Diopside - doubly terminated gem crystal
stock #21.1-163
Merelani Hills, Lelatama Mountains, Simanjiro District
Manyara Region, Tanzania
3.2 x 1.7 x .9 CM (small miniature/ large thumbnail (toenail))
price: $680
New Year 22

A perfect, complete doubly terminated green Diopside that is fully transparent gem. Of the dozens of these Diopside seen on Mindat none are doubly terminated, this is a very rare example. Some complex geometric internal structures are seen with a close exam as are a few internal Graphite crystals. No damage, and very glassy luster. From Merelani, famed for Tanzanite crystals, these gem Diopsides are much less common on the market, and doubly terminated crystals are very rare in any quality.

Bournonite with Siderite on Quartz - classic German
stock #20.1-896-(ZS-BRN4125)
Pfaffenberg Mine, Neudorf, Harzgerode, Harz Mts.
Saxony- Anhalt, Germany
2.6 x 2.1 x 2.2 CM (thumbnail)
price: $480
New Year 22

A superb classic thumbnail specimen from the famed Neudorf area, best known for world-class Galenas and rarely some great Bournonites. In flawless undamaged condition. These Bournonites are bright, lustrous metallic crystals on a matrix of sparkling white Quartz that is also the host for fine Siderite crystals. This can be displayed in several orientations, it is almost impossible to find a choice thumbnail like this from Neudorff today. A few earlier labels are included, this sort of specimen is certainly very old.

Amethyst - sceptered crystal
stock #21.1-219
Piedra Parada, Las Vigas
Veracruz, Mexico
4.7 x 3.2 x 2.2 CM (miniature)
price: $160
New Year 22

A small, well-composed specimen of Amethyst perched on a contrasting matrix with a druse of greenish Epidote. From the prolific finds at Piedra Parada, the Amethyst is distinctly sceptered and in perfect condition. These Amethyst when they are perfect like this are one of the best current values in minerals. We hope the locality can continue to produce for a long while.

Gordonite (rare Phosphate) on Variscite, type locality
stock #20.1-139
Little Green Monster Mine, Clay Canyon
Utah, United States
3.4 x 2.7 x 1.9 CM (small miniature/ large thumbnail (toenail))
price: $450
New Year 22

A rind of tiny, glassy Gordonite crystals on a Variscite nodule that has a tiny bit of Crandallite as well. From the type locality in Utah. This is the type locality for this specie found during the famed excavation project by Ed Over and Arthur Montgomery in the 1930's. The individual micro crystals are up to 1.5 MM in size, which is fairly large for the specie. These are both isolated, free standing and in radiating sprays. Remarkably the main cluster of crystals extends across 1.5 CM which makes this specimen an incredibly rich example, very fine for this rare specie.

Senarmontite - type locality
stock #20.FC-079A-(9190)
Djebel Hammimat Mine, Ain Babouche District
Oum el Bouaghi Province, Algeria
1.8 x 1.6 x 1.5 CM largest (thumbnail)
price: $360
New Year 22

A pair of sharp and very large Senarmontite crystals with classic form from the type locality. This rare Antimony Oxide was found sporadically between 1850 to 1950 at this locality by the French Geological exploration group BRGM. These remain as the best and largest crystals of this specie. These crystals are far larger than average at this locale and are well-defined. Worldwide Senarmontite is found in just a few other Antimony deposits, usually as micro-sized octahedra not often much larger than 1-2MM. Very fine for the specie and not often available, Ex Paul Sainfeld and Tunisian Geological Service collections.

Epidote - Northeastern USA classic
stock #17.1-822
VAG Mine, Lowell & Eden
Vermont, United States
5.1 x 1 x .9 CM (small cabinet/ large miniature)
price: $600
New Year 22

A single sharp and glassy Epidote crystal with perfect termination from the famed VAG Mine, (aka Belvidere Mt./ "Eden Mills" Vermont), find made over 35 years ago. This zone produced several very fine crystals including the largest complete Epidotes ever found in the USA (and perhaps the world). This specimen is much smaller than the giants but has no repairs (the big ones were broken). Almost never available except in older collections, this is in perfect condition, partly transparent with well-defined striations.

Pyromorphite on Coronadite - classic locale
stock #19.1-817
MMM Mine, Broken Hill, Yancowinna County
New South Wales, Australia
11.4 x 7.5 x 4.1 CM (cabinet)
price: $800
New Year 22

A large and rich cabinet sized Pyromorphite on Coronadite from Broken Hill. A classic locality and a classic association from this iconic mine. The matrix is very three dimensional, a botryoidal black background for hundreds of very lustrous olive green Pyromorphites. Under the Coronadite is massive Galena and a little Cerussite that is not seen from the display side but adds a heft to the specimen. In exceptional condition, very hard to appreciate in photos but an excellent classic in person.

SOLD Calcite - classic USA
stock #SOLD 17.1-592
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
8 x 6.8 x 4.7 CM (cabinet)
price: $0


Sharp and very esthetic clusters of tapered "flame" habit Calcite from the famed Minerva #1 Mine. These Calcite have elongated prisms that are almost needle-like at the terminations which are very slender and delicate. A classic of the southern Illinois Fluorite district, these are not often seen for sale. An important and unique style this is an excellent addition to a good Calcite or southern Illinois collection. The Calcites are all frosted with a white coating but below that they are a bright yellow-orange color. Some tips on the left side back are cleaved but nearly all the others are perfect. From logical display angles there is no visible damage and the condition is excellent for one of these delicate Calcites.
