Topaz on Quartz with Muscovite etc
Sakangyi-Kyauk-Pyat-That, Mogok, Pyin-Oo-Lwin,
4.7 x 4.2 x 2.8 CM (miniature)
Several glass clear, colorless Topaz crystals in perfect condition are sticking out of a Quartz crystal matrix. From the Pegmatite of Sakangyi, which had been the source of the best of the Myanmar Topaz, but is now idle. In fine condition, this is a nice example of the occurrence and looks fine from several angles.
An nice older Chinese specimen of the dark transparent Cassiterites from Ximeng that are now very uncommon. These lustrous crystals on contrasting matrix show both twinned and untwinned forms. These are a dark brown to almost golden on some edges and are prettier in person. This find was unlike any other Cassiterites found in China, being more similar to the best from Bolivia, yet still recognizably different.
A choice and quite perfect example of the Yellow Tipped Quartz from the now famous find at Cabiche, Colombia. The Quartz crystals are gem clear with very bright yellow tips and a few wispy white inclusions near the terminations. The esthetics of the arrangement is very impressive in person and in exceptional condition as seen. This small find has been big news in the mineral world, this piece is far above average quality and about as fine a miniature as can be found.
Wardite -superb matrix crystals
Rapid Creek, Dawson Mining District
8.3 x 4.4 x 3.1 CM (cabinet)
From the noted John Marshall collection, this is an killer Wardite with fine, sharp and lustrous crystals perfectly arrayed in a distinct line. The Marshall collection card from 2003 states " Superb crystals on matrix, the display specimen in the British Museum is nowhere as good as this". Obtained from Gregory, Bottley and Lloyd, A great Wardite from anyplace the crystals reach 1.7 CM and are transparent in parts.
A stout Quartz crystal nested on and included by long crystals of dark green Epidote. The Quartz is a light milky green color but still transparent, the crystals of Epidote are clearly seen inside the Quartz. For ten years we have found occasional Quartz with Epidote from this region, but always badly damaged, still the potential looked exciting. This piece is from a new small find we were able to obtain in Colombia recently, these are by far the best specimens so far, this is a choice example. We hope for more in the future but that could be a long while!
A complex open vug in crystalized Albite hosts bright red gem clear Manganoneptunites along with Pectolite needles and Siderite, Rhodochrosite etc. While the individual crystals are best appreciated with magnification, this ihas color enough to be a display specimen, a good addition to any St Hillare suite. Often Manganoneptunites are dark, almost black or are crude crystals, but these are bright and perfectly formed.
Exceptional and super esthetic, the baby blue druse of clear Quartz crystals are richly colored by Shattuckite balls they have grown on and are included by. These contrast nicely with the bright green Malachite crystals. Looks even better in person, this from the find five years ago at Kaokoveld, nothing quite like this has come up since. A super display piece for any cabinet this Copper secondary specimen has top color, luster and form.
A fine well crystalized example of this rare and usually unattractive specie. From the Scalisi collection, there are just not many of these in existence, this has large somewhat etched and crude crystals with a few tiny rough spots seen with magnification. With very strong (40X) magnification some very tiny Rhodochrosite rosettes and what seems to be Shigaite are spotted. The largest crystal is 1.6 CM across . The habit of this piece on one side looks like the type from Franklin NJ, but the other side looks from the Kalaharie Mn fields. Not a beautiful mineral to most people, but a good example and very hard to find
