Quartz - gem
Lasselville, Town of Ephratah, Fulton County
1.8 x 1.4 x 1.2 CM (thumbnail)
A perfect thumbnail of gem-clear Quartz with a form that looks a lot like a Herkimer Diamond but is from the less well-known locality of Lasselville in Fulton County, NY. No damage, with fine esthetics, collected in 1972 by Larry White. This had been in his thumbnail collection for more than 40 years.
An etched, gemmy elongated crystal of Marialite (an end member of the Scapolite family). This is in fine condition overall, the termination is complete and this is almost colorless but has a hint of yellow hue under some light sources. Well-etched striations with a distinctive silky luster, this thumbnail was in the Larry White collection, obtained from Luiz Menezes in 1995.
Silver and Copper (halfbreed)
Caledonia Mine, Mass City, Ontonagon County
2.2 x 1.7 x 1.2 CM (thumbnail)
A US classic a choice Halfbreed of Silver and Copper that shows perfectly the two metallic colors with very bright luster. Looks fine on all sides, the Halfbreed masses from this region are unlike anything from other places. The copper mined in the Upper Pennisula of Michigan tended to have some small percentage of Silver mixed in. This was especially desirable in the early manufacturing of electrical wires.
Beryl var. Emerald
Muzo Mine, Muzo, Municipio de Muzo
1.2 x 1.1 x .8 CM (thumbnail)
A single Emerald from the famed Muzo Mine, this is a gemmy hexagonal crystal with good green color. The crystal has some breakage mostly on the back and lower areas, some scuffs as well as a few inclusions. That said, it is a terminated crystal and a genuine transparent Emerald. Perfection in Emeralds is crazy rare and insanely expensive. This is a cute though not perfect thumbnail at 9.4 carats and is priced below the usual rate for this grade of rough.
A perfect small thumbnail of native Copper that has faithfully replaced a hexagonal Aragonite crystal. The Aragonite form is textbook perfect and the patina is a choice red copper hue. No damage, complete all around this is both sharper and with better color than usually seen. These pseudomorphs were found more than 30 years ago and not since. Ex Larry White collection.
2.3 x 2.1 x 1.8 CM (thumbnail)
Tsumeb Azurite in blocky crystals showing bright luster and color. A choice thumbnail from the collection of Larry White, this is in excellent condition and the crystals are well contrasted by the light matrix.
Fluorite on Sphalerite
Elmwood Mine, Carthage
5.3 x 4.3 x 3 CM (cabinet)
A sharp single Fluorite perched on a complexly crystallized Sphalerite matrix. The Fluorite is transparent, and has geometrically etched, stepped structures on its faces. The front or display side is in perfect condition, a tiny cleave is noted on the back side that is almost invisible by naked eye. The Fluorite is like a small jewel, the color is purple blue. There are still some good values to be found in Elmwood Fluorites.
San Juan de Rayas Mine - Level 407
2.2 x 1.3 x .6 CM (thumbnail)
Branching crystals of Acanthite forming a tree-like thumbnail with very bright metallic luster. Complete all around, undamaged and pretty. A very good yet still affordable Silver specie from the famed Guanajuato deposit. This area has been continuously mined for Silver since the discovery in 1585, and this was the world's largest producer for many years. Amazingly there are still a few operating mines and Silver minerals are still found though far less than before.
