From the incredible finds at Penas Blancas come some of the worlds clearest Quartz. Remarkable optical-grade clarity, fine condition and with a few edge modifications;(extra faces). The striations are very distinct and add a prismatic effect from some angles. We have had been to visit these prospects and mines, selected top specimens and are pleased to offer these fantastic prisms. Much more transparent in person.
Azurite- slender form, complex cluster
stock #17.1-789
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oriental Region,
Morocco
6.6 x 4.2 x 2.8 (cabinet)
price: $650
Late Summer 2018
All Azurite crystals with no matrix to speak of. This slender jackstraw habit much like a modern art sculpture was distinctive for the Touissit mine more than twenty years ago. The Azurites are of a complex habit and have several different styles of jagged terminations. In fine condition despite the delicate form, a few bits of adhering gossan are noted in some of the nooks and crannies. A choice and now classic specimen this style Azurite is noticeably unlike any from other localities.
Pyromorphite -Rare locality
stock #0694-JM-554
Electric Point Mine, Gladstone Mountain, Leadpoint, Stevens County
Washington,
United States
4.2 x 3.7 x 2.8 CM (miniature)
price: $110
Late Summer 2018
This is the only Pyromorphite I have seen from this locality, therefore I could say it is the best one I have EVER seen! Actually it is fairly rich, a nearly pure piece of Pyro, but clearly not fine display grade, with modest crystals and some vugs of botryoidal crusts. Ex John Marshall Pyromorphite Suite obtained by trade with the Royal Ontario Museum in 1972. A rare locality piece with good color and some nice areas.

Late Summer 2018
Gem clear crystals of honey colored Sphalerite with a few small white Calcites as accent on massive matrix. Very fine large thumbnail with fine bright luster. Better in person, these are now a modern US classic, but not often available. Ex. Hladysz collection, several crystals show pronounced smooth curved faces.
Meterorite- Sikote Alin

Paseka Village, Sikhote-Alin Mountains
Primorsky Kray,
Russia
4.3 x 3.1 x 1.5 CM (miniature)
price: $190
Late Summer 2018
A choice 53 Gram Sihkote-Alin meteorite that shows the pitting, ablation and fusion crusts on all sides, a so called "complete individual". This is one of the most famed meteorite falls from 1947, the resulting Iron meteorite specimens are the coarsest octahedrites known. This piece has sharp and distinct "thumbprints" and the dark color and luster for this fall. Ex John Marshall collection.
Crocoite and Vauquelinite -Type Locality
stock #0654-JM-4287
Berezovsk Mine, Ekaterinburg, Sverdlovskaya Oblast, Middle Urals
Urals Region,
Russia
8.8 x 5.6 x 4.3 CM (cabinet)
price: $880
Late Summer 2018
Very rich, fine old classic specimen (with 4 prior labels) that is well crystalized. Excellent color contrast with the bright red Crocoite and green Vauquelinite, This seems to be a late 18th or early 19th century specimen, (what may be a date of 1895 is on one label but it may also be a collection number). The discovery of Crocoite at this locality dates back to 1763 and it has been renamed many times over the years. The style of specimen and the association of good Vauquelinite is typical of the vintage pieces. Ex John Marshall collection, his collection card and a previous label indicate it sold for $12.00 in 1956, a vast sum for any mineral at that time. The August 2016 Mineralogical record article on this locality offer a wealth of information and several other good specimen photos. This specimen is far beyond average quality with only very minor bruising, most crystals are intact and are well exposed on the matrix. Virtually impossible to find this quality now on the market, better in person too.

Beryl var. Emerald
stock #8.1-389
Muzo Mining District
Boyacá,
Colombia
2.3 x 1.8 x 1.4 CM (thumbnail)
price: $1950
Late Summer 2018
A single fat gem crystal with excellent color, very sharp edges, lustrous faces and fine display impact. 8.9 Grams a few inclusions but with good transparency, this was mined in 2007. A small area of attached shale on the backside/bottom is the only matrix, this is all Beryl. It has gotten very uncommon to find such good single gem crystals in Colombia. Newer methods of treatment, filling and enhancement means these can be consumed by gem cutters for much more expensive jewelry. In excellent condition and better in person.
