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 noticable 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.
Celestite on Calcite
Cave-in-Rock, Hardin County
3.9 x 2.6 x 2.3 CM (small miniature)
new year 2021
A small but very esthetic specimen from the prolific Fluorospar region of Southern Illinois. Ex. Larry White collection, the Celestite (or Celestine for many) is a terminated flat prism set on light yellow Calcites. Unusual in its composition, this piece has considerable display impact despite the small size and is in excellent condition. This zone produced many thousands of great Fluorite specimens but very few good Celestites were saved.
Bright lustrous Linarite crystals on a contrasting matrix. From the Grand Reef Mine, this specimen has numerous species on board. The Gearksutite is is present as porcelaneous green masses. Linarites are very sharp and transparent with typical vivid color. A modern USA classic locale, this is a mid sixties vintage specimen.
Faden Quartz (gemmy yellow)
Barranc del Cargoi, Arestul Llavarsi, Pallars Sobira, Lerida
5.2 x 2.4 x .4 CM (small cabinet/ large miniature)
new year 2021
A perfect, gem-clear yellow Quartz crystal that has tabular form and a distinct faden line inside. Excellent, undamaged and with textbook form. Certainly a very choice faden from anyplace, this important small locality has alpine type veins and distinctive tabular forms. The color is a nice yellow to light orange at some angles, this seems to qualify as a Citrine. A clean floater, this is doubly terminated and the nicest specimen I have seen from this interesting locality.
A historic specimen of Lazulite crystals well-exposed on a small matrix. The second photo includes the original label from Charles U. Sheppard Jr which indicates this was from a brief period of mining at this site specifically for mineral specimens. Sheppard's father was one of the great early USA mineralogists, he studied this deposit and published in 1856. His son (Jr.) later was a part owner and mined this locality for the international specimen trade and exchange with institutions. Sheppard Jr died in 1915, though the specimen is likely over 150 years old. This Lazulite thumbnail has several crude crystals on it the largest and best is 1.6 CM tall and covers much of the front or display side. This locality produced a very few exceptional world class Lazulite; this one is not that exceptional but is certainly above average and has the rare original label that dates back to one of the first specimen mining operations in the USA. An affordable and nice classic.
