Rock Candy Mine, Grand Forks, Greenwood Mining Division
10.6 x 7.5 x 5.7 CM (cabinet)
Sharp transparent Barite crystals rising like a chain of mountains above a sparkling landscape of tiny Barite crystals. Bright yellow-orange color with fine luster from the finds several decades ago at the Rock Candy Mine, British Colombia, Canada. Attractive cabinet sized specimen from the collection of John Marshall (his label is included). Close exam shows a few small rough edges on some crystals but most are quite perfect and sharp. For such a delicate, fragile mineral this is in amazing condition. An excellent example from this locale and a nice Barite from any place.
A remarkable and impressive form with hundreds of small Arsenopyrite crystals aligned in sweeping arcs. From the recent finds at the Huanggang Mine in Inner Mongolia, the crystals have a moderate or satiny metallic luster. The presenting display face is perfect, undamaged however the bottom and part of one side is rough. That area is not distracting in normal display.
Fluorite - penetration twins
Xianghualing Mine, Linwu County, Chenzhou Pref.
12.7 x 7.3 x 5.7 CM (cabinet)
A very unusual, older (2002) Chinese Fluorite from Xianghauling with several distinct penetration twins. Some white zoning is seen on close exam but these are mostly a uniform mint green, transparent to translucent, and vividly fluorescent. This is very unlike most of the later finds from this area, the UV response is also very rare. The largest crystals have very classic habit twins up to 2.7 CM across. This somewhat resembles English Fluorites as this twinning if far more common from there. We have seen only a handful of this sort from China and this is a very choice example as seen.
Small bright red transparent Rhodochrosite crystals scattered in an open vug on a dark matrix. The Rhodochrosites are perched on tiny fingers and knobs of Goethite with a few small crystals of pale colored Fluorite making a nice addition. Minimal damage, the specimen displays well; it could also be trimmed to a miniature size but we like it just like this. Ex Charles M Noll collection, his label is also included.
Pointed blue green blades and needles of Vivianite in a radiating cluster. Formed on a soft Sandstone matrix this is an older piece (the original labels say "Ukraine") from well before the Russian annexation of this area. The crystals are in fine condition, there is some contacting but no real damage. With good lighting the color is a dark blue to green but otherwise this does look darker. Nicer in person, a good, delicate spray habit example of this famed find.
Classic Garnet specimen from the Malenco Valley of Italy collected in the late 1890's. There are some pale yellowish and darker green Andradite crystals on this matrix which has a tiny bit of adhering Asbestos. This is more Demantoid than Topaziolite despite the label that accompanies the specimen. The Garnets are translucent to slightly transparent, typically showing some rounded areas and what seems like face etching. These are well-exposed from the matrix and in good condition. Garnets from this very old mineralized zone have an immediately recognizable look unlike any others. A choice old European garnet.
Small but sharp, brilliant, transparent Cerussite crystals from Tsumeb. A super specimen in person, ex Willy Israel collection which he obtained from Clive Queit. This is a reticulated sixling habit where one arm is much larger than the others. The luster and inner reflections are difficult to see in photos but the color and light refraction of gem Cerussite is well seen in person with this piece. Nearly perfect, magnification shows some small inobtrusive chips but for this famously fragile and delicate mineral the condition is really fine.
A choice old Tilly Foster (USA) Chondrodite specimen. Several dark red Chondrodite crystals up to 1.3 CM stand on a matrix of Chondrodite and crystallized Clinochlore. This is from the important early collection of Wallace Gould Levison. His collection ledger notes he obtained this on May 9th, 1897 on a trip to the mine, purchased from a Mathew McClosky, we presume to be a miner. A copy of this ledger page is included. Some contacting and small chips are noted but the condition is still much better than typical. Tilly Foster specimens are highly sought after classics, hard to find in any quality, this piece has the very rare addition of a clear early provenance.
