IND13 - Heulandite, Stilbite ON Apophyllite ON Calcite - SOLD

In the galaxy of the many wonderful Indian pieces that we have, this one certainly shines bright. The core of the piece is a stalactite of clear 2-3 cm Apophyllites, which is lovely in and of itself. To cap it off, the core of the stalactite, on which the apophs perch, is an elongated calcite twin coated with drusy quartz that shows through in some spots (the calcite is visible only at the base, the bottom)! Perched along one side is a classic 7 cm peach-colored Stilbite bowtie, with one side-crystal attached for added drama. On top of the stalactite are two beautiful pink Heulandite fans, the largest of which is 4 cm long. And if all this wasn�t enough, the Heulandites and Stilbites are covered with a druse of sparkling Apophyllite crystals, which make the crystals appear as if they were covered by the pristine snow of Vermont. An absolute killer, MUCH BETTER IN PERSON, and far from the common variety.

Calcite from Jalgaon, Maharashtra, India [db_pics/pics/ind17b.jpg]

This is a rather amazing, elongated calcite rhomb over 16 cm long! That is over 6 inches, folks! Not only do you have a crystal habit that is unusual for India, but the luster is excellent and the crystals range from translucent to clear. MOREOVER, there are flashes of color iridescence , on the surface (micro-inclusions of oil, maybe?). There is one contact point along the side, which has little impact on the visual beauty of this specimen, and it is fully and completely 360-degree terminated atop. The quality of the crystal actually enhances the honey-brown color, making this an aesthetic, unusual, and important specimen.

Calcite from Jalgaon, Maharashtra, India [db_pics/pics/ind18b.jpg]

Dramatic and razor-sharp cityscape complex of honey-brown Calcite rhombohedra with excellent luster. MOREOVER, there are flashes of color iridescence , on the surface (micro-inclusions of oil, maybe?). Most of the edges are very gemmy, and there is but one contact point in one corner. As Calcites go, this in not only quite eye-catching, but unusual and very aesthetic. MUCH MORE DRAMATIC AND 3-DIMENSIONAL in person, like a computer-graphic in 3-D!

IND20 - Apophyllite impaled on Stilbite, on Quartz pseudomorphs after Calcite - SOLD

This is really quite a superb combination piece, featuring a perfect 4 cm doubly-terminated green Apophyllite.Both tips are extraordinary and complete. The luster and the gemminess are excellent. There are also numerous light-pink Stilbite blades with gorgeous pearly luster � many are doubly-terminated themselves! These crystals primarily rest on two masses of very attractive drusy quartz, which themselves rest on the matrix. When you start looking at it closely, you realize that those "masses" of quartz are in fact flattened calcite rhombohedra, completely replaced by the quartz! This is a fabulous and aesthetic specimen.

GEMS IN MATRIX !!! In this case, the open space in the basalt allowed the formation of of a thin layer of drusy, colorless, quartz as well as exquisite, rhombs, of glassy, transparent, colorless to slightly yellow calcite. The largest rhomb measures over 2.0 cm across. This is a most aesthetic and visually pleasing specimen with the highest quality calcite you can expect to get in terms of gemmy glassy clarity!

INDI-17 - Quartz var. Chalcedony ps. Calcite on Chalcedony stalactites - $ 400

This unusual stalactitic specimen of chalcedony was formed around slender threads of another mineral, resulting in a very pleasing sculptural configuration. At the top, chalcedony has replaced a scalenohedral calcite crystal , as well. The chalcedony is lustrous, translucent, with a colorless to gray color. The longest stalactite measures 8.0 cm in length. There are also a few crystals of pearlescent, white stilbite attached. The largest of these measures 2 cm across. Odd, yet beautiful!

This specimen exhibits some of the best attributes of Indian calcite. It is on a thin slice of basalt, it is twinned, and it is well formed with incredible transparency. GEMMY, in fact. In person, it has intense golden color and wonderful luster like glass - really the top quality you could ask for! It is 3-D and complete all around with only the most persnickety of minor wear on a few crystal edges. Most Indian calcites pale compared with the elegance and beauty of the specimen. It is also LARGE - measure it out, imagine its so gemmy you can look through most of it, and that it is so reflective inside it looks like you are gazing into mirrors!

This is a nifty Indian combo specimen. On a matrix of basalt, drusy, white, quartz formed first followed by gray spheres of calcite, to 1.75 cm across, then glassy, colorless, quartz, to 2.5 cm in length, and lastly, balls of white gyrolite, to 3.25 cm across. The gyrolite has a matte luster with superb translucence. Rarely do you see such large aggregates of this species, and so it is significant as well as nice for the display qualities.

Rising out of a calcite matrix are several bi-colored flluorapophyllite crystals. The bases of some of these crystals are a pastel green which merge into gemmy, colorless, terminations. The largest crystal measures 3.5 cm in length. Unusual on the calcite! And, much flashier in person...

Cavansite, Stilbite, Calcite from Wagholi Quarry, near Poona, Maharashtra, India [db_pics/pics/indi-61a.jpg]

This unusual specimen exhibits three generations of mineral, staring with a matrix of tan, drusy, stilbite, upon which grew a cluster of royal blue, cavansite measuring 1.5 cm in length. Encrusting the cavansite is a generation of colorless, gemmy, calcite crystals, to .2 cm across. This latter encrustation gives the underlying cavansite a strange, candy coating, effect.

This is a rosette of royal blue, lustrous, translucent, Pentagonite crystals with an occasional spike of an individual crystal, to large size at .75 cm in length. It is encrusted with a druse of pearlescent, stilbite crystals. VERY RICH Pentagonite specimen for the price!

A basaltic matrix with a pearlescent, druse of stilbite, act as the host for two rosettes of royal blue, translucent, cavansite, to 1.3 cm across. Jauntily perched on top of the upper cavansite rosette, is a transparent, light, amber colored calcite crystal, measuring .7 cm in length. Amazing aesthetics!

The unusual sky blue color, of the nestled cavansite rosette, is imparted by the large number of small, colorless, lustrous, and transparent calcite crystals which cover the cavansite. All of this is in a vug of lustrous, ivory colored druse of stilbite. Unusual!

This is an outstanding and somewhat bizarre example of calcite from the trap rocks of India. An almost pristine, 7.0 cm tall, lustrous, transparent, colorless, calcite crystal is on a matrix of basalt. The rombohedral calcite crystal has inclusions of chalcedony?, and exhibits preferentially etched modifying faces. It looks as if it is about to ooze off its stalk, like melting ice cream. In person, its MUCH BETTER and very , very bizarre and unusual!

INDI-97 - Calcite (twinned) on Apophyllite with Stilbite - $ 6500

This remarkable specimen features a 10 x 7 x 6 cm twinned calcite still in situ in a gently curving concave vug of top-quality, gemmy apophyllite. The calcite is pristine and the apophyllite as well, except only its periphery along the plate's edges. The piece really "sparkles" in light, which reflects off the apophs and into the calcite, illuminating it from seemingly more angles than you would expect. A 3-diminsional twin of this calibre, on matrix so nicely balanced, is NOT at all common, and I get a piece of this style and quality only about once every 2-3 years
