Several excellent Apophyllite crystals are scattered amid stilbite crystals of all sizes on this excellent hand specimen. These Apophyllite crystals have the distinction of both excellent tetragonal prismatic crystal form with pyramidal terminations and a lovely green color. They all have a vitreous to pearly luster and are transparent, with noticeable internal fractures and flaws that usually run along the basal plane. The largest of these crystals measures about 0.8"(2.0 cm) in length and 0.4"(1 cm) in width and depth. There is another crystal that is the same length but half as wide and deep that is double-terminated. Many others are visible and undamaged, as well as several that show damage and/or are incomplete due to cleavage. Among these Apophyllites are clusters of flat stilbite crystals with shallow, 2-sided terminations and a pearly luster. These crystals range in size from microscopic to almost 1"(2.5 cm) long, and often have complex terminations whose tips are made up of several tiny terminations. Many of these crystals are aggregated into tight groups. All of this rests on the standard basalt base of all Indian zeolites.

Seven Apophyllite crystals rest on this Indian specimen, amidst a bed of tiny stilbite crystals. These crystals range in size from 0.2 - 1.5"(0.5 - 3.8 cm) and are a pale green color. Two of them are worthy of note, as they are both large and have excellent transparence and form. They occur in a tetragonal prismatic form that is common for Apophyllite, and have four-sided, pyramidal terminations, which is quite uncommon for the mineral when it has the green color. These terminations are tipped by tiny basal faces, and their clarity is magnificent! One of these crystals is quite large, measuring about 1.5 x 0.5 x 0.5"(3.8 x 1.3 x 1.3 cm), and the other measures approximately 0.9 x 0.2 x 0.2"(2.3 x 0.5 x 0.5 cm). All of these rest on a bed of almost-microscopic white stilbite crystals that envelop thin branches of basalt that is possibly stalactitic. These are some of the finest Apophyllite crystals that I have seen.

There are at least 20 tetragonal prismatic Apophyllite crystals on the quartz host rock of this specimen. They are generally in good condition, though a few show obvious cleavage due to impacts. All are colorless and transparent, and most show concentrations of cloudy inclusions near their bases which fade to excellent clarity towards their terminations. Their luster ranges from pearly on the visible cleavage planes to nearly adamantine on undamaged faces. Likely the most interesting aspect of this piece is the quartz base on which these crystals rest; it is in the form of a stalactite that was hanging down in a basalt vug. It shows a rather large breakage surface on one side where it was separated from another stalactite and its tip is broken, but it is nonetheless very attractive and makes for an unusual piece. The quartz crystals that coat this stalactite do not exceed 0.2" (5 mm) in length or 0.1" (2 mm) in diameter and only their terminations are visible, but these terminations show excellent form and reveal the crystals' colorlessness and transparence. There is a small white patch of calcite or microcrystalline quartz on part of the stalactite that glows brightly under shortwave UV light.

Dozens of Apophyllite crystals rest on the stalactitic quartz base of this small hand specimen. These crystals range in length from 0.2" (5 mm) to 1.6" (4.1 cm) and are generally in good condition, as a few of the crystals are either missing terminations due to cleavage or are otherwise damaged. All have excellent tetragonal prismatic form, with well-defined edges and clean faces that possess a pearly-to-vitreous luster. All have steep 4-sided pyramidal terminations and are colorless and transparent. They are moderately clear- all contain cloudy inclusions near their bases and many have internal fractures or structural faults that run along their basal cleavage plane. They are accompanied by scores of tiny, thin stilbites that have a milky-white color and a pearly luster. The quartz base on which they rest consists of two partial stalactites that are partly intergrown. They are coated with a druse of tiny quartz crystals that takes on an almost plumose form. The piece is hot-glued onto a square acrylic base.

