Detailed Description This is a great pseudomorph of goethite after marcasite, with sharp crystals all around – highly lustrous and very dark (virtually black). Of the many habits of these White Desert pseudomorphs, my friend Tracy Kimmel used to call this the “mace head” habit – this one is from her collection. In excellent condition, […]

Detailed Description This is a wonderful pseudomorph of goethite after marcasite, with sharp crystals all around. Of the many habits of these White Desert pseudomorphs, my friend Tracy Kimmel used to call this the “mace head” habit. In excellent condition, and top-calibre!   Please Note: the colour representation in the still photograph has been carefully […]

This is a fantastic specimen of the classic “fluorite corner” specimens from Elmwood – an etched fluorite, where the remaining outer corner of the crystal is at the one end, and tapering majority of the piece represents a slice into the central core of the original cube. The surfaces of the crystal are fully crystallized, […]

A lovely specimen of the classic “fluorite corner” specimens from Elmwood – an etched fluorite, where the remaining outer corner of the crystal is at the bottom, and tapering majority of the piece represents a slice into the central core of the original cube. The surfaces of the crystal are fully crystallized, not cleaved – […]

This is a floater galena crystal, complete all-around, with marcasite crystals perched all over it. Both the galena and the marcasite crystals are sharp and have good lustre, with very well-developed crystals. In excellent condition and stands perfectly for display as photographed. From the Tracy Kimmel Collection, this is a super piece! About Tracy Kimmel […]

This is a nice group of Illinois fluorite crystals with honey-yellow cores and outer zones of bluish-purple to deep purple. The crystals are sharp and lustrous with beautiful surface growth features. A few chalcopyrite crystals are present as inclusions within the fluorite, and a few are perched upon the fluorite crystals. In good condition overall, […]

This specimen features sharp, lustrous rutile crystals nestled in bladed crystals of kyanite (coated with goethite-hematite). The rutile crystals exhibit twinning and are a very dark red under good light. From the world’s preeminent rutile locality, these are wonderful crystals!   Please Note: the colour representation in the still photographs has been carefully calibrated and […]

A joined pair of calcite crystal balls – this is a floater with no point of attachment. These calcite crystals are elongated and spiky, and under magnification, some have a dusting of a second generation of extremely tiny calcite crystals on them. There is minor etched purple fluorite in association. In excellent condition overall. This […]

A beautiful deep purple fluorite from the Denton Mine. It’s a gorgeous composite set of cube faces forming a very flat/thin crystal that has recrystallization faces all around the back. This would have detached from fluorite at the rear, sometime prior to the end of the time when the fluorite was still crystallizing. Thanks to […]
