Pyrrhotite replaced by Pyrite and or Chalcopyrite
stock #6.2-566
Yaogangxian Tungsten Mine, Yizhang County
Hunan, China
5.5 x 4.2 x 3.3 CM (cabinet)
price: $120
Spring 2017

An oddity from the great Yaoganxian mine, sharp rosettes of Pyrhotite (rare at this locale) that are coated by secondary Sulphides and associated with Chalcopyrite and Pyrite. The Pyrrhotite has been partly or entirely replaced by what is likely pyrite but could also be Chalcopyrite. Both species are on the speciems matrix. Delicate and well formed this was part of a small find we obtained at the mine in 2003. I have not seen these since then. Uncommon and a nice example for any good Yaogangxian suite.
HOLD Plumbogummite -replacing Pyromorphite
stock #HOLD 16.1-281
Daoping Lead-Zinc Mine, Yangshao
Guangxi, China
6.2 x 3.7 x 4.4 CM (cabinet)
price: $890
Spring 2017

The Daoping mine is famed for Pyromorphites, among the worlds best, but new discoveries of Pumbogummite are by far the best on the planet. This specimen has fine form, great color and display impact, it is far above average for the mine and on its own just a beautiful specimen of a previously rare and expensive mineral. Nearly all of these have considerable damage, staining or crude areas. This one has a lot less damage than usual, the main crystals are complete and perfect, and the color is a killer bright blue. Damage limited to outer edge and two other spots. A choice display piece that is a modern classic and stands out from the typical specimens of this find.
Smithsonite- gem clear crystal ex Clive Queit
stock #16.1-201
Otjikoto Region, Namibia
2.4 x 2.2 x 1.5 CM (thumbnail)
price: $180
Spring 2017

An unusually clear crystal of Smithsonite rising from a mass of smaller Smithsonite crystals. The main crystal is facet grade transparent which is not typical, and the pale pinkish color is also very nice. Not perfect but undamaged by naked eye, magnification shows some tiny broken crystals on the matrix and a contact/ cleave on the main crystal. If you are not a perfectionist this is a very good specimen at a reasonable price for quality.
Diamond - Three crystals, different colors and habits
stock #15.1-655
Kimberly, Francis Bard District
Northern Cape Province, South Africa
.3 x .3 x .2 CM largest (thumbnail)
price: $300
Spring 2017

A group of three Diamond crystals, each with a slightly different color hue and very different crystal habits. From an old collection, these total 1.55 Carats. The largest crystal is a penetration twin cube the middle size is a cube with half of its faces having hopped indents and half with growth hillocks and the thirst seems like a cyclic discoidal twin. Under magnification many small modifications and extra faces are seen. Sharp and a nice suite of Carbon!
Fluorite -new find
stock #16.1-768
Hameda, Jorf, Er Rachidia Province
Meknes-Tafilalet Region, Morocco
7.9 x 5.8 x 3.9 CM (cabinet)
price: $300
Spring 2017

Glassy bright yellow Fluorite with sharp transparent cubes in an esthetic cluster. From a new find in the Hamada area that has produced much better than previous specimens. Choice display specimen with distinctive habit and color. All of the main crystals are perfect, undamaged which is rare in a Moroccan Fluorite.
stock #15.1-452
Ilfeld, Nordhausen, Harz Mts
Thuringia, Germany
5.7 x 4.1 x 2 CM (cabinet)
price: $320
Spring 2017

A fine, old German Manganite with very lustrous metallic crystals. Looks good on all sides but the "front" is a bit better. Typical crystal habits reaching to 3.3 CM. Some contacts and breakage keeps the price very low for one of these classics yet this still displays quite well.
Pectolite and Natrolite
stock #13.1-360
Jeffrey Mine, Asbestos
Quebec, Canada
5.8 x 4.3 x 2.3 CM (cabinet)
price: $135
Spring 2017

A sharp and complex specimen, with mostly gemmy Pectolite crystals radiating in all directions. Undamaged and choice. Pectolite is not often an attractive mineral, this specimen is an exception to the rule. Fr4om the incredible Jeffrey Mine, this is even more impressive when magnified.
Cuprite- large well crystallized mass.
stock #16.1-355
Red Dome Mine, Chillagoe, Tablelands Region
Queensland, Australia
7.8 x 6.2 x 3.8 CM (cabinet)
price: $460
Spring 2017

A sizable pure mass of Cuprite, nearly all crystallized with individual crystals reaching 1.5 CM. A few small vugs have some hairy Cuprite V. Chalcotrichite, in excellent condition overall, this is a rich specimen from a classic locality. Better in person.
