Prehnite -sharply crystalized
stock #A-16-480
Jeffrey Mine, Asbestos
Quebec, Canada
2.9 x 1.8 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $330
Spring 2017

A textbook form presented in a cluster of sharp crystals. Well crystallized prismatic Prehnite is quite rare and the best in the world are from old finds at the Jeffrey mine. This specimen is perfect by naked eye with only very tiny contacts and chipping found with 10X magnification. A delicate pale green that looks almost white in some light, this is just a whisker too large to be a thumbnail but could be trimmed to fit if desired. No stains or encrustations, just lustrous bright Prehnite.
Caledonite, Linarite etc with Leadhillite (type locale)
stock #15.1-534
Leadhills, South Lanarkshire
Strathclyde, Scotland
5.3 x 3.6 x 3 CM (cabinet)
price: $560
Spring 2017

A sizable and colorful old specimen of Caledonite with crystals to 4mm mixed in a massive, platy mass. The matrix is a mass of Leadhillite and altered galena and hosts areas of other Lead species including Pyromorphite, Linarite etc. While several crystals are reasonably sharp and transparent when magnified , the overall look is a "melted", opaque appearance. Leadhills is the type locale for both Leadhillite and Caledonite, this is a particularly good coverage and size.
Cornwallite with Azurite - classic USA
stock #16.1-762
Tintic District
Utah, United States
3.8 x 3.7 x 2 CM (miniature)
price: $390
Spring 2017

A rich vug of nearly pure Cornwallite surrounded by Azurite. Outstanding form with fine and distinct sheaves and spherical masses. With several old labels dating to the late 19th century, (Erinite was the old group name for Cornwallite and Chalcophyllite). Dense coverage with no damage, an unusual and attractive USA specimen of this uncommon Copper mineral.
Brucite on Andradite
stock #16.1-326
N'chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
7.8 x 6.4 3.2 CM (cabinet)
price: $700
Spring 2017

A pearly blue ball of Brucite crystals sits neatly on top of a contrasting Andradite matrix. An attractive setting for this usually unimpressive mineral, this is quite esthetic and in fine condition. The matrix is well crystalized on all sides, so it is a floater and the Garnets are especially lustrous on the back side. This would be a really nice specimen of Andradite on its own, but with the Brucite this is especially choice.
