4.1 x 2.8 x 2.3 CM (miniature)
Sagenite type Rutile inside Quartz from the Binn Valley. Classic alpine specimen that has been recrystallized on the bottom and back.

Azurite - crystal rosette form
Hanover #2 Mine, Grant County
2.6 x 1.9 x 1.5 CM (thumbnail)
A perfect and brilliant blue Azurite rosette or flower from the Hanover Mine in New Mexico.Complete all around, with vibrant color, luster and no damage. Ex Larry White collection, this is essentially a single crystal with several smaller crystals that are aligned to create the rose form. There is no point of attachment so this a complete floater, it ranks as a competition grade specimen and I have not seen a better thumbnail from here. These are now very uncommon to find for sale except as old collections are broken up. A small collection number has been painted on a corner of the "back" of the piece, we can remove it if requested. Far better in person the electric color is hard to capture or see on a computer screen.
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.
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.

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.
