Tarnowitzite Tarnowitzite Tarnowitzite Tarnowitzite Tarnowitzite

Large matrix specimen loaded with gemmy Tarnowitzite crystals. The matrix is coated by micro crystals giving a sugary luster, and some of the larger crystals have red areas of inclusions. In excellent condition overall as I could only find a couple missing crystals. Good on both sides.

Sugilite Sugilite

New find of chatoyant Sugilite. Prized Sugilite specimens were first those with small crystals, then later came specimens with fibrous crystals - and now this style, the first I've ever seen like it. This is a solid seam of fibrous, chatoyant Sugilite, reportedly the best quality (though not the biggest) out of only about 5 significant pieces found. A rare and unusual specimen, but could you imagine cat's-eye Sugilite cabachons? Weighs 55.6 grams.

Chalcotrichite in Calcite with Malachite Chalcotrichite in Calcite with Malachite Chalcotrichite in Calcite with Malachite Chalcotrichite in Calcite with Malachite

Two generations of Calcite with the later generation showing incredible orange coloration due to inclusions of Chalcotrichite. To add to the color explosion are fibrous bright green crystals of Malachite. Peeking out in areas is the first generation of Calcite, which is green due to inclusions of Dioptase This is old material from the collection of longtime African dealer Rob Smith. Sawcut on one side.

Unique thumbnail specimen of star-shaped Mimetite with attached Malachite. Fully crystallized all around with only one tiny point of contact on the backside.
