Cassiterite
stock #ALEC-22-183
San Antonio Mine
Loayza Province, La Paz department, Bolivia
5 x 3.4 x 2.2 CM (miniature)
price: $140
pre Tucson 2015 update

One of the oldest and best localities for fine Cassiterites in the Americas is the La Paz area of Bolivia. This specimen has well formed and lustrous crystals that under strong lighting show some translucence. The "naked eye" color is shiny black but the "under strong lighting" color is a deep honey orange hue. Some tiny edge chipping exists but most crystals are pristine and the quality for the price is a very good value.
Vesuvianite
stock #17.AL-494
Jeffrey Mine, Asbestos
Quebec, Canada
6 x 4 x 2.5 CM (cabinet)
price: $975
pre Tucson 2015 update

A glassy luster yellow-green cluster of sharp and partly gemmy Vesuvianites. The overall arrangement and esthetics are very attractive, this really displays well. Most of the crystals are sharply terminated and damage free, but a few show recrystallization on old broken surfaces, this can look like damage on a quick glance but it is not. Were it not for the recrystallized zones this would be a far more expensive specimen. Avery good value for the size, color and esthtics.
Vesuvianite -exceptional color
stock #17.AL-482
Jeffrey Mine, Asbestos
Quebec, Canada
2.2 x 1.9 x 1.1 CM (thumbnail)
price: $1000
pre Tucson 2015 update

Rare color and perfect form making this a serious competition grade thumbnail. Even more rare, no damage at 30X magnification can be found. This deep violet to pink purple zoned crystal cluster has great luster and stands out in a display . This is the sort of color and quality that has made the Jeffrey mine a world class locale. This level of quality is rarely available and much sought after.
Diopside (gem clear) with green Vesuvianite
stock #17.AL-490
Jeffrey Mine, Asbestos
Quebec, Canada
5.3 x 3.9 x 4.1 (cabinet)
price: $1950
pre Tucson 2015 update

A killer quality gem clear Diopside cluster with a light sherry color is perched on a contrasting matrix of white Diopside and bright green Vesuvianite. In outstanding condition this has fine eyecatching esthetics, showing the tabular crystals in a perfect stack. Good Diopside from this locale is sought after, these are very uncommon in such quality and condition as they are fragile. An excellent addition to any suite from Jeffrey Mine and a a fine Diopside from anyplace
Acanthite -textbook habit crystals
stock #ALEC-22-178
San Juan de Rayas Mine - Level 407
Guanajuato, Mexico
2 x 1.6 x 1 CM (thumbnail)
price: $130
pre Tucson 2015 update

This thumbnail Acanthite shows textbook forms and habits in sharp, undamaged crystals that have very good luster. A modern classic locale, the San Juan de Reyes mine has been the source for some outstanding silver minerals, this one is an excellent example.
Quartz with Rutile inclusions
stock #ALEC-22-181
Itabira, Itabira-Nova Era District
Minas Gerais, Brazil
4.2 x 2.2 x 1.6 CM (miniature)
price: $50
pre Tucson 2015 update

A sharp and very clear quartz crystal well included with bright golden needles. Most Brazilian Rutilated is from Bahia, this is a less common locale in the Iron Quadrangle of Minas Gerais. Gem grade clarity, there is a contacting, mostly on the back side but the display side still looks fine.
Grossular gem grade with included Clinochlore
stock #17.AL-487
Jeffrey Mine, Asbestos
Quebec, Canada
2 x 1.6 x 1.4 CM (thumbnail)
price: $850
pre Tucson 2015 update

A pretty and fine specimen that is a rather hard to describe and to photograph. A cluster of transparent garnets with a tiny bit of matrix. It is easy to see the matrix through the clear Grossular, and with magnification individual crystals of Clinochlore and what looks like Diopside can be seen inside the crystals. Undamaged, clear and with very, very glassy luster, this has outstanding deep color and is far better in person.
Vesuvianite with Aragonite and possible Pectolite
stock #17.AL-484
Jeffrey Mine, Asbestos
Quebec, Canada
3.5 x 3.4 x 2.4 CM (miniature)
price: $350
pre Tucson 2015 update

An unusual and attractive combo, bright yellowish-green crystals of Vesuvianite are scattered on a branching crystals that were previously identified as Pectolite but now seen to be at least in part Aragonite or similar Carbonate. We have just sent off a sample for anlaysis to confirm. Both the Vesuvianite and the Pectolite/ Aragonite are in excellent condition- no damage can be found even with 40X magnification, which is incredible for such delicate minerals. The Vesuvianites are perched so that it is easy to see they are doubly terminated.
