Petzite with Gold etc.
stock #8.1-260
#5 Level, Rex Mine, Gold Hill District, Boulder County
Colorado, United States
3.8 x 2.6 x 1.3 CM (small miniature/ large thumbnail (toenail))
price: $300


A very rich small specimen of this rare Gold Telluride from Boulder County, Colorado. The Petzite here is in metallic masses and almost half of the specimen is Petzite. The remaining matrix is quite rich in tiny, bright specks of gold seen well under magnification. Two additional areas of golden massive mineral appears to be Coloradoite (not x-rayed but this was a common association and the visual match is very good). I can not find any clearly crystalized Hessite on this piece though a few spots at 20X look like crude crystal faces. A good sized (13.8 grams) and quite rich mass of this rare Gold Telluride from a classic USA locality.
Calcite
stock #13.1-177
York Stone Quarry, York, York County
Pennsylvania, United States
5.4 x 4.2 x 2.5 CM (small cabinet/ large miniature)
price: $120


Transparent Calcite crystals with highly lustrous faces and in choice condition. From the York Quarry which is a famed locality for fine Calcites. This piece has especially good color and the display side is perfect, undamaged, there is a contact and bruise only on the backside not seen in any normal angle. The striations of the faces are very distinct. A very slight melted look is noted on some corners as was common at this locality.
Fluorite - etched plate
stock #15.1-582
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
7.2 x 6.5 x 2.4 CM (cabinet)
price: $290


Orange-yellow color Fluorite crystals with a few purple edges from Southern Illinois. The crystals have some amount of etching on some faces while others are smooth and glassy. Minimal rough spots, though not perfect the overall condition and color are choice. One of the more rare colors for an Illinois Fluorite, this piece dates to the 1960's.
Barite - classic USA
stock #15.1-850
Stoneham, Weld County
Colorado, United States
4.6 x 3.8 x 2.3 CM (miniature)
price: $110


A small but esthetic Stoneham Barite in fine condition. A modern US classic from these great finds that produced many choice specimens. Due to the quantity and quality of the discovery nice specimens are still quite affordable. A good value, complete on all sides, no damage.
Amethyst scepter
stock #A7-468-(1018)
Deer Hill locality, DeerHill, Stow, Oxford County
Maine, United States
3 x 1.5 x 12 CM (thumbnail)
price: $75


Thumbnail sceptered Amethyst with zoning and a deep purple cap. Ex Larry White thumbnail collection, a nice example from this classic Oxford County Maine (USA) locality that is better known for very large crystals, good thumbnails are quite rare. The condition is excellent.
Azurite - crystal rosette form
stock #20.1-309-(LW486)
Hanover #2 Mine, Grant County
New Mexico, United States
2.6 x 1.9 x 1.5 CM (thumbnail)
price: $550


A perfect and brilliant blue Azurite rosette or flower from the Hanover mine in New Mexiso. 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 competion 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. .
Silver and Copper (halfbreed)
stock #14.1-269
Caledonia Mine, Mass City, Ontonagon County
Michigan, United States
2.2 x 1.7 x 1.2 CM (thumbnail)
price: $110


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
stock #20.1-304-(LW631)
Ray Mine, Ray District, Dripping Springs Mountain, Pinal county
Arizona, United States
2.8 x .9 x .5 CM (thumbnail)
price: $90


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.
