Neptunite with Benitoite on Natrolite
stock #AC-368
San Benito Peak, San Benito County
California, United States
10.6 x 6.4 x 5.7 CM (cabinet)
price: $490
new year 2021

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
stock #18-AX-035
Mina Ojuela, Mapimi
Durango, Mexico
6.8 x 5.6 x 3.1 CM (cabinet)
price: $330
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.

Smithsonite - purple to pink
stock #20.1-922
Choix, Municipio de Choix
Sinaloa, Mexico
7.3 x 5.1 x 3 CM (cabinet)
price: $290
new year 2021

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.

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.

Allophane - historic, classic locale
stock #AX-35-050-(2695)
Tavistock, West Devon
Devon, England
6.5 x 5 x 1.8 CM (cabinet)
price: $380
new year 2021

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.
