A sizable and very fine cabinet specimen of well-crystallized Brewsterite from the type area for the specie. Brewsterite is the less common analogue of Heulandite and can be Sr or Ba dominant. This specimen is almost certainly the Sr dominant version though not tested. This has hundreds of well-formed crystals which are transparent to translucent and very lustrous. Ex Hitchings collection this is an older specimen that was obtained in trade. Excellent undamaged condition.
Yellow Prehnite in a crystalline ball from the Loanhead Quarry, Scotland. A single gem clear Apophyllite crystal is a fine contrast. From the Les Hitchings collection, this was collected by him in 1974 during an extended trip to Scotland where he spent weeks digging in the Glasgow area. This was the best Prehnite he obtained.
Esthetic, vintage Cerussite with many of the crystals dusted by tiny Pyromorphite needles. The bright yellow Pyromorphites add an attractive color to the Cerussites From the classic Leadhills area, there are numerous unidentified micro crystals in several vugs as well. An older specimen, ex collections of Ernest Chapman, George Croad and others. In fine condition, the delicate Cerussites are nearly all intact and by naked eye, perfect.

An impressive dense mass of small Pyromorphite crystals encrusting all sides of the matrix. From the classic Susanna Mine Leadhills, Scotland, this was in the John Marshall collection. Collected by him in 1970 such fine specimens have not been found for decades, it was the end of an era of richly productive field collecting. In fine condition with a deep green color this is simply an attractive, sparkling specimen from a classic locale.
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.
