Beryl- Gem clear hollow crystals
Mulane Pegmatite, Alto Ligonha District
5.6 x 2.1 x 1.3 CM (cabinet)
A pair of parallel gemmy Beryl crystals (light green) with very distinct central canals that run the length of the prisms. The crystals are terminated at the tops yet the central hole is perfectly in the middle of the terminations. There are striations running the length of the central canals that are clearly seen through the otherwise transparent crystals. A fine example of this uncommon and interesting oddity. Similar to some hollow crystals that were found in Brazil in the nineties, these show wider central canals and they are all the way through the crystal. An older piece formerly in the Steve Chamberlain collection, his label states he obtained this in 1977 from the Dossert collection. Unlike anything else I have seen from Mozambique and a super interesting, attractive Beryl!
Beryl var. Emerald -Classic locale
Malyshevo, Ekaterinburg, Ekaterinburgskaya Oblast
4.5 x 3.2 x 2.6 CM (miniature)
From this famed old locale in the Urals, a terminated Emerald crystal on matrix with deep green color. A few smaller Emeralds are also present but the main crystal (1.7x 1.5 CM) is dominant on the specimen. The large flat termination face is dusted with a sparkling dusting of Mica that adds some interest as well. The history of the minerals from this region is an incredible story that is still ongoing today.. This is a good representative piece with some edge translucence but not cutting worthy. Not at all a common item in the mineral marketplace, yet quite affordable..
Bertierite w. Stibnite
Herja Mine, Chiuzbala , Baia Mare
15.7 x 6.2 x 5.4 CM (cabinet)
A super, large display specimen of a specie that is not often considered as a display-worthy mineral! A brushy tree like spray of well defined Berthierite with fine steel- grey color and very bright luster. In perfect condition and good looking on all sides, this is an older piece from the Herja Mine, ex Carter Rich and William Hladysz. This area of Romania produced what are by far the worlds best of the specie and this is a top percentile specimen that is certainly among the very best pieces. Now that the mines are closed this is certainly to be considered a classic. Much better in person.
Deep red small crystals of Proustite scattered on a complex mix of tiny yellowish Quartz crystals. A nice thumbnail of a "noble" Silver mineral that has several different habits showing. With magnification some broken areas are noted which is typical for most Proustites but all in all this is a cute and fairly rich specimen from a classic locale. Ex. Wm. Hladysz collection, he acquired this in 2003.
A choice old Harz Mountains pink Apophyllite ex Erastus Corning (1794-1872) and Cornell University collections. Corning specimens are quite rare in themselves, he was an important politician, industrialist and the city of Corning is named for him. His interests were broad and included a small but fine mineral collection. Likely a pre 1865 specimen, very glassy with fine color and in remarkably fine condition despite the age of this piece. Fine old pink Apophyllites from St. Andreasburg are one of the most desirable 19th Century classic from western Europe. Excellent value for the size quality and provenance
A choice Almaden Spanish Cinnabar with great provenance as well. See the excellent Mineralogical Record article on the locale for in depth background. Vintage specimens of this quality are almost never available, this one is rich red, sizable and with old labels including Alvin Schortmann and John Marshall collections. The Shortmann label tells he had this prior to 1939, though this is likely far older. Johns collection card reads "Group of fine sharp xls in center of matrix. The British museum specimen on display is nowhere near as good as this piece." John wrote that in 1991 when he obtained the specimen. A label from Joe Vajdek reads " Very rare, Irreplaceable classic".
The display area also has a number of tiny Calcites scattered on the Cinnabar, which is in several forms and habits. Some micro chipping exists as it does on practically all pieces but his is not noticable without magnification, and is equal to or better than many well known, published pieces. Before the availability of Chinese Cinnabars these were prized as the best specimens in the world.
North Vernon, Jennings County
4 x 2.5 x 2.3 CM (miniature)
An amber to cognac color Calcite perched on smaller crystals. Excellent transparency and form, this area of Indiana has a very distinctive habit to the Calcites that were found here in past years. The faces have a glassy yet melted look some are slightly rounded while others are perfectly flat. Close to perfect but a few tiny edge rubs are noted, though not easily found with naked eye, the display presentation is excellent.
Outstanding form and patina with excellent iridescent hues on this Tongshankou Chalcocite. This discovery from 2013 was big news in the mineral world, the Chalcocites were unbelievable, unlike any found before. The supply has long ago dried up and these have become scarce and very desirable. This is an excellent, colorful example in perfect condition. Chalcocite is a fairly common, important Copper ore but almost never seen as anything but massive deposits. Good crystals are rare and much prized and these rounded tree-like growths are really only known from this one very unusual find. Choice.
