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.
Natanite on Ilvaite
El Potosi Mine, Level 10, Santa Eulalia, Aquiles Serdan
2.9 x 2.2 x 2 CM (thumbnail)
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.
Cabrerite (Magnesian Annabergite)
Kamariza Mines, Aglos Konstantinos, Laviron Mining District, Lavreotiki
6.4 x 5.5 x 4.7 CM (cabinet)
new year 2021
Colorful crystals of Cabrerite from the famed mines of Laviron. This rare variety of Annabergite is usually found as micro crystals up to about 2mm. These crystals are still small but reach 6mm so they are huge for this variety. Several sprays, vugs and masses are scattered on the matrix, most are associated with scalenohedral Calcites.
A very nice, old (1895) English specimen with fine provenance. This is from the famed Wallace Gould Levison collection. His label on the specimen is intact and we will include a photocopy of the page from his collection ledger which indicates he received this from F L Smith on December 7th, 1895. The specimen has blue, green, white and yellow colored Allophane masses. This is every color I know of for Allophane, all on one specimen. Colorful small botryoidal and stalactitic masses best appreciated with good magnification. Allophane is not currently listed by Mindat from Tavistock but it is well-known from the West Devon area. This piece is very high quality. Outstanding historic and colorful UK specimen.
