Copper - branching crystals
Santa Rita, Grant County
3.3 x 2.6 x 1.2 CM (small miniature/ large thumbnail (toenail))
A complex branching Copper specimen composed of many small crystals in stacked or aligned arrangements. Good patina, the color ranges from a dark that is almost black to a red copper hue. A multitude of tiny crystals in many divergent habits are best appreciated under magnification.
Schorl with Cleavelandite
Urucum Mine, Galileia
3.4 x 2.6 x 1.7 CM (thumbnail)
A "candelabra" style specimen of slender Tourmalines in a pretty arrangement offset by well-crystallized Cleavelandite. This will fit in a thumbnail box (barely) and has very nice contrast. Originally labeled as an Elbaite, but on close study it is a Schorl. Ex Larry White collection he obtained it from the Brauns in 1975. I do not see many attractive Schorl of this sort and never in thumbnail size. While not a rare specie it is surprisingly rare to see in thumbnail collections.
Classic form Chrysoberyl from the Ragged Ass Jack Mountain find in Maine, USA. This is a complete crystal, fully transparent and with nice color. The twinning can be clearly seen by the distinct striations. This thumbnail is from the Larry White collection which he obtained almost 50 years ago from Phil Scalisi who in turn got this from the Grace Dearborn collection. For this locality the quality and condition is super, a few larger crystals are known but those are far less sharp, gemmy and complete. A rare and choice USA Thumbnail and a fine Oxford County, Maine piece as well.
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.
Cuprite with Native Silver
Rubtsovsky Mine, Rubtsovshy District
4.6 x 4.6 x 4 CM (miniature)
Just over a decade ago the incredible discovery of fantastic large Cuprites from Rubstovsky (Russia) was huge news in the mineral world. This is an especially choice example of a fine undamaged Cuprite with the addition of having Native Silver on some areas. Even without the Silver this is a super Cuprite, it has excellent form and luster, is in fine condition and with good lighting the inner red colors are seen on some edges and faces. This piece was found in the early discoveries, it is of a style and quality that is no longer coming out (the find may have been exhausted but there are still some coming from dealers storage). The bright luster makes this hard to show well in photos, it is far better in person and very fine for the discovery.
