Chrysoberyl -twinned crystal on matrix
stock #15.1-836
Colatina
Espirito Santo, Brazil
4 x 2.6 x 3.8 CM (miniature)
price: $350
Fall 2015

A classic form for Chrysoberyl showing an inverted V twin well exposed on matrix. From the finds in the 90's at Colatina, this is a sharp crystal in fine condition. Hard to find any of quality on the market now, this has textbook form. Perfect by naked eye, some micro contacting (mostly on the back side) is evident with magnification.

stock #15.1-314
Tsumeb
Otjikoto Region, Namibia
6.6 x 4.2 x 4.3 CM (cabinet)
price: $850
Fall 2015

Choice, bright blue transparent to translucent Willemite clusters covering matrix. Several have well formed crystals in stacks and isolated prisms. Some areas of Duftite provides a nice contrast. Excellent "wet look" luster, this is in fine condition.

9.1 x 3.8 x 4.4 CM (cabinet)

Fall 2015

An old, unusual and colorful pocket of orange brown Huelandites contrast with a blue green Chlorite lining. Iridescent color is very striking in person and the Huelandites are transparent to translucent as well. 1970's vintage old Campos Novos Brazil specimen that is never seen on the market now.

Gilgit, Gilgit district
Gilgit-Baltistan, Pakistan
4.2 x 1.5 x 1.1 CM (miniature)
price: $380
Fall 2015

Clear, gemmy Apatite crystal with a very faint pinkish hue, that looks colorless in some lighting. This shows a fine internal central wisp with a helix like form. Sharp and glassy, this is from finds a little over a decade ago, there is no damage at all on the prism or termination, it is of course broken on the bottom where it was removed.

Casapalca Mine, Casapalca, Huarochiri Province
Lima Department, Peru
4.3 x 3.3 x 1.9 CM (miniature)

A cluster of Tetrahedrite crystals showing classic forms and with fine patina. From the famed Casapalca mine, this has sharp form with crystals penetrating each other at all angles. Minimal chipping is noted on on some outer edges, most crystals are complete and undamaged.
Calcite on Duftite on Dolomite cast
stock #ALEC-21-020
Tsumeb
Otjikoto Region, Namibia
5.2 x 3.9 x 2 CM (small cabinet/ large miniature)
price: $760
Fall 2015

A fine Tsumeb specimen with sharp, clear Calcites growing on a bright contrasting green Duftite. The Duftite can be seen through the Calcites and the condition is excellent. The underlying matrix is a thin section of Dolomite cast which is itself a very interesting and quite desirable collectable. First rate esthetics.

Superb, textbook form Bournonite twin crystals are perched on contrasting Quartz. Undamaged, (which is rare with Bournonites) and showing fine patina on sharp "cogswheels" and interconnected prisms. Excellent for this locale, this is quite choice from anyplace.
