Cabinet sized matrix specimen covered with a dense mass of lustrous black Neptunite on the display face. A single blue Benitoite is tucked away in the mix so this is really all about the Neptunites. Several crystals are doubly terminated and all contrast well with the white matrix. This is an older piece from the Immer Cook collection, dating to the late 1960 era. Choice piece with the Neptunite well-exposed and displaying very well.
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 Fluorite - USA classic locale
stock #SOLD 20.1-919
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.
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.
