Exquisite 3.5cm doubly-terminated Indicolite crystal emplaced on a clear Quartz crystal. The Tourmaline is gem quality for it's entire length, undamaged, with a good medium blue color (not too dark!) that alternates in intensity and shows great blue color well under any lighting without the need for any backlighting. The Quartz itself is fine and also interesting due to inclusions of white Dolomite crystals. No damage, repairs, or restorations. Ex. Mike Keim.

Dark, slightly irridescent blue Argyrodite over Pyrite. Ex. Philadelphia Academy and William Vaux collections (with some old, corroded labels). Rare, historic Argyrodite specimen. Argyrodite is one the rarest of the silver species, a germanium containing silver sulfide.

Glassy Red Beryl crystal on a Rhyolite matrix. The crystal forms a sharp hexagonal prism of 6 x 4 mm with a flat termination that is undamaged but shows etched growth. The crystal is very gemmy in the central area.

Large, water-clear Quartz crystal with a shorter crystal leaning into it and a few other crystals crossing at the base. There is some cloudiness in the base, but the upper 9cm is amazingly water-clear and perfect. Undamaged. Ex. Gene Reynolds, Cliff Krueger, Mike Keim collections.

Pyrite from Merelani is noted for it's high luster and complex form, and this specimen is one of the best I've ever owned, one that I've held in my collection for years. It has large size, top metallic luster over all surfaces (others have matte luster in areas) and the color is wonderful. It's a tall oval in shape, well crystallized all around with a point of contact on the base. There is some damage as to be expected on most Pyrite from this locality, and areas where contacted from Graphite and Calcite. Trigon growth hillocks are present on some of the faces. There is even Tanzanite and Diopside grown into the base. Due to the high luster it was hard to photograph and you will find this to be much better in person than the photos. Ex. Mike Keim.

Pyrite from Merelani is noted for it's high luster and complex form, and this specimen is one of the best I've ever owned, one that I've held in my collection for years. It has good size and complex form, and more complete than most. It's well crystallized all around, even on parts of the base. Has areas where contacted from Graphite and areas of attached Graphite. Ex. Mike Keim.

Scuptural, aesthetic Copper crystal from the Rocklands Mine. Well crystallized all around with a beautiful form and good patina. Good from either side.
