RUSS-06 - Manganoan Calcite on Sphalerite - SOLD

Just a stunning Dalnegorsk combo specimen. The calcites not only have wonderfully sharp poker-chip form, but a lovely pastel pink color from manganese. They sit on a beautifully contrasting matrix of dark crystallized sphalerite. The calcites are actually like little sandwiches, transparent in the middle and milky-translucent on the faces. Fluorescent orange.

RUSS-13 - Apophyllite on Calcite - SOLD

There are 3 specimens here from this unique find in 2005 at the 2nd Sovietskiy Mine in Dalnegorsk. What you have is poker-chip calcites (to 3 cm) which are covered with small, sparkling crystals of apophyllite. The apophyllites also are also lighting up the surrounding matrix, with a dove-grey color coming through from the underlying (unidentified) mineral, which creates a wonderful contrast with the calcites. SPARKLING AND BEAUTIFUL in person!

The apophyllites also are lighting up the surrounding matrix, with a dove-grey color coming through from the underlying (unidentified) mineral, which creates a wonderful contrast with the calcites.

In person, these compound crystals of calcite are actually a pretty, light golden color, with subtle striations on their faces. The largest measures 6 cm top to bottom. They sit side-by-side on a matrix covered with smaller, lighter-colored calcites. An entirely different form from the familiar "Rudniy calcites" from the nearby Saranovskiy Mine at this locality!

RUSS-25 - Manganoan Calcite (rare form!) - SOLD

These are HUGE, thin, poker-chip calcites, with a faint pink hue from manganese presence, in a gorgeous interlacing cluster. The piece fluoresces bright orange due to teh manganese tint. These crystals measure up to over 8 CENTIMETERS across! The pic with the specimen in-hand shows the show-stopping magnitude of this stunning Russian calcite specimen! This specimen was found in the mid-1980s according to our Russian source, and just came to market this past year from his collection. RARELY do you find manganoan calcite of this habit, for whatever reason that may be. Usually these are stark white and don't fluoresce. Here, though, an exception. And, the latticework form is just exquisite on its own merit.

An absolutely terrific Dalnegorsk calcite mini, a perfect "nailhead" crystal with fine transparency, a perfect pyramidal termination, and a bit of accenting matrix attachment. As a bonus, there is a very noticeable phantom down towards the bottom � you can see its striated termination clearly inside.

This is a VERY unusual Dalnegorsk calcite, due to the extremely uncommon tabular form of the two main "rabbit-ear" crystals (3 cm). The pocket conditions must have been bizarre, because at the feet of these crystals are several crystals that are almost opposite in form: extremely truncated, fat and stumpy, far wider than tall. There is not a "standard" looking crystal in the bunch. All the crystals in this cluster have pyramidal terminations. The piece looks like you took classic elongated English crystals and glued them onto a cluster from China, for a unique look!

Look at this wonderful pastel-pink crystal perched perfectly on a carefully-trimmed matrix! This 6-cm, slightly curved rhomb has a beautiful shimmering, pearly sheen. It is complete and undamaged. Fluoresces orange.

Lovely, well-formed dendritic Mottramite overlaying sharp rhombs of Dolomite and Smithsonite. A close-up of this specimen was in the MR�s Tsumeb Issue, P. 78! A very aesthetic, and clearly important, piece. Purchased in 1978 from famed Tsumeb dealers , Miriam and Julius Zweibel.

Calcite from Tsumeb, Namibia [db_pics/pics/rut303a.jpg]

A superb, lustrous, very 3-dimensional specimen of the classic flattened rhombohedral calcite "discs" from Tsumeb! Each crystal has intricate detailling and patterning along the faces, making it glow in person with lots of light reflections off those planes. Purchased from the Zweibels in 1976

This specimen is small in size but large in stature. The white Calcite matrix is liberally coated sharp acicular balls of light green Brochantite along with smaller spherical acicular Conichalcite that ranges from light to olive green. As a bonus, there is a tiny and gemmy dioptase crystal tucked in a small vug in the base. Such a an excellent specimen, no matter how you size it. Purchased from the Zweibels in 1976

Calcite from Webb City, Tri-State District, Jasper Co., Missouri, USA [db_pics/new09mix/dsc03291.jpg]

Webb City calcites are almost a myth in collecting - so few exist to be seen, and so few good ones exist to be owned. This is a fish-tail twinned crystal of huge size, about the size of a football. These are of a rare, unique style found at the turn of the 1900s, in oldest workings of what was to become the famed TriState district in later years. This area today is a disaster site with slumping, empty old cities atop the old mines.This particular specimen would be a beautiful killer from ANY location, but I think the historic interest as a bonus. It is a nearly pristine, huge twinned calcite with a glowing lavender-pink color when even moderately backlit...presenting just an amazing visual impact wihtout knowing anything about the mineral or locality itself. The only other one like it that i have seen was in the Smithsonian's long-held exhibit on TriState material (photo shown here). I am told by oldtimers that most of this material back in the day when found was split along the cleavage planes to make beautiful calcite cleavage chunks for fun and play. Most miners split them in pieces for gifts, paperweights and the like. I believe this to be one of the most distinct, impressive calcites in importance you can own from a US locality. I had no idea something like this existed on the market to be had, even...until I saw it in the Robert Whitmore collection. He obtained it in an old collection he thinks, sometime in the 1960s. To this day, these remain unique in the world and a major US classic. It is the best piece in the Whitmore collection, some would say, even though it was not from his East Coast focus area.

SF10 - Calcite (twinned) - SOLD

Calcite (twinned) from Verkhniy Mine, Dalnegorsk, Russia [db_pics/pics/sf10a.jpg]

A VERY gemmy, glassy, clear twin of high quality. MUCH BETTER IN PERSON! There is a small bit of pebbly texture on the back face, and this comes through in the pics as looking like inclusions because the crystal is so darn gemmy they show through. In person, this is MUCH MUCH better. It is pristine save for a few very tiny dings on the tip which can in any case be "fixed" with acid if so desired. but, they don't even bother me as a calcite collector myself.

SF15 - Quartz pseudo. after Calcite with Actinolite - SOLD

This unusual, sculptural piece is a one-off I have not seen more of. It is a very interesting and 3-D specimen with translucent, sparkling quartz that has completely replaced the original disc-shaped calcite crystals. Interspersed among the larger crystals are thin, acicular green crystals of actinolite variety byssolite.
