Sphalerite - gem crystal on Quartz
stock #24.1-158
Empire State #4 Mine, 3900 foot level, Balmat, St. Lawrence County
New York, United States
3.5 x 2.7x 2.2 CM (thumbnail)
price: $480


A killer thumbnail with a flawless gem clear Sphalerite twin perched on contrasting Quartz crystals. From the incredible new find of these Sphalerites at Balmat, New York in the #4 Mine at 3900 feet down. There were quite a number of nice thumbnails in the find, but just a few of this quality and esthetics, most were very quickly snapped up. Certainly destined to be classics, the better specimens from this locality are modern mineral treasures. Bright glassy luster, yellow-orange color and perfect clarity.

Green Anglesite - classic Cuprian Anglesite
stock #23.1-323
Montevecchio Mines, Medio Camcampidano Province
Sardinia, Italy
6.8 x 5.6 x 3.3 CM (cabinet)
price: $340


A classic old Sardinian specimen and highly sought after bright green Anglesites on typical matrix. There are several green crystals of Anglesite on this specimen, largest 1.7 CM, but sadly most have noticeable damage, only some small ones in vugs are in good shape. Despite the damage the color is good, it is very hard to find any such specimens. The Anglesites are fluorescent yellow and the matrix exterior is a botryoidal Gossan with a core of altered Galena hosting the Anglesites. Montevechio is an ancient mine worked even before the middle ages. Green Anglesites were found long ago and are something of a holy grail for many. The damage here is heart breaking but makes this a very affordable example of this rare Lead secondary. In better condition could easily be a mid 4 figure piece.

Sand Calcite
stock #22.1-563
Bellecroix Plateau, Fontainbleau, Seine-et-Marne
Ile-de-France, France
5.8 x 4.3 x 2.7 CM (cabinet)
price: $650


A classic of mineralogy, the sand Calcites from the French discoveries around Fontainbleau have been prized over centuries. This is an especially sharp and perfect example of the complex morphology that has made these famous in the mineral world. No damages or contacts at all, this is complete on all sides. Even though Calcite is a very common mineral, this style and form is unique, instantly recognizable that it could only have come from this one small specific area.

Sand Calcite
stock #22.1-654
Bellecroix Plateau, Fontainbleau, Seine-et-Marne
Ile-de-France, France
6 x 3.3 x 3.2 CM (cabinet)
price: $770


A classic of mineralogy, the sand Calcites from the French discoveries around Fontainbleau have been prized over centuries. This specimen shows perfectly the rhomb form and is complete on all sides. No damage or contacts, Even though Calcite is a very common mineral, this style and form is unique, instantly recognizable that it could only have come from this one small specific area. The main large rhomb shows well the penetration of smaller crystals and is a less common habit from this famed locale. We rarely see this fine sharpness in one of these, many are more rounded or less distinct.

Sussexite on Calcite
stock #24.1-116
N Chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
6.2 x 3.9 x 2 CM (cabinet)
price: $440


A very fine and distinctive Sussexite from a very unusual locality, the famed NChwanning Mine of South Africa. The specie is best known from Franklin, New Jersey and is named for the county there. However the New Jersey specimens are normally massive or asbestos form fibrous clusters. This is very different with radiating balls of distinct crystals perched on bladed pink Calcites. This is a fairly rare Manganese Borate mineral almost never seen outside of Franklin, and almost never in attractive specimens. This is a nice exception to that rule. Excellent addition to any suite of Manganese minerals or NChwanning species.

Grossular on Clinochlore - fine Piedmont specimen
stock #22.FC-013
Ala Valley, Lanzo Valley, Turin
Piedmont, Italy
4.8 x 3.7 x 2.6 CM (miniature)
price: $1750


A killer of Piedmont style Garnet on Clinochlore. Perfect, well-formed and well-exposed Grossular crystals up to 1.2 CM. contrast with blue green matrix. Fine condition Italian specimens with such large size crystals from the high elevation Rodingite zones are prized by collectors the world over. These rank as some of the world’s best for the specie. This piece has several Garnets in an epitaxial cluster but also has perfectly isolated crystals as well. The bright luster makes this hard to photograph but in person it is very impressive and eye-catching.

Lepidolite- very fine crystals with Elbaite
stock #22.1-549
Paprok, Kamdesh District
Nuristan, Afghanistan
5.3 x 4.4 x 4 CM (small cabinet/ large miniature)
price: $590


Perfect hexagonal crystals of violet Lepidolite in a cluster with small gem clear Tourmalines. The Tourmaline (Elbaite) is a pale pink to almost colorless and are in perfect condition as well. Even though Lepidolite is not uncommon, good crystals are surprisingly rare. These are sharp, thick and most have the flat termination faces hosting a circular zone of white microcrystalline Feldspar. Both unusual and esthetic, a choice and attractive specimen of Lepidolite crystals.

Copper coated by Chrysocolla
stock #24.1-069
Bou Nahas Mine, Oumjtane, Anif Cercle, Tingir Province
Draa-Tafilalet Region, Morocco
9.4 x 6.7 x 1 CM (cabinet)
price: $150


Native Copper crystals in a flat, lace-like branching form that are covered with green Chrysocolla. In fine condition as seen, from a locality that has begun to produce some very attractive Copper secondary minerals and an occasional nice Copper like this. The Chrysocolla is a fairly thick outer coating but it is still possible to see the shapes of the underlying copper crystals, including some spinel twin forms. Choice.