At least 10 small Apophyllite prisms rest on the quartz-lined basalt base rock of this hand specimen. These crystals do not exceed 0.6" (1.5 cm) in length and are in generally good condition, though the largest crystal is broken and incomplete and one other crystal is slightly scuffed along a termination face. All have excellent tetragonal form, with well-defined edges and striated but clean faces that possess the standard bright pearly-to-vitreous luster. They are colorless, transparent, and dimly to moderately clear, containing many basal-oriented internal fractures and cloudy inclusions. The quartz crust on which they rest consists a thin druse of countless tiny prisms that coats a pale gray layer of botryoidal agate, which in turn partly coats the basalt host.

Part of a basalt vug contains several well-formed Apophyllite crystals. These crystals achieve dimensions of 0.9 x 0.5 x 0.5" (2.3 x 1.3 x 1.3 cm) and appeare to be in very good condition, as only a few are damaged. However, they are somewhat difficult to study, as most are at least partly intergrown with each other, and all are at least partly coated by clusters and sheaves of small stilbite crystals that have grown off of them. Even with this interference, all have excellent tetragonal prismatic form, with sharp edges and clean faces that possess the standard bright pearly luster. All are colorless, transparent and moderately clear, containing several basally-oriented internal cleavage planes and some cloudy inclusions. There are hundreds of the small stilbite crystals, almost all of which do not exceed 0.3" (8 mm) in length. They are in surprisingly good condition, as only a few are crushed, and line the inner surface of the basalt vug where there are no Apophyllites.

At least 30 Apophyllite crystals rest on this hand specimen. These crystals are generally in very good condition, as only a few are damaged or broken, and reach lengths of up to 1.2" (3.0 cm). All have excellent tetragonal prismatic form, with well-defined edges and clean faces. They are colorless, transparent and have the classic bright pearly luster. Most are transparent and very clear, but several are heavily included and contain basally-oriented internal cleavage planes. They are accompanied by many stilbite blades that do not exceed 0.8" (2.0 cm) in length. These blades are generally in good condition and have good monoclinic bladed form. All of these rest on a base that appears to be made up of agate and masses of more, microscopic, intergrown stilbites.

This large hand specimen consists of several Apophyllite crystals which rest on a crystalline quartz crust. The largest of these Apophyllites has dimensions of 0.9 x 0.9 x 0.6" (2.3 x 2.3 x 1.5 cm) and is rather badly damaged and broken in one area; two other crystals are damaged, and one of these shows obvious cleavage. The other crystals are generally intact and in excellent condition. All have excellent tetragonal prismatic form, with well-defined edges and clean faces that possess the standard bright pearly luster. Their basal faces, however, have a rather dull pearly luster and are very subtly patterned. All are colorless and dimly transparent due to many cloudy inclusions and basally-oriented internal cleavage planes. They rest on a crust or druse of small, well-formed quartz crystals that do not exceed 0.3" (8 mm) in either length or diameter. This druse covers a thin crust of gray banded agate that partly coats the basalt base rock

Several Apophyllite crystals rest on the almost stalactitic quartz base of this specimen. The Apophyllites are in moderately good condition, as several of them are damaged or incomplete due to cleavage, but the largest one is surprisingly intact and has dimensions of 1.8 x 0.6 x 0.6" (4.6 x 1.5 x 1.5 cm). All have excellent tetragonal prismatic form, with well-defined edges and clean faces. They are essentially colorless and transparent, though the larger ones are cloudy and essentially translucent along their prism lengths. They are accompanied by a few small stilbites and countless tiny quartz crystals that coat the "stalactite". A small amount of the basalt host rock is attached to this formation.

This cabinet-sized specimen consists of scores of Apophyllite prisms that line the inside of part of a basalt vug. These crystals are generally in excellent condition due to the protective form of their host, and reach maximum dimensions of 1.4 x 1.3 x 0.9" (3.6 x 3.3 x 2.3 cm). All have excellent tetragonal prismatic form, with well-defined edges, clean faces, and well-formed and truncated basal terminations. They are generally colorless, transparent, and have the standard bright pearly luster. Most are very clear, but the largest crystal (which is much larger than the rest) is quite cloudy, containing many cloudy inclusions and several internal fractures. They are accompanied by many stilbite blades, most of which are broken, and are separated from the basalt host rock by a thin layer of gray-white agate.

