A spectacular specimen of negative quartz crystal inclusions in a cut and polished piece of quartz.  They are sharp and well-defined. A gorgeous negative crystal inclusion from the John S. White quartz collection. About John S. White (click here)

This amethyst crystal features several radial inclusions of cristobalite. The amethyst itself is primarily a termination, with the remainder being bounded by angular, tapering striated contact faces. In good condition, minor chipping. The cristobalite inclusions are quite flat in aspect – the large one is very thin. With magnification the smaller ones really look like […]

This amethyst crystal features a group of prominent inclusions of cristobalite. The amethyst itself is primarily a termination, with the remainder being bounded by angular, tapering striated contact faces. It’s in good condition with minor chipping. The cristobalite inclusions look like balls but they are actually fairly flat disc-like cups. The surfaces facing outward toward […]

A beautiful cut and polished piece of quartz hosting incredibly elegant rutile inclusions. (One chip out of a lower corner, around the side from the optimal display angle, in the first photo.) This is gorgeous rutilated quartz from the John S. White quartz collection. About John S. White (click here)  

This is a beautiful polished piece of quartz hosting a myriad of fine silvery rutile crystals (I believe the quartz has been fashioned into this shape). Absolutely wonderful rutilated quartz from the John S. White quartz collection. About John S. White (click here)  

This is a specimen of quartz exhibiting iridescence on select crystal faces. Natural iridescent quartz of this kind (also called “iris quartz” and “rainbow quartz”) has been known from the Deccan Traps since the nineteenth century. Analysis of these crystals has determined that the iridescent z faces of the crystals have periodic microscopic surface ridges, […]

A sharp, lustrous doubly-terminated quartz crystal from the John S. White collection. One of the pyramidal faces is an unusual shape and orientation, also a different texture – I wonder if it is rehealed – it’s very neat. In excellent condition, the bottom termination has minor chipping. A nice and different specimen. About John S. […]

This specimen hosts hematite inclusions – some appear to be spheres or disks, and a few are amazing “hematite nails”. The quartz has red hematite tinges and the piece overall is an attractive cabinet specimen aside from the inclusions. There are a few epidote inclusions as well, and groups of lustrous epidote crystals perched on […]

The quartz crystals comprising this specimen host bright red phantoms and beautiful micro plumes of bundled epidote crystals. There is also a cluster of brilliant epidote crystals perched on the quartz at one end. In excellent condition. Photographed by Jeff Scovil in the days of slide photography, the slide is included with the specimen. This […]

A great piece, with Cumberland habit quartz crystals full of astrophyllite needles. The quartz crystals are sharp and highly lustrous. In excellent condition. This is a fantastic specimen from the John S. White quartz collection. About John S. White (click here)

A sharp, lustrous quartz crystal with green fibrous inclusions. The inclusions form a column up the middle of the quartz crystal, and the column isn’t straight – it looks a bit like a green tornado. The inclusions have been analyzed using Raman by John Rakovan – analysis was conducted through the prism face and also […]

A sharp, lustrous quartz crystal with green fibrous inclusions, in a column running up its centre. Sits perfectly, as the base is a flat cut. The inclusions have been analyzed using Raman by John Rakovan – analysis was conducted through the prism face and also where they are exposed at the cut base, but no […]
