This is a very fine specimen of the uncommon zeolite mineral barrerite, from the only locality that has produced larger crystals. The barrerite crystals are sharp and lustrous and the largest measures 3.7 cm – they are in excellent condition with no damage. They host laumontite crystals as well (these seem not to have been […]

A spectacular cluster featuring top-quality quartz crystals from the Ron Coleman Mine. Supported to stand as photographed, this specimen is striking! The two main crystals are each about 5 cm and they are like bright cut glass, wonderful top transparency and lustre. There are faint tinges of colour from iron – they add to this […]

This is a wonderful top quality specimen of “Herkimer Diamond” quartz crystals on matrix.  This specimen presents such a great balance of size and quality – typically matrix pieces from Herkimer host smaller crystals, and the larger the crystals, usually they are cloudier and more internally fractured with windows and so on. This crystal measures […]

A stunning cluster of “Herkimer Diamond” quartz crystals – these are brilliant, sharp, lustrous and transparent. This specimen makes it easy to see how the crystals from here were likened to cut diamonds.  In excellent condition, no damage. As with all such clusters from Herkimer, the crystals are found in pockets detached from one another, […]

A superb copper specimen from the Northwestern Mine, from my personal collection. This specimen features excellent crystals of more than one habit, including many spinel-law twins and even a few uncommon copper cubes. I acquired it from Don Olson many years ago and it has been in my cabinet ever since. A fantastic piece! Please […]

This is a wonderful old specimen from the Butte mining district. It is a group of parallel-growth amethyst crystals on a core of smoky quartz. The amethyst crystals have highly lustrous pyramidal faces, and the prism faces have very good lustre, but slightly less than the terminations. The crystals are colour-zoned, and translucent to transparent. […]

A beautiful matrix cluster of amethyst from Jacksons Crossroads. The crystals are sharp and lustrous with nice colour and good contrast with the clear quartz and pale matrix. In excellent condition overall – the main crystal and most smaller ones are pristine. One crystal is incomplete, and this is reflected in the price of the […]
