3.6 x 3.3 x 3.0 cm. A stunning specimen that looks like nothing so much as dark tourmalines stuck in a wad of hot pink bubblegum. The color here is maximal for an Afghani morganite, and is much more intense, in person. The crystal is translucent, with some transparent areas, but universally bright and lustrous. The morganite is a floater, complete-all-around and fully terminated. Ex. Laura and Stevia Thompson Collection.
3.9 x 1.4 x 1.3 cm. A totally gem aquamarine, with a fine accent of spessartine at the base. Some pocket clay remains atop. I chose to leave it as a highlight to the form at the termination, which otherwise is hard to photograph as it is so gemmy and clear. Ex. Laura and Stevia Thompson Collection.
3.0 x 1.4 x 1.2 cm. This is a superb piece. It is a very clean, gem clear, transparent, intensely colored heliodor of very high quality from this classic old gem mine. This is pristine, and complete-all-around, and equally gemmy and glassy on the termination, for that matter. Ex. Laura and Stevia Thompson Collection.
18.5 x 13.7 x 8.5 cm. This is a modern classic combination piece from the rich Nagar Valley area of Pakistan which has produced fine pink apatites and more aquamarines…though the combination is even more desired. The specimen weighs over 2 kilograms. It is a tall specimen that could be propped diagonally for height or set flat for width maximization (18 cm on long diagonal if you wish to stand it that way, 14 cm if sat flat on its bottom and not propped up). The main aquamarine is about 2 inches, just under 5 cm, tall. The whole piece is in remarkably good condition. All display face crystals otherwise are pristine, and have lustrous, complexly beveled, beautiful and gemmy terminations that you can look right down into. The pink apatite accents emphasize and complement the color of the blue aquamarines (which is a nice even pastel hue). Lastly, the muscovite is the best color, a very metallic-silvery hue, and the arrangement is elegant as it flanks the aquamarines.
8.8 x 4.1 x 3.3 cm. A beautiful aquamarine crystal from the less well-known Padre Paraiso area of Minas Gerais. The glassy, highly lustrous crystal has vivid blue-green color, textbook hexagonal form and a striking, sharp, modified, pinacoidal termination. The crystal has excellent translucence, as the photo shows. This very fine crystal is complete-all-around and pristine. Ex. Wes Parker Collection. Weighs 195 grams.
3.1 x 1.1 x 1.1 cm. This Aquamarine specimen was mined by Richard Kosnar in the late 1970's and his diggings produced some of the finest color, unheated Aquamarine in the world. Most of these crystals are not gem quality, but this crystal is approximately 90% gem clarity, which is very good for the material. This crystal is a fine, sharp, gem/gemmy, slightly hydrothermally etched, rich blue color crystal of Aquamarine from one of the more obscure localities for the material. Ex. Richard Kosnar Collection.
12.6 x 7.8 x 7.8 cm. Matrix specimens of Aquamarine are still fairly uncommon in the world, and to find an association piece such as this is uncommon. This specimen hosts a solitary, euhedral, gem quality, water-clear, sky blue color prismatic crystal of Aquamarine measuring 3.4 cm long which is protruding from a matrix comprising, sharp, well-formed, distinct, and lightly frosted crystals of Smoky Quartz which are associated with contrasting snow-white crystals of Albite and minor Muscovite.
2.7 x 2.5 x 1.9 cm, 2.9 x 1.8 x 1.6 cm (2 largest specimens). Sharp, brilliantly lustrous, etched beryl from the Himalaya Mine where beryl is fairly uncommon. 3 thumbnail specimens, all little jewels. They have the faintest hint of pink to them, but really are closer to colorless than to morganite. Ex. William Larson Collection.
2.4 x 1.6 x 1.3 cm, 1.9 x 1.7 x 1.3 cm. Two unusual, straw-yellow beryls from a rare county locale. Ex. William Larson Collection.
4.6 x 2.8 x 2.8 cm. An unusual goshenite specimen from this briefly-mined claim, now sadly exhausted (at least for practical purposes, and without a lot of dynamite). The Cryo-Genie Mine produced a huge variety of gem crystals in its brief lifetime in the late 1990s and early 2000s, among them this fine miniature from the "goshenite pocket". A stoudt single crystal is accented by schorl tourmalines here. Unusual. Ex. William Larson Collection.
7.6 x 5.5 x 3.4 cm. A major piece for the locale. This is a special morganite, and the only good one I have personally seen for sale from this locality. It is a sharp morganite, of a crystallographic quality normally reserved for Afghani material…and almost unheard of from San Diego County. The white albite association in particular makes it look Afghani, though it is not. Ex. William Larson Collection.
2.1 x 1.7 x 1.3 cm. A nice locality piece from this remote, seldom seen locale. Ex. William Larson Collection.
2.5 x 1.3 x 1.0 cm. A nice locality piece from this remote, seldom seen locale. Ex. William Larson Collection.
4.7 x 1.1 x 1.0 cm. A superb, gem quality, 10-gram aquamarine of intense color and with good clarity - exceptional for San Diego County aquamarine and long prized in this collection. Ex. William Larson Collection.
Thumbnails. A beautiful set of unusual gemmy crystals that nobody really would believe was from the county if it came with anything other than the pedigree of the biggest San Diego County collector and miner of our time. All have glassy lustre, and glisten, in person. Bill Larson collected these specimens himself at this now-defunct locality, which is now part of Indian casino land. Ex. William Larson Collection.
