Fluorite - classic British yellow
stock #19.1-405
Hilton Mine, Scordale, Hilton Escarpment District, Murton, Eden
Cumberland, Cumbria, England
5.7 x 4 x 3.2 CM (cabinet)
price: $280
new year 2021

A nice cluster of gemmy and sharp Fluorite cubes from the famed Hilton Mine, collected in 1974 by Les Hitchings. The crystals are quite clear, transparent and undamaged. The largest cubes are over 1.2 CM across and have a vivid fluorescence as is typical of much Fluorite from this region. The Hilton Mine was of great importance to mineral collectors as it was the source for lemon-yellow Fluorites which were quite distinct and different from most other British locales. A very nice yet more affordable specimen of this classic material.

Tanzanite (Gem Blue Zoisite)
stock #19.1-849
Merelani Hills, Lelatama Mountains, Simanjiro District
Manyara Region, Tanzania
1.8 x .9 x .7 CM (thumbnail)
price: $330
new year 2021

A brilliant blue thumbnail gem crystal of Tanzanite. In excellent condition with glassy luster and fine transparency, this is an affordable specimen of this often very expensive mineral. Good Tanzanite like this has a striking color shift across the "C" axis when rotated it shows a purple color shift. Some color zoning is seen in the crystal but it is overall a choice royal blue. 5.17 Carats

SOLD Lepidolite with Muscovite core
stock #SOLD 16.1-751
Aracuai, Jequitinhonha Valley
Minas Gerais, Brazil
9 x 5.7 x .4 CM (cabinet)
price: $0
new year 2021

An oddity, this is an attractive well-formed Mica crystal with fine zoning and a sharp transparent window in the core. The outer zone of Lepidolite is a rose purple and shows thin color bands when backlit. This piece is from a small lot that arrived in 2017 and I have not seen anything like this since.

Hiddenite (Spodumene) - vintage USA Classic
stock #15.1-699
Stony Point, Alexander County
North Carolina, United States
2 x 1 x .6 CM (thumbnail)
price: $750
new year 2021

A fine single crystal of Hiddenite from the area of the original discovery in Alexander County, North Carolina. While green Spodumenes have been found in other regions, true "Hiddenite" only comes from this locale and these do not fade their colors like green Spodumene from elsewhere. It had been surmised that a Chromium content adds the color as it does to the Emeralds that are found in the same area. However testing for both Chrome and Vanadium has not confirmed this. This specimen is from the Dr. Warren Johansson collection which he obtained in 1934. The crystal is fully natural (no irradiation), doubly terminated, gemmy, undamaged with good color and complex etching. These were never common and are now quite rare.

Calcite
stock #AX-22-173
Pony Express Mine, Gold Hill District, Ouray County
Colorado, United States
5 x 3.8 x 3 CM (miniature)
price: $60
new year 2021

Scalenohedral Calcite crystals from this Ouray county mine are quite different from others in this famed region. This is a sharp, distinct example of stacked and bundled scalenohedral crystals that are partly coated and included by Goethite. This is an older specimen from the William Hladysz collection, not often seen for sale.

Pyrrhotite with Quartz and Sphalerite
stock #16.1-384-(CN5015)
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Russia
4.9 x 4.3 x 3.4 CM (miniature)
price: $320
new year 2021

Nicely composed miniature from the great Dalnegorsk deposits, ex Charles M. Noll collection. The Pyrrhotite crystal is perfectly perched, the wide terminal face is a brassy, slightly subdued hue and the edges are a brilliant golden with mirror bright luster. In perfect condition with no damage seen even with magnification. There have been many good Pyrrhotites found at Dalnegorsk yet it can be hard to find a miniature with standout quality and esthetics. Better in person.

SOLD Rosasite inside Gypsum on Dolomite
stock #SOLD 20.1-829
Bou Beker, Touissit -Bou Beker mining district, Jerada Province
Oriental Region, Morocco
7.8 x 5.7 x 2.2 CM (cabinet)
price: $0
new year 2021

From a very unusual find a few years ago at the Bou Beker Mine in the Touissit complex in Morocco. A Matrix of pink Dolomite crystals is the background for colorless gypsum in two generations with both prismatic clear crystals and colorless balls. The spherical globs are colored by inclusions of blue-green Rosasite and a few small spots are a darker green from Malachite crystals best seen under magnification. In perfect, undamaged condition, this is a much more dense and colorful example than usual from the find. Previously in my personal collection, these were plentiful at one time and very affordable, they are still a very good value. Early on some dealers had labeled these as Devilline inclusions, but that was incorrect. Choice and colorful, a lustrous and unusual specimen of a sort that is just not found any place else and now rarely available in any quality.

Dioptase with minor Calcite
stock #6.2-923
Tantara Mine, Shinkolobwe, Kambove District
Haut- Katanga, Democratic Republic of Congo (Zaire)
6.2 x 5 x 4.3 CM (cabinet)
price: $800
new year 2021

Brilliant gemmy Dioptase crystals with intense emerald green color cover the face of the matrix. From the Haut Katanga area of the D.R.Congo, this fine older specimen has the top luster and color more like that sought after in Tsumeb specimens. More recent Dioptase finds tended to be more matte luster or had stepped faces, with much less flash. This is great for the locality and a classy Dioptase from any place. The crystals are very well-defined and reach 1.3 CM. In person this is a strong display specimen with color that is impossible to appreciate on a computer screen. Overall in very good condition, there is some chipping at the outer edges but most of the important crystals are perfect and the display impact is not diminished.
