 90's.

Corkite on Plumbogummite and Goethite
stock #20.1-900 (ZS-CRK4099)
Serra Da Mina Mine, Cercal do Alentejo, Santiago do Cacem
Setubal, Portugal
7.3 x 5.8 x 4.2 CM (cabinet)
price: $1350
new year 2021

Corkite is a rare Lead Phosphate mineral related to Beudantite that is just never seen as display specimens. Most are micromounts where the tiny crystals can be mesmerizing. This piece is something else, a full cabinet sized top grade specimen with hundreds of gemmy Corkite crystals sparkling in an esthetic iridescent display. The matrix is a blue green to orange Plumbogummite and a chatoyant botryoidal Goethite which sets the Corkite off nicely. The Corkite crystals are sharp, glassy transparent in colors of brown, orange and blue that come alive under magnification. These are up to about 1 mm in size and most are well isolated, yet still densely covering the matrix. I have never seen another Corkite specimen that can be displayed and appreciated as an esthetic and very colorful piece in a mineral cabinet.

Getchellite with Realgar and Orpiment
stock #20.1-918
Getchell Mine, Adam Peak, Potosi Mining District, Humboldt County
Nevada, United States
4.8 x 3.7 x 2.2 CM (miniature)
price: $130
new year 2021

The rare specie Getchellite from the type locality in Nevada, USA. Brilliant red masses and crude crystals mixed with orange Realgar and yellow Orpiment. Ex Ruth and Andy Palmer specie collection and study suite for Dr. Joe Mandarino. The Getchellite here is in eye visible dark red clusters and masses. Strong magnification shows a few crude crystal faces as well as cleavages in the colorful mix. Rich specimen of a quite rare but colorful mineral.

Barite (Baryte) with Realgar phantoms - classic locale
stock #20.1-887
Baia Sprie
Maramures, Romania
5.2 x 4.2 x 1.7 CM (small cabinet/large miniature)
price: $1750
new year 2021

A superb and very hard to find Barite with the sharp color zoning of red to orange Realgar inclusions that makes remarkable phantoms. This classic mine has been closed now for a long while, there will never be more of these and there were never many. Most of the Realgar included Barite found was not so transparent and the red color filled the entire crystal. This piece has excellent clarity and the inner zoning is very sharp and well-defined. Overall in fine condition for such thin and delicate crystals, these are also far larger and better isolated than most crystals. There are very small rough areas as seen in the photos but this is never the less a superb display specimen, and a standout in any suite of Barites.

Natanite on Ilvaite
stock #20.1-893-(ZS-NTN4126)
El Potosi Mine, Level 10, Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
2.9 x 2.2 x 2 CM (thumbnail)
price: $440
new year 2021

A superb gemmy crystal of Natanite on an Ilvaite matrix. Natanite is a very rare Tin specie, almost never seen for sale. The very best specimens came from this one time find at the Potosi Mine in Santa Eulalia, and this is a choice example of that find. Nestled in the Ilvaite crystals on this thumbnail thumbnail is a single transparent to translucent red octahedra than is just under 2mm in size. Ex Peter Megaw and Terry Szenics collections. This sort of specimen is certainly not a "mainstream" mineral so it is not for everyone, but a treasure for a serious specie collection or a suite of rare Mexican minerals.

SOLD Anorthite - gemmy crystals, type locality
stock #SOLD 20.1-689
Monte Somma, Somma-Vesuvius complex, Naples
Campania, Italy
5.9 x 4.7 x 2.8 CM (cabinet)
price: $0
new year 2021

Transparent colorless crystals of Anothite are nestled in a shallow vug. An old specimen (three old European labels accompany this) from Monte Somma the type locality for the specie. The crystals are up to 5 mm though most are smaller. In excellent condition with no visible damage, this is great under magnification as the sharp, glassy crystals have very bright luster.
