Grossular from Jeffrey Mine that is transparent, has fine orange color and has several slender crystals of Diopside seen inside the Garnet. Aside from some very small contacts and rough edges this is in fine condition. The luster is glass-like and this crystal has very few striations on the large faces which makes it easy to see through these windows into the crystal. Ex Larry White thumbnail collection, he obtained this in the early 80's when the mine was still active and great things were being found.
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.
Copper - spinel twin
Ray Mine, Ray District, Dripping Springs Mountain, Pinal county
2.8 x .9 x .5 CM (thumbnail)
Slender, elongated spinel twins of Copper from this classic USA locality. This looks fine from all angles; it comes from the Larry White thumbnail collection. A good example for the location and a choice thumbnail.
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.
