8.2 x 5.7 x 3.1 cm. The apophyllite spray, which measures 5 x 4 cm, is very 3-dimensional in person. The stilbite crystals are a fine accent to this excellent specimen.
6.9 x 5.3 x 4.5 cm. 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.
10.3 x 8.0 x 4.5 cm. This 8.0 cm tall stilbite, is lustrous, translucent, and exhibits a pastel salmon color. It sits on a matrix of white, drusy, chalcedony. For accent, at the base of the stilbite, is a 4.0 cm tall, glassy white fluorapophyllite crystal.
10.8 x 9.5 x 7.8 cm. The best viewing angle for this specimen shows a 3-dimensional upright stilbite "bow tie", 8.0 cm in length, with a pastel salmon color and great luster and translucence. The matrix is a thin veneer of basalt. On the side of the specimen is a light emerald green fluorapophyllite, whose termination is just visible here (main photo).
7.0 x 6.4 x 5.2 cm. Surrounded by sheaves of pearlescent stilbite, to 3.0 cm in length, is a large, translucent, lustrous, emerald green crystal of fluorapophyllite, terminated by a basal pinacoid and measuring 4.0 cm across.
9.7 x 7.5 x 6.0 cm. This is a fine mineral specimen, not only for the two generations of stilbite and a rocket ship-like fluorapophyllite, but also for the superb balance of the whole specimen. The whole specimen is on a matrix of basalt and small white chalcedony clusters. A large, cauliflower–like cluster of ivory colored, lustrous, translucent, stilbite, to 7.0 cm, is offset by pearlescent, blades of stilbite to 2.5 cm across. Then there is the 5.5 cm tall, lustrous and translucent, pastel green fluorapophyllite crystal alongside.
11.9 x 8.3 x 7.4 cm. Clustered on a matrix of spiky, white chalcedony are a group of lustrous, translucent, light salmon stilbite crystals, to 7.0 cm across. Adjoining is a cluster of mint green, brilliantly glassy and lustrous, translucent fluorapophyllite crystals to 3.5 cm across.
17.9 x 13.2 x 10.3 cm. A fine combination specimen featuring a spray of gemmy, glassy, mint-green apophyllites to 2.2 cm leaping out as accent atop an off-white colored cluster of stilbite bowties. The apophyllites all have the same unusually modified basal termination of some of the recent apophylllite finds here, differing markedly from apophyllite terminations of most other pockets in the past. No damage, complete-all-around: the stilbites are 100% 3-dimensional and complete around their terminations which hang off either end.
22.4 x 19.8 x 8.6 cm. This remarkable specimen features a 10 x 7 x 6 cm twinned calcite still in situ in a gently curving concave vug of superb, 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 apophyllites and into the calcite, illuminating it from seemingly more angles than you would expect. A 3-diminsional twin of this caliber, on matrix so nicely balanced, is not at all common.
7.6 x 6.6 x 2.9 cm. Emanating from a wreath of lustrous, cream-colored stilbite crystals, to 3.5 cm across, is a spear shaped, pristine, and transparent, light emerald-green fluorapophyllite crystal. The length of the fluorapophyllite crystal is 6.5 cm in length and it exhibits very good luster. The termination is very sharp. This is an older piece obtained some 20 years ago at the Pandulena Hills Quarry. Ex. Bill and Elizabeth Moller Collection.
13.8 x 8.3 x 6.7 cm. This is a very fine specimen. Nestled among crystal clusters of doubly terminated, gemmy, colorless fluorapophyllite, to 5.0 cm across are lustrous, brown, saddle shaped crystals of heulandite, to 5.5 cm across. The color contrast is wonderful.
7.8 x 6.0 x 4.1 cm. Vivid, azure-blue kinoite microcrystals are festooned on sparkling apophyllite-coated matrix on this fine, highly representative specimen of the species and locale. Kinoite is a rare copper silicate and this is very rich specimen.
12.5 x 9.5 x 6.5 cm. A stunning, cabinet-sized radial cluster of highly lustrous, colorless to green, cubically-tipped apophyllite crystals, from a now infamous find of 2001. You simply cannot get them on the market, any more. These have a special place in the midst of other Indian minerals and some people call them "disco balls" for good reason. They sparkle incredibly in person. The "tail" of pearlescent stilbite blades and a ball of scolecite are fine accents.
13.9 x 9.5 x 6.8 cm. Certainly one of the rarest and most desirable Indian species are the pink apophyllite crystals from the one-time 1970s find near Poona. Glassy, gemmy, pink, pyramidal crystals to 2.5 cm line the vug on natrolite-covered basalt matrix on this striking cabinet specimen. The terminations are exceptionally gemmy. Very few were available and I have never seen one in this size and quality. In person, these sparkle like glass and are a vibrant pastel pink hue, hard to capture at the same time in the photos here.
9.2 x 7.0 x 7.0 cm. A fine mounded cluster of lustrous, translucent, color-zoned, blocky apophyllite crystals beautifully accented with pearlescent stilbite blades from recent finds at Nasik, India. The largest crystal is 3.4 cm and many of the crystal corners have octahedral modifications. Complete-all-around and pristine. Ex. Wes Parker Collection.
