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.
Transparent colorless crystals of Anothite are nestled in a shallow vug. An old specimen (three old European labels accompany this) from Monte Somma the type locality for the specie. The crystals are up to 5 mm though most are smaller. In excellent condition with no visible damage, this is great under magnification as the sharp, glassy crystals have very bright luster.
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.
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.
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.
Jeffrey Mine, Asbestos

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.
