A rare locality specimen of bementite, named after noted collector Clarence Bement. I had never seen material from Nevada before. The label notes that it is here "all the brown material" in which case, this would be quite rich!

JWHITE-23 - Linarite - $ 450
Grand Reef Mine, Laurel Canyon, Graham County, Arizona, USA

A rather large, showy linarite crystal, with electric blue color, from the best find in Arizona . Specimens from this deposit are very rare now, and this is an excellent thumbnail example

Brilliant, silvery-metallic microcrystals of dyscrasite atop a ridge of native arsenic ore. Beautiful under a scope. He purchased this from Walt Lidstrom in 1974 and note the added comment.

Two hair-like clusters of acicular uranophane crystals, perched nicelyon a matrix plate . This is classic, now rare, material from this old uranium mine in Bancroft area.

Vanoxite in Sandstone with Carnotite from Uravan, Montrose Co., Colorado, USA [db_pics/new09/sea16b.jpg]

Vanoxite is a vanadium oxide with water that is , I think, the vanadium equivalent of rust or of rustlike mineral species we see commonly with iron and manganese. However, it seems fairly uncommon. Apparently because it does not crystallize, its IMA status is listed as Questionable/Doubtful as a species although that is a supposition. In any case, the material is present here as dark material in the matrix of carnotite (for which this is an excellent reference specimen)

JWHITE-11 - Collinsite with Asphaltum - $ 100
Francois Lake, Omenica Mining Division, British Columbia, Canada

Collinsite from this locality, according to MINDAT, is said to have its orgiins in large deposits of guano, or bat poop. This is a classic find for the study of such origins, apparently. The collinsite here is in light brown, fibrous aggregates associated with fluorapatite on andesine. Also in association is "wurtzilite", now known as asphaltum, a natural hydrocarbon mineral more commonly referred to perhaps as "tarry goo."

JWHITE-09 - Skutterudite on native Bismuth - $ 400

A solid mass of very heavy, metallic ore is host for sharp crystals of smaltite, the cobalt-rich variety of skutterudite. Classic old material! This is a good display piece with crystals to 4mm including a sharp cube, atop. I have chosen not to clean this piece of its acucmulated patina, though it is of course easy to make it cleaner and bright-looking with chemicals. Note the attractive wavy growths of native bismuth, on which the crystals sit.

JWHITE-06 - Betafite - $ 450
Silver Crater Mine, near Bancroft, Ontario

A rather large, 3.5-cm-tall crystal from this classic locality known for the material. But specimens like this, and relatively (I use the word carefully here) attractive as a display piece, are uncommon. Old Wards Science label accompanies

JWHITE-05 - Calcite - $ 200

A briliantly lustrous, sharp single crystal of calcite with origins, according to its old label, from the tunnel project here in St. Gotthard pass. Rare locality specimen, and a good calcite crystal as well!

A VERY VERY rich specimen with both sides smothered in microcrystalline, deep blue papagoite. This is from the TYPE LOCALITY circa 1960s. (TYPE LOCALITY). It has an old Scott Williams company label with it. Not only is this significant for the rarity and locale, but it is a relatively large, and pretty, plate

Sharp, very rare , lorandite crystals to 3 mm on matrix�and overall a rich concentration of them, too! This is a great locality piece , and example of this rare thallium-containing species. Very few thallium mineral species, of the few that do exist, form macrocrystals.
