A superb and very esthetic old "Eisenkiesel" that looks like a volcano showing bright red Quartz in the crater. The Hematite is a big heavy hemisphere on the outside, but the inside display side has the open oval void that is filled with sparkling blood red crystals mimicking lava. A small amount of the red Quartz seems to be flowing down one of the volcano sides. Looks great from most any angle, the color is more vivid than others I have seen from the UK and the form is exceptional, a top example from anyplace. In great condition, there is no damage. Classic.
Two crystals of Mn rich Willemite (Troostite) in Calcite collected by Wallace Gould Levison in 1889. While the Troostite variety of Willemite is only known from the Franklin and Sterling mines, this specimen was actually collected in Jersey City, New Jersey at the Zinc Works there. It was found in a load of Zinc ore transported from Franklin to the smelter there, so this is unique, being probably the only Troostite that was not collected from Franklin. The Willemite crystals are a brick red color, well-formed though with typical slightly crude edges up to 3.1 CM. We will include a photocopy of the handwritten ledger from the Levison collection. Levison was a prolific 19th century collector located in Brooklyn who became very interested in the fluorescent minerals of Franklin. He invented and patented a specimen viewing box for shortwave UV light in 1909. A nice specimen with a great provenance.
Cerussite - bipyramidal twins
Grand Reef Mine, Graham County
3.9 x 2.7 x 1.6 CM (small miniature/ large thumbnail (toenail))
new year 2021
Several hexagonal crystals of glassy Cerussite on matrix which look a lot like Cumberland habit Quartz. These bi-pyramidal twinned prisms sit on a complex matrix of Quartz some of which is colored pale green by inclusions. From the remarkable Grand Reef Mine that is famed for other lead secondaries; this is a nice small miniature in excellent condition.
A very unusual looking specimen of Sphalerite with some bright red and darker crystals perched on a thin shard of Chert matrix. Ex Wallace Gould Levison collection, he obtained this piece in 1909 from the "northeast corner of the Quaparo Indian Territory, A zinc mine there" his notes give the source as George R. Osborn who was located in Kansas City, MO. This area we know today as the Quapaw territory of Ottawa County, Oklahoma. Mining had begun on the Indian territories in 1908 so this is a very early specimen. The area became a very important Lead Zinc supplier though the Indians were not compensated as agreed. Mining ended in 1950 but for a while this was the world's largest Pb Zn source. The specimen has well-formed crystals with the largest 2.3 CM. Smaller crystals are translucent to transparent and this is quite esthetic in person. We include a photocopy of Levison's original collection ledger page with this specimen. A very nice quality Tri-state classic specimen with unusual early provenance from an important US collection.
A USA classic from the Walworth Quarry. Perfect, glass-clear transparent Fluorite sits exposed on Dolomite matrix. The cube is 2.3 CM diameter and several flat needle like crystals of Anhydrite are clearly seen inside. The Fluorite has the most desired blue color and the matrix is seen perfectly through the crystal. This specimen is sawn on the base which is commonly done to collect these without damage in the very hard matrix. The saw marks are not really noticeable in most display positions. We can arrange for a prep lab to use pneumatic tools to roughen the sawn surface if desired though this is certainly not needed, and incurs a cost. Walworth Fluorites are highly desired in fine condition like this, some many have at least some damage. These are a modern classic, the quarry is still operating and twice each year collecting is allowed for one day. Some years little or nothing good is found, such good undamaged specimens are very rare and highly prized.
Santa Rosa Mine, Itambacuri
2.6 x 1.3 x 1.3 CM (thumbnail)
new year 2021
A zoned green flat top terminated Elbaite crystal from old finds at Santa Rosa. The crystal has good glassy luster, moderate transparency and only one small .5 mm chip. Weighs 7.4 Grams, this is priced below typical market rates. Pretty, affordable tourmaline that glows well when backlit.
Elegant branching tendrils of Copper in a treelike tangle from the White Pine Mine. Close exam shows these to be delicate chains of elongated Copper crystals. This locale is a classic locality for fine Copper and Silver specimens, this one is especially esthetic, and has a nice patina. Ex Larry White collection, Larry had excellent taste for native metals and esthetic compositions. The White Pine mine was famed for its spectacular branching coppers. Specimens like this piece are very very different from most other locales in the Upper Peninsula, and for that matter anyplace else.
Galena - spinel twinned
Krushev Dol Mine, Madan, Rhodope Mts.
9.5 x 4.8 x 3,7 CM (cabinet)
new year 2021
A killer Galena with very well defined geometric structures which are the flattened Spinel twinned crystals. Remarkably there is no damage and the luster is super metallic. From a remarkable find in 2010, this comes from a single pocket that had especially well developed sharp edged Galenas that were sprinkled with some Quartz crystals. The look is similar to some Spinel twinned Galenas from Dalngorsk but also distinctly unique. These are more tabular crystals with thin sharply crystalized edges. These have been described by some as "star wars" Galenas. they do look like spacecraft structures in person. We have been keenly interested in the Galenas from Bulgaria for years, this particular find and the few specimens of this caliber are to my taste the best.
