Large cluster of Azurite from the famous Chessy mines of France. These mines are long closed and I understand these specimens were found in the 1800s. This specimen is out of an old collection built in the 1960s and 70s and has minor amounts of attached Malachite.


C389 - Stellerite $ 200 DISCOUNTED 40% OFF TO $ 120

Yellow crystal groups of Stellerite with the largest 3.5cm across. Radial groups of crystals that get wider as they extend out. The form reminds me of the fat back tires you sometimes see on motorcycles. Close inspection reveals a highly lustrous surface of interlocking crystals. I got this at the 2018 Tucson show and I only saw five specimens of this style with one dealer.

C272 - color change Dravite $ 150 DISCOUNTED 40% OFF TO $ 90
Nchongo, Umba Valley, Tanzania
thumbnail - 1 x 0.9 x 0.8 cm


color change Dravite from Nchongo, Umba Valley, Tanzania [db_pics/pics/c272a.jpg] color change Dravite from Nchongo, Umba Valley, Tanzania [db_pics/pics/c272b.jpg]

Single Dravite crystal exhibiting the 'Usambara effect' color change (named after nearby mountains). This is a different type of color change than the Alexandrite effect, where the color changes in different types of lighting. In this case, the Dravite crystal appears green in normal lighting, however when a single light source is transmitted through the crystal, at a certain thickness, a sudden color shift from green to red is observed, while less thick areas remain green. Well terminated, complete crystal. This is often demonstrated by taking thin slices of crystals. If, for instance, the critical thickness is 3mm, you can take two slices that are 2mm thick each, and each will appear to be green. If you overlap them slightly, creating a combined thick ness of 4mm the area that is overlapped will appear red. This crystal is dark but very transparent, gem quality.Transparent red with strong backlighting.

Glassy single Apatite crystal from the famous Siglo XX Mine. The Apatite appears to be clear but colored grey due to inclusions of needle-like crystals of Jamesonite. Old dealer price was $400 on this unusual thumbnail.

B928 - Chamosite psuedo. Almandine $ 260 DISCOUNTED 40% OFF TO $ 156

Intergrown pair of crystals of Almandine replaced by Chamosite (the iron analogue of Clinochlore in the Chlorite group of minerals) from the upper peninsula of Michigan. Good sized with crystals to 3.5 cm (most found were less than 3cm). The old label indicates it was in the Frank Hess collection and identified it as 'Aphrosiderite', however Aphrosiderite is an obsolete name and Chamosite is the correct species name. I only have the Hess label, but this specimen is also shown on the Arkenstone website and indicates it was from the historical garnet collection of SMITH COLLEGE, Northampton, Massachusetts and ex. Dr. Gary Hansen Collection.
