5.8 x 4.2 x 3.5 cm. An outstanding, classic combination piece from the Goboboseb Mountains in Namibia. The wheel-shaped Prehnite cluster is superb - good luster, attractive mint-green color, and translucent. It is an amazing 2.8 cm across. Attached is a sharp white 2.3 cm Analcime crystal. Both rest on euhedral Calcite and Quartz crystals. Charlie loved prehnite and had a large subcollection of the material. Ex. Charlie Key Collection.
3.8 x 1.8 x 1.6 cm. A fine and very attractive Molybdenite crystal from the famous locality of Onganja. Note the rare, 3-dimensional, exceptionally thick crystal morphology. The large crystal is 2.2 cm across, and bipyramidal. The luster is superb, and the habit of this layered crystal is quite interesting - half is a complete layered crystal, while the other half shows multiple complex crystal growth. Complete, but on a smaller scale. And the Molybdenite is on matrix, no less. A fine specimen. Ex. Charlie Key.
12.7 x 6.2 x 6.2 cm. An amazing combination piece of a gemmy Topaz with a huge gemmy Smoky Quartz from the well-known locality of Klein Spitzkopje in Namibia. The gem-clear Topaz is actually 9.5 cm long as it penetrates through the Smoky Quartzes, with 4.8 cm exposed. It is 2.6 cm wide. The gemmy Smoky is 12 cm long and 4.6 cm wide. There are three smaller attached Smoky Quartzes. Ex. Charlie Key.
13.5 x 11.9 x 7 cm. A fine golden-yellow botryoidal Fluorite, an amazing 5 cm across, nestled in a bed of sharp Quartz crystals. The translucent Fluorite has the normal matte finish, and both the color and size are very impressive. The Quartz crystals are also impressive - many are at least 2 cm across. A classic for this locality, one of the few where fluorite of this habit occurs in nature for some reason. Ex. Charlie Key.
3.8 x 3.5 x 2 cm. A superb euhedral ilmenite crystal with Smoky Quartz. Ilmenite crystals from this region do not often have well-defined crystal faces, but this single crystal has excellent faces and lustrous striations on the reverse side. Very typically, this has an outer orange-tan coating of alterations (we are not sure what). An excellent specimen for this combination. Rare find, rare material for Erongo. Ex. Charlie Key.
7.7 x 3 x 1.9 cm. An interesting combination of four doubly-terminated Quartz crystals, included with Hematite. Each Quartz crystal is sharp, pristine, very lustrous, and gemmy. Ex. Charlie Key.
3.8 x 3.2 x 2 cm. A fine single crystal of Amethyst from the Brandberg locality in Namibia. The luster is superb, and the Amethyst phantom in the crystal is a rich deep purple that is sharp and attractive. Ex. Charlie Key.
5.3 x 2.3 x 2 cm. An exquisite basalt vug lined with sparkly drusy Quartz, and containing excellent crystals of Epistilbite and Chabazite. The Chabazite is over 1 cm across, has superb luster, and appears to be twinned. The Epistilbite crystals are up to 1.3 cm tall and have good luster. A great combination piece. Ex. Charlie Key.
6.7 x 4 x 2.5 cm. A classic Tongbei specimen - Smoky Quartz crystals generously covered with gemmy Spessartine Garnets. The Smoky QUartzes are up to 1.3 cm in size and have good color and luster. The beautiful spessartine Garnets are gemmy, deep orange, and have the superb, striated luster that makes them so special. Ex. Charlie Key.
6.6 x 6.4 x 4.0 cm. Monazite gets its name from the Greek word "monazein", which means "to be alone", in allusion to its isolated crystals and their rarity when first found. Monazite is usually found in granitic pegmatites, but these crystals are found in hydrothermal tin veins where is an absolute absence of Thorium (usually a trace element in Monazite). This is a remarkable, very well crystallized, very rare, specimen consisting of sharp, lustrous, translucent, orange-pink, twinned crystals on Monazite-(Ce) measuring up to 6 mm on Quartz crystals on matrix. The crystals actually perform a color change in different lighting ranging from orange-pink to a white/yellow depending upon the light source. This piece is from the same mine for which this material was discovered along the Contacto and San Jose veins in this mine and was first described by Sam Gordon and Mark Bandy.
4.4 x 3.4 x 2.3 cm. This is so reminiscent of England it’s uncanny. This miniature size specimen is loaded with dozens of superb, sharp, lustrous, pyramidal crystals of Quartz that are included with Hematite / iron oxide to produce some of the most intense red Quartz crystals I’ve seen from Bolivia. I don't have a more specific locality for this material, but unfortunately that can be the nature of the beast with Bolivian minerals. I know the piece is indeed Bolivian in origin. It was purchased by Brian Kosnar directly from the miner who collected them while Brian was on a buying trip in Bolivia.
5.8 x 4.6 x 2.7 cm. A superb specimen of a rare phosphate from a world-famous locality. Zanazziite is a Hydrated Calcium Magnesium Iron Aluminum Beryllium Phosphate. This piece hosts several large, sharp, lustrous, well-formed, translucent, olive-green crystal groups of Zanazziite which are aesthetically sitting on a matrix of crystallized Rose Quartz and white Quartz. The largest Zanazziite aggregate measures 3 mm across. This specimen is over 30 years old and is from the original find from the 1970’s. Ex. Richard Kosnar Collection.
A cluster of whopper quartz crystals, all terminated, with only a single contact on one of them. Fine, large quartz clusters of such size are not common from Eastern Europe, so this is really quite special. It is complete all around on teh terminations! Ex Dr Gary Hansen dealer stock , at least 25 years old now. 20.2 x 8.0 x 6.5 cm
Nothing fancy, just a very nice and classic Arkansas quartz! ex. Dr. Gary Hansen dealer stock and not shown since early 1980s. 8 x 5.5 x 3.6 cm
brilliantly lustrous DEEP CHERRY-RED cinnabar crystals to 1 cm on contrasting matrix with quartz. Nice! Now an oldtimer…. ex. Dr. Gary Hansen dealer stock and not shown since early 1980s. 8 x 6.1 x 3.8 cm
