SOLD Fluorite - gemmy zoned on Calcite
stock #SOLD 21.1-166
Yindu Mine, Hexigten Banner, Chifeng City
Inner Mongolia Region, China
3.8 x 2.3 x 1.8 CM (thumbnail)
price: $0
New Year 22

A killer thumbnail from the unbelievable finds at the Yindu Mine (China). We have been very impressed with the this locality since it began producing fine specimens, however there has been almost nothing in thumbnail size of any quality. This is the first really good piece we have seen in this size. Well-composed and balanced with a perfect gem clear zoned cube prominently perched on matrix. Excellent luster and better in person, the vivid purple core is set in a clear blue box. Yindu has made some great impressions for a few of the better specimens found over the past two years. The great ones are just a tiny percentage but they are amazing and already command some very high prices. This is a fine piece of competition grade in a small size that is not insanely expensive.

Spinel - dark blue to purple crystals
stock #21.1-378
Pein Pyit, Mogok, Pyin-Oo-Lwin District
Mandalay Division, Myanmar (Burma)
4.8 x 4.3 x 3.3 CM (miniature)
price: $340
New Year 22

Glassy octahedral crystals of Spinel from the famed gem regions of Mogok in Myanmar. At first glance this looks almost black but under good light the color is a blue to purple-red color in zones and the crystals are transparent to translucent. In person the luster is brilliant and the condition is also very fine. These crystals have the typical rounded or melted look in some places but are very sharp on most edges. Much of the Spinel from Mogok is vividly fluorescent red, this is not, but under long wave is an unusual pale green. 60.45 grams overall there are a few areas of gem clarity but most is included. A nice and very unusual Mogok Spinel.

Rashleighite (ferroan Turquoise aka Henwoodite) Type area
stock #AX-10-815
St. Austell
Cornwall, England
9.8 x 5.8 x 4.8 CM (cabinet)
price: $600
New Year 22

A large and rich specimen of this uncommon Turquoise variety from the St. Austell district where this was originally described from several mines. The Rashleighite is a botryoidal green covering much of the matrix. This is set off nicely by sparkling micro crystals of what seems to be very transparent Siderite. A sizable and colorful old Cornish specimen.

SOLD Datolite with Pectolite - historic with G. Kunz signature
stock #SOLD AX-27-224
Bergen Tunnel (Erie RR. "old tunnel" Jersey City, Hudson County
New Jersey, United States
8.8 x 4.9 x 2.9 CM (cabinet)
price: $0
Late Summer 2021

A fine Datolite specimen from a long gone Historic locality, the Bergen Hill tunnel. One of the old labels with this is handwritten and SIGNED by George Kunz, the famed mineralogist Kunz sold many minerals and built three major collections during his career but signed Kunz labels are very rare. This specimen is from the "old tunnel" in Bergen Hill, built in 1857-60. This would have been collected during that construction. A later tunnel in 1881 was dug nearby, both were important localities during the construction but not since. Specimens are now only seen in very old collections, yet this was a significant early US source of Traprock minerals. The Datolites are tiny, very lustrous sparkling crystals some of which seem to have coated earlier Pectolites. There are still numerous Pectolite crystals present especially on the backside. The Datolite seems to be formed in two different generations, most of the crystals are colorless but there is a very faint hint of color in person. Documented specimens from the "Old Tunnel" are very rare on the market.

Fluorite with Siderite - vintage German specimen
stock #21.1-200
Rottleberode, Sudharz, Mansfeld-Sudharz
Saxony- Anhalt, Germany
6.2 x 5 x 3.8 CM (cabinet)
price: $300
Late Summer 2021

Blue-green Fluorite crystals reaching 3.3 CM with several distinct Siderite crystals on and between the Fluorites. A nice old German piece with labels from A. Kranz and another earlier collection, this is in very good condition overall. This locality was worked for a very long time and finally closed about thirty years ago, though we believe this specimen is at least 100 years old. The Siderites are in well-formed lath type crystals and show curved faces much like Dolomites. A classic piece from the southern Harz Mountains, we rarely see specimens from this locale here in the USA, this one is well better than average.

Chrysocolla fingers with Quartz coatings
stock #13.1-176
Ray Mine, Ray District, Dripping Springs Mountain, Pinal county
Arizona, United States
3.6 x 2.1 x 1.2 CM (miniature)
price: $550
Late Summer 2021

A cluster of Chrysocolla "fingers" with perfect, undamaged tips from the Ray Mine,(Arizona, USA). Sometimes called stalactites, that is not technically correct as there is no central canal or hole in the middle. This has excellent turquoise color and a pearly luster. Close exam shows the thin layer of Quartz that is like a skin over the Chrysocolla. It is very hard to find such perfect examples with all the fingers intact. A colorful and classic USA copper specie.

Spharosiderite (Siderite)
stock #17.1-267
Estacada Pyrite locality, Clackamas County
Oregon, United States
7.4 x 5.3 x 4.1 CM (cabinet)
price: $280
Late Summer 2021

Sphaerosiderite is a fairly rare form of Siderite usually found in Basaltic flows, and can form in a diverse array of habits. On this piece the red color balls are scattered in an open cavity. A very esthetic specimen in fine condition having great contrast with the cavity lining. Under strong lighting the orange-red Siderites are rather sparkling. These are a lower temperature type of structure that are essentially a microcrystalline rosette form that has a very distinctive habit. Worldwide these have been found as very smooth spheres often with a metallic or smooth luster. The finds in Clackamas County are more often this type of red balls with a textured surface. This is a well-defined and attractive example from this region. Ex Hitchings collection.

Pyromorphite - USA classic
stock #0847-JM-2124
Little Giant Mine, Mullan, Coeur d' Arlene District, Shoshone County
Idaho, United States
7.6 x 5.6 x 3.1 CM (cabinet)
price: $690
Late Summer 2021

Well-crystallized Pyromorphite crystals cover a matrix plate from the Little Giant Mine (Idaho, USA). This region has a long mining history and is well-known as the home of the Bunker Hill Mine, one of the world's great Pyro locales. Less famed but still quite important is the Little Giant, and this is an excellent example for this locality. A choice addition to a serious suite of Pyromorphite the quality is much better than just a locality specimen. Ex John Marshall Collection; John was a passionate collector of Pyros and his taste was excellent. John purchased this specimen in 1974 from the Paul Zimmerman collection. His collection card states "One of the best pieces I have ever seen from the locality". It is outstanding for this mine.
