16.9 x 15.4 x 5.9 cm. This is a very unusual Indian specimen featuring a plate of pink stilbite peppered with dozens of transparent, zoned rhombs of calcite - with dark phantoms in their interiors.
17.4 x 14.3 x 8.9 cm. A large specimen of heulandite and stilbite crystals that have been included by celadonite to give them their very pretty and unusual green color. The crystals sit on a slightly concave matrix of solid pink stilbite.
12.9 x 7.4 x 5.8 cm. A large specimen of bizarre green stilbite, which gets its color from inclusions of celadonite. This specimen features two large clusters that look like flower blossoms, on a thin matrix.
12.1 x 8.4 x 6.5 cm. A gemmy, doubly-terminated apophyllite crystal measuring 6 cm is at the center of this impressive and sizeable Indian combo specimen, surrounded by smaller crystals and blooms of light peach-colored stilbite.
6.9 x 5.2 x 3.9 cm. In a shallow pocket in an aggregate of orthoclase crystals peppered with flecks of biotite is a shallow pocket with glittery crystals of transparent stilbite - an uncommon Arkansas zeolite specimen. Collected by Don Heins in 2004.
5.4 x 3.3 x 2.9 cm. A gorgeous combo of sprays of peacock-blue cavansite in a perfect balance with shimmering, pearly crystals of stilbite.
9.5 x 6.2 x 5.7 cm. A fine, symmetrical, light salmon-pink heulandite fan is centrally placed in a curved vug coated with drusy chalcedony. The heulandite is accompanied by a blocky, colorless calcite rhomb, which is beautifully accented by a lustrous, salmon-pink stilbite blade. Both the heulandite and calcite crystals are preferentially over-coated with a sparkly druse of chalcedony.
17 x 10 x 5.5 cm. A fine plate of large (up to 5 cm) blocky crystals of Apophyllite on a bed of light peach Stilbites. The Apophyllites have an excellent, striated luster and are beautifully zoned - medium green cores and clear terminations. The Stilbites also have a radiant pearly luster and good attractive habit. Ex. Charlie Key.
6 x 6 x 3.2 cm. A fine specimen of uncommon pseudo-cubic Calcites. The Calcites are gemmy with a rich honey color, and sit nicely on pink Stilbites. The largest Calcite is 1.1 cm on edge. Ex. Charlie Key.
7.7 x 7 x 4.2 cm. A fine cluster of thick, 3 cm long orange-pink Stilibite crystals on a plate of clear gemmy Apophyllites. The near-radial pattern of the Stilbites creates a "flower-like" cluster. Ex. Charlie Key.
14.1 x 11.9 x 7.1 cm. A big, blocky apophyllite crystal, measuring 4 cm x 5 cm, is at the center of this large Indian specimen, accented by cream-colored stilbites and some smaller apophyllites.
11.0 x 8.0 x 6.3 cm. A rare and unusual 2.4 cm, hoppered apophyllite crystal centralized amidst pearlescent, fat stilbite blades on this cabinet combination piece from Khadakvasia, near Poona, India. Ex. Phil Scalisi Collection.
16.3 x 15.8 x 7.5 cm. A large, pretty zeolite plate from India featuring a bloom of peachy stilbite on a bed of glassy, sparkly apophyllites, which themselves sit on grey quartz. The stilbite cluster measures about 9 cm across.
11.9 x 8.5 x 6.8 cm. Sharp apophyllite crystals to 5.5 cm with peachy stilbites. The apophyllites have transparent green centers with colorless terminations on the ends.
13.8 x 6.3 x 3.4 cm. A relatively large, incredibly pretty plate of peacock-blue clusters of cavansite scattered amongst pearly-white blades of stilbite.