Jalgaon, India

Not more than 10 Apophyllite crystals rest on the stilbite-and-agate base of this hand specimen. These crystals are small, not exceeding 1" (2.5 cm) in length, but are in excellent condition, showing no damage. All have excellent tetragonal prismatic form, with well-defined edges and clean faces, and some are doubly-terminated. All are transparent and clear at their termination tips, but cloud to a milky translucence towards their bases. All show a bright pearly-to-vitreous luster. The most exposed and best-formed crystal has a noticeable olive-green tinge that extends from its base to the end of only one of its terminations- the other half of the crystal is colorless. The base on which they rest is made up of intergrown, possibly stalactitic white agate formations that are covered with countless tiny stilbites. A few of these, however, are large, reaching 0.7" (1.8 cm) in length. A small amount of basalt is interspersed with the stilbites at their base.

Poona, Maharashtra State, India

Two separate Apophyllite clusters rest on the basalt base of this specimen. Both consist of crystals that measaure up to 0.5" (1.3 cm) along an edge and are mostly damaged or broken. Where intact, their tetragonal prismatic form is good, showing well-defined edges and clean faces, some of which are caused by cleavage. Their color is pale green, their luster is pearly-to-vitreous and all are transparent but only dimly clear due to inclusions and internal fracturing. They are accompanied by a few broken stilbites and rest on a crust of what is likely more, decayed stilbite that coats the base rock.

Mohodari, Nasik, India

Two large Apophyllites rest on the zeolitic base of this display piece. The larger of the two is more visibly complete and measures about 1.3" (3.4 cm) along an edge. The smaller has visible dimensions of 0.9 x 0.9 x 0.7" (2.3 x 2.3 x 1.8 cm), though half of it is enveloped by the base. Both have excellent tetragonal prismatic form and flat, basal terminations, with small secondary faces that truncate the corners. The larger of the two, along with a few very small crystals that are stacked on the smaller, show a nearly cubic form. Their color is a dull brown-green and their luster is pearly, and all are translucent or opaque. The base on which the Apophyllites rest is made up entirely of what appear to be clusters of radiating natrolite needles. These needles reach lengths of nearly 1.5" (3.8 cm) and are generally in good condition, though many are broken. Those that are not broken are rather heavily weathered but still show good orthorhombic form. A few stilbite blades lurk among the natrolites, along with what appear to be a few large, malformed calcites. The piece has two surfaces that are cut flat - either can serve as a base.

Pashan, Poona, India

This specimen displays hundreds of small aqua-blue transparent apophyllite crystals and a crust of white heulandite (and a few larger translucent to transparent heulandite crystals). The color of the apophyllite is rather unusual - we usually find it either colorless or green. The individual crystals are transparent with a vitreous luster, and generally have rectangular cross sections and roof terminations, although many of the crystals appear to have had a basal cleavage instead of a termination. The contrast of white heulandite, aqua apophyllite, and a dark brown host rock makes for an aesthetic specimen.

Pashan, Poona, Maharashtra State,India

This is a beautiful specimen of green apophyllite on stilbite. The specimen is dominated by a single large crystal which has an essentially square cross-section and multiple terminations. While the bottom 60% of the crystal is cloudy due to internal fractures and stilbite inclusions, the remainder (and terminations) are quite transparent and have a lovely light green color. There are many facets, due both to a stepped growth displaying many little pyramids, and to additional small crystals with similar alignments. The stilbite crystals are colorless, long and thin, with a silky luster. Some of them are perched on the apophyllite at nearly right angles to the larger crystal. A tiny bit of the tips of the larger apophyllite crystals may have been cleaved off - it is difficult to tell, even with a loupe. It may be a growth pattern which has flattened the tips of the terminations.
