Apatite (purple) - rare locality
stock #22.1-488
Chas de Tavares, Mangualde
Viseu, Portugal
1.2 x 1 x .8 CM (thumbnail)
price: $360
Pre Tucson

A sharp, glass and bright purple Apatite crystal from a very little known locality, found in 2012. Ex Alain Martaud collection this is in excellent condition and shows zoning with the more vivid purple color near the bottom of the crystal and when viewed through the termination the very center has a colorless zone in the core. Portugal is one of the world’s great sources of fine Apatite from the famed Panasqueira Mine, but this locality is over 125 KM to the west and the region has a very complex and different type of mineralogy. Very few of the Apatites from here are purple and most are a lot smaller, this is superb for the locality.

Vesuvianite - Gem crystal
stock #17.1-440
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
Quebec, Canada
3.6 x 1.6 x 1.5 CM (miniature)
price: $3300
Pre Tucson

Vivid color and glassy faces with well-defined striations, this crystal is nearly all transparent and in perfect condition. The color is a bright asparagus green and has a purple to red core. In person the termination looks like a faceted gem, the luster is so bright it is hard to convey in photos. The Vesuvianites from Jeffrey Mine are unique in the world, famed for the colors and perfection. There were quite a few good ones found a few decades ago but very fine crystals like this were never common. Today we see very few and always at very high prices. This is from the F. Spertini collection (the mine geologist for whom Spertiniite is named) and is far better in person with a top display impact. No damage at all. Even on the bottom where it had been naturally broken inside the pocket long ago it is fully healed and re-crystalized. So technically this is doubly terminated and a floater.

Gibbsite- type locale, historic specimen
stock #16.1-125
Richmond, Berkshire County
Massachusetts, United States
7.7 x 5.6 x 5.4 CM (cabinet)
price: $330
Pre Tucson

A fine botryoidal crust of yellowish-white Gibbsite on Limonite ore. From the famed Oren Root collection (with label) which was transferred to Hamilton College in 1835. The Root collection was at that time the finest in the United Staes. This was a new specie named in 1822 in honor of Colonel George Gibbs who was also an important early American mineral collector. This is a very early piece from the type locale, when first found it was misidentified as Wavellite. The specimen left Hamilton College to the NY State Museum collection then to Don Potter and later to Dr. Steven Chamberlain, then to Carter Rich. A long history indeed. Good fluorescence as well, with green and yellow zones LW and midwave shows green to bluish purple and yellow zones.

SOLD Chalcopyrite - exceptional ball form
stock #SOLD 23.1-391
Tonglushan Mine, Daye County, Huangshi Prefecture
Hubei Province, China
4.1 x 2.6 x 2.3 CM (miniature)
price: $0
Pre Tucson

The discovery of these incredible Chalcopyrite balls at Tonglushan (China) in 2018 made big waves in the mineral world. For a while it was rumored these were altered or faked but as they were well studied and examined they have become accepted as fully natural. There is a little resemblance to some old ball specimens of Chalcopyrite from both Bristol, Connecticut and Cornwall, England but these are far more perfect, complete and have a nice patina as well. The find was a one off, no new examples have been found since. This specimen of 5 connected balls shows well the habit and form, is in perfect condition and looks great from any angle. The large ball is 2.3 CM across. A super addition to any Sulphide suite, Chinese collection or to a display that has strange and wonderful minerals!

Beryl var Heliodor
stock #8.AE-996

Minas Gerais, Brazil
3.2 x 2.4 x 1.1.9 CM (small miniature/ large thumbnail (toenail))
price: $450
Pre Tucson

Bright yellow gem grade Beryl crystal 26.2 grams. Essentially this is all fine facet grade that was rescued from cutting some decades ago. This crystal section is well-terminated on one end and although broken on the other end it does show some rehealing there. The color is yellow with an orange hue in most lighting but with a backlight it is a pure bright yellow. It does not seem to be heat treated or irradiated as far as we can tell. Since this came from a gem lot in Minas Gerais (Brazil) we are not certain of the exact mine source, though we have guesses. It is sold as a very nice gem crystal at a great discount for the reason of incomplete locality data. Very fine luster and well-defined striations, this is sold below the value of the facet rough.

Bournonite - fine cogswheel habit crystals
stock #21.1-538
Machocamarco Mine, Cornelio Saavreda Province
Potosi, Bolivia
4.7 x 3.4 x 2.2 CM (miniature)
price: $690
Pre Tucson

Perfect, sharp and very lustrous metallic crystals in a cluster from the important find in 2019 at the Machacamarca Mine. The form and habit really look like fine classic Cornish crystals but these are recent and a small fraction of the cost for a vintage English specimen. The crystals are up to 1.8 CM, undamaged and have textbook perfect morphology. Steel-grey color and an elegant arrangement make this miniature far especially choice. These are certain to be considered classics themselves in the future. Right now this quality and price for undamaged Bournonites is something special.

Elbaite (Rubellite) - vintage specimen from unusual locality
stock #20.1-686
Dobro Vada, Zdar nad Sazavou District
Vysocina Region, Czech Republic
1.9 x 1.2 x 1 CM (thumbnail)
price: $750
Pre Tucson

A small cluster of bright pink Tourmalines with good translucency and gem transparent sections. This has sharp edges, well-formed striations and flat terminations in excellent condition. Any such specimens from this locality are very rare and any good ones like this are simply never seen on the market. This is mounted on a 19th century style turned wooden base. Certainly the best specimen I have seen from this locality but honestly I have seen very few others, and none ever outside of museum collections.

Wulfenite - classic USA locality with unusual form
stock #19.1-989
Mammoth -St Anthony Mine, Tiger, Mammoth District, Pinal County
Arizona, United States
3.3 x 2.2 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $190
Pre Tucson

From the famed Tiger, Arizona locality (Mammoth-St Anthony Mine) This is a quite delicate and well-crystalized small miniature. Wulfenite from Tiger is not rare, it was even at one time used as an ore with hundreds of tons being crushed for Molybdenum. Tiger Wulfenites are known in many habits and often as sizable crystal masses of inter-grown blades. Small, perfect, transparent yellow-orange crystals like these are much less common, showing beveled edges and windowpane form. A nice addition to a Wulfenite suite, Arizona collection, or just for esthetic appreciation.
