Hemimorphite on Goethite
Mina Ojuela, Mapimi
6.8 x 5.6 x 3.1 CM (cabinet)
new year 2021
Remarkable esthetics, a bright white radiating cluster of bladed Hemimorphite crystals set in a sculptural Gossan matrix. The matrix is quite unusual being a series of concentric half spherical voids or cups which are all empty except one with the flower-like spray perched in the center. There has been thousands of Hemimorphite specimens found over the years at Mina Ojuela, it takes something very special to stand out in the crowd. This is such a piece with excellent form and bright luster on the Hemimorphite blades.
Richly colorful mix of copper species featuring large masses of hairy Cyanotrichite. Classic Arizona specimen with rich blue and green hues. In addition to the listed species there are several other micro crystals including what looks like very tiny Spangolites, but that is just a guess and they are very small, hard to see well even at 40X magnification. No matter the main event is the hairy masses and mats of Cyanotrichite. Ex Hitchings collection, this was purchased by him in 1984.
Purple Smithsonte is very uncommon worldwide, the best source was this small deposit in Sinaloa that has not produced much of any quality for several years. This is an older specimen with a nice velvet sheen on a botryoidal surface that gives a rather wet looking luster. This Smithsonite grades in color from a darker purple to more pink areas with some nice color mottling. Choix Smithsonites are still much lower in cost than almost any other locale, they are an excellent value yet often equally attractive. The color is what sets this piece apart, a choice addition to any Smithsonite or Mexican suite.
SOLD Rutile - twinned crystal cluster
stock #SOLD 20.1-758
Gamsberg, Windhoek Rural
3.5 x 1.7 x 1.3 CM (small miniature/ large thumbnail (toenail))
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.
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
Minerva Mine #1, Rosiclare Level, Cave in Rock
4.1 x 3.8 x 3.1 CM (miniature)
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
7.3 x 5.8 x 4.2 CM (cabinet)
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
Getchell Mine, Adam Peak, Potosi Mining District, Humboldt County
4.8 x 3.7 x 2.2 CM (miniature)
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.
