Bob,

That is an exceptional specimen and I am glad that Les Presmyk confirmed what you suspected all this time. Thanks for bringing out some of your older pieces.

Fine, sharp hexagonal Corundum ( v. Sapphire ) crystal with classic blue color is nicely perched atop contrasting white matrix. The Corundum is large at 40 x 32 mm, and thick at over 10 mm, with well-developed triangular growth lines in its face. It is in excellent condition.

GW001692.JPG
 Mineral: Elbaite on Quartz (var. smoky quartz)
 Locality:
Malkhan (Malchan), Krasnyi Chikoy, Zabaykalsky Krai, Russia
 Dimensions: 75 x 67 x 65 mm
 Description:
A fine, classic Russian Elbaite crystal with that cranberry, rich red color you so rarely see, is partly enclosed in a sharp, translucent greyish-smoky Quartz crystal, measuring 56 x 55 x 43 mm. The Elbaite measures 34 x 16 x 15 mm, is lustrous and partly gemmy, with areas of translucence. The base of the smoky Quartz is wrapped in blades of white Albite (var. Cleavlandite) and silvery Muscovite. Several small, gemmy pink Elbaite crystals are perched on the Quartz. The base of the tourmaline shows yellow and cranberry zoning. The specimen shows on 360 degrees and is in superb condition, with absolutely no damage.

For some reason, the locality for the corundum above didn't take. It should be:
Ilmen Natural Reserve, Ilmen Mts, Chelyabinsk Oblast', Southern Urals, Urals Region, Russia

Thanks all. This was my payment for doing some consulting work in 1994 on the initial open-pit project at the Red Cloud. I can be found on street corners with a cardboard sign advertising my "will work for rocks" program.

PostPosted: Mar 17, 2015 22:33    Post subject: Bob's rocks - Rhodonite from Huanggang  

...


GW001361.JPG
 Mineral: Rhodonite with Tremolite
 Locality:
Chaobuleng Mine, East Ujimqin Banner (Dongwu Qi), Xilin Gol League (Xilinguole Prefecture), Inner Mongolia Autonomous Region, China
 Dimensions: 130 x 68 x 58 mm
 Description:
Lustrous, flattened blades of Rhodonite form a large subparallel, seemingly doubly-terminated group measuring 130 x 55 x 36 mm, accompanied by a similar perpendicular group that is cleaved on the base. The Rhodonite is mostly opaque and light-pink colored, with portions that are gemmy and cherry-red. Light-brown Tremolite (confirmed by analysis) coats portions of the specimen. Although there is some damage, it is masked by the ragged crystal terminations. This is a nice and large piece from this prolific Chinese locality.

Very interesting association with the rhodonite and tremolite specimen. I've never seen this combination before.
