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.

Cabrerite (Magnesian Annabergite)
stock #20.1-917
Kamariza Mines, Aglos Konstantinos, Laviron Mining District, Lavreotiki
Attica, Greece
6.4 x 5.5 x 4.7 CM (cabinet)
price: $140
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.

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.

Faujasite with Augite in Limbergite matrix
stock #20.1-916
Sasbach, Kaiserstuhl, Baden
Baden-Wurttemberg, Germany
5.3 x 4.2 x 3.8 CM (cabinet)
price: $50
new year 2021

An old specimen of this rather scarce Zeolite specie from the most prolific locality at Sasbach, Germany. Many small cavities on all sides hold white linings of tiny Faujasite crystals and botryoidal masses. The crystals are typically very tiny octahedra best seen with good magnification. Some small Augite crystals are also present. This is not an "esthetic" specie with crystals typically under 1 mm, but this is a good example none the less. Ex. R and A Palmer collection from the Joe Mandarino study suite.

Quartz replacing and coating Glauberite
stock #20.1-883
Irai, Alto Urugual region
Rio Grande do Sul, South Region, Brazil
4.8 x 3.1 x 1.4 CM (miniature)
price: $80
new year 2021

From the zone in Brazil famed for Amethyst geodes, this is something very different from almost any other Quartz. A pair of spindle-like growths of Glauberite that has been altered to and overgrown by Quartz. These are perfect, complete all around, with tiny transparent smokey Quartz sparkling on all sides.

stock #AX-16-232
Jeffrey Mine, Asbestos
Quebec, Canada
3.5 x .6 x .7 CM (small miniature/ large thumbnail (toenail))
price: $300
new year 2021

A single glassy prism of yellow-green Vesuvianite from the great Jeffrey Mine. In perfect condition sections are gem clear, transparent and other parts are translucent with wispy internal veils. One edge of the prism has a dusting of tiny transparent Vesuvianites that are nearly colorless. Somewhat dichroic, this more yellow hue is much less common than the more apple green colors. The Jeffrey Mine produced many fine Vesuvianites, certainly the world's best but also was the source of many rare and unique colors. This is a nice and relatively affordable crystal, impressive for the size and nicer in person.

Lemanskiite with Lammerite and Olivenite
stock #20.1-901-(ZS-LEM4260)
El Guanaco Mine, Guanaco Santa Catalina, Antofagasta Province
Antofagasta Region, Chile
5.5 x 4 x 3.8 CM (cabinet)
price: $320
new year 2021

A rich showing of crystal clusters of the rare copper specie Lemanskiite from the type locality. Lemanskiite is a fairly new mineral recognized as unique in 1998. This piece also has a sizable ball of crystallized Lammerite (about 9 mm across) and a few sprays of Olivenite as well. The Lemanskiite is in micro crystals up to 2 plus mm radiating clusters that can be seen as distinct crystals by naked eye, but under magnification these are super impressive. This is a choice specimen of both Lammerite and Lamanskiite.

Barite - sugarcube habit
stock #20.1-895-(ZS-QTZ4127)
Murray mine, Sugarbowl pocket, Independance Mts. District, Elko Co.
Nevada, United States
3.4 x 2.6 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $140
new year 2021

Brilliant sparkling thumbnail to toenail with excellent form. A modern USA classic, this is a cluster of blocky Barites (Barytes) that are well covered with a druzy Quartz. Highly lustrous, this looks just like sugar cubes. From the one time find more than 20 years ago at the Murray Mine(Elko, Nevada, USA) from a remarkable pocket called the "sugarbowl". In perfect condition and far more bright and glittery in person.
