Pyrite, Calcite from Chenzhong (?), Hunan Province, China [db_pics/mdpics/MD-78874a.jpg]

What a dazzling new discovery! On selective edges of the calcite crystals on this large cluster is bright, golden pyrite - even brighter and more amazing than the pics show! The result is so dramatic and eye-catching! Got these about a month ago from a close and good contact in China who brings us now and then wonderful new things that have not been seen yet....these are SO pretty, in person. We have the best of the lot so far, and are waiting to see if more come! Presented in this update are the three best so far . . . 12.5 x 6.5 x 6 cm

GORGEOUS, PIGEON-BLOOD RED, ruby in contrasting matrix! IN person this has a wonderful classic waxy lustre and much more intensity. Such pieces in matrix are rare, and Bill kept two of them in the suite. 3.2 x 2.5 x 1.7 cm

Beryl (Var: Emerald), Calcite from Coscuez Mine (Cosquez Mine), Muzo, Vasquez-Yacopí Mining District, Boyacá Department, Colombia [db_pics/mdpics/MD-83177a.jpg]

A beautiful spray of gently curved, 2.7-cm-tall emerald curvving up the face of these large, sharp calcites! The piece is very unusual, in its aesthetics, and makes for a very balanced miniature wiht incredibly bright color to it. the sharp form of the calcite contrasts starkly with the classic hexagonal beryl crystals in the middle . The emeralds are a rich and vibrant green, of high gemminess and brightness, and BETTER IN PERSON! 3.9 x 3.6 x 3.2 cm


MD-83308 - Calcite, Sphalerite - - Archived

Calcite, Sphalerite from Elmwood mine, Carthage, Central Tennessee Ba-F-Pb-Zn District, Smith Co., Tennessee, USA [db_pics/mdpics/MD-83308a.jpg]

8.7 x 3.7 x 3.7 cm. A classic, beautiful, doubly terminated, golden-amber calcite crystal set on a small cluster of gemmy, ruby-jack sphalerite crystals from the Elmwood Mine of Tennessee. The form, high lustre and translucency make this a textbook Elmwood calcite. Both terminations are extremely gemmy and the multiple terminations on one end are fascinating.


MD-83313 - Calcite (Var: Manganoan Calcite) - - Archived
2nd Sovietskii Mine (2nd Sovietskiy Mine), Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia

7 x 5.5 x 4.5 cm. An exquisite Russian pink calcite, featuring three large, intergrown crystals with sharp form and pretty pyramidal terminations. The color is a pleasing pink due to manganese content. Such well-formed crystals are uncommon for Dal’negorsk manganoan calcites. Fluoresces orange under UV.

THE PICS DO NOT DO THIS SPECIMEN JUSTICE! It was just very difficult to capture the JEWEL-like nature of this bright, intense calcite crystal. Measuring 1.8 cm, with sharp, glassy faces, it is dramatically isolated at the end of the matrix shard. A very unusual locality for a calcite of this quality! Satisfaction guaranteed – you will LOVE it in person! 4.5 x 2.2 x 2.1 cm

Dioptase, Calcite from Tsumeb, Otjikoto (Oshikoto) Region, Namibia [db_pics/mdpics/MD-83319a.jpg]

Just plain PRETTY! Euhedral crystals of calcite sprinkled with super-bright green dioptase crystals as if out of a pepper shaker! Tsumeb dioptases are always at their best on backgrounds of white calcite – really makes the color jump. In very good shape, with just a color of VERY small and unobtrusive bruises. 6 x 5.2 x 4.8 cm

In a recent update was a specimen from this find that sold four times over. So I am happy to be able to present another piece from the same incredible pocket! Rather than being a single large calcite crystal, this is a profusion of sharp smaller rhombs, but decorated with the same bright, sparkly, colorful iridescent pyrite that made this limited find at the Bor Pit so spectacular. The calcite rhombs measure up to 3.5 cm. 13.5 x 9 x 8 cm

It is hard to argue with how aesthetic this lustrous and complex pyrite crystal is sitting in the calcite. For sheer quality, this is hard to beat for a franklin pyrite, I am told. Beyond that, it is an important historical specimen that, I am told, would have been collected in the mid-1800s. It has Harvard #113145 attached to the side and an old dealer price of $275 on the original thumb box

This exceptionally gemmy piece , with association of calcite, is from the famus finds of the late 1800s and such are very rare! it is a colorful and showy speciment hat is affordable and doesnt break the bank, given that it has some admitted damage between the major crystals and has been priced down accordingly. But, its show value is high and it remains a very rare specimen

Extremely sharp chalcocites to 1 cm perched o ncntrasting calcite matrix make this a very special, unique miniature for the famous locality, mined actively during the Civil War era. Such specimens are few and far between now, and this is a very choice piece, aesthetically.

This is what i call "crystallized leaf gold" because although the shape and thinness at first glance indicate a leafyy gold without form, closer inspection shows flattenned trigons and definite structure to the foil-thick leaf. It has amazing, tinfoil lustre and is incredibly beautiful . You get a lot of display impact and gusto for the price with one of these new Aussie golds, in terms of surface area and pizzazz. This is one of the better miniatures I have seen of the find, especially for the price range. Note the leaf is thin and fragile, so i have stabilized it by sprinkling a few invisible drops of glue to make sure it stays stiffly adhered to the matrix of calcite

A very interesting specimen of charlesite cores surrounded by sturmanite (they are a series, and portions of the crystal are of different species, thus). These crystals are unusually well-formed to be so rich in charlesite, of which they mostly are composed. Charlesite is more white and lighter yellow, while the sturmanite is darker in hue as a general rule.

Calcite after Ikaite

This mineralogical oddball actually features 4.5 cm , orange-brown crystals of calcite pseudomorphing a rare calcium carbonate, ikaite, commonly known as "glendonite". Although these oddities are admittedly esoteric and hard to explain, visually they can be spectacular, like this one.
