Nice reference specimen
Cute association!
This specimen is composed of several complete spheres of lustrous, translucent, ivory colored Gyrolite atop an earlier brown later, to 2.0 cm across.
Olive green and dark green, bi-colored spheres of Gyrolite , to 1.5 cm across, form a 3-dimensional cluster. The crystal cluster is both lustrous and slightly translucent.
This specimen consists of a cluster of spheres of olive green, lustrous, slightly translucent Gyrolite , to 2 cm across. It is dusted aesthetically with a druse of colorless Apophyllite and super sparkly overall! Most unusual combination, I would say...
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.
5.1 x 4.9 x 2.3 cm. A fine Indian specimen of three olive-green gyolite balls to 2.1 cm on white matrix peppered with smaller gyolite crystals. From the Bombay area quarries, which are now extinct, due to population growth. Ex. Steve Smale Collection.
5.6 x 3.2 x 2.9 cm. A very gemmy, light tan crystal of calcite with fine luster, measuring 3 cm, is surrounded by snowy balls of gyrolite. A very aesthetic combo specimen from the Bombay area.
8.6 x 5.4 z 2.1 cm. A SUPERB and AESTHETIC Indian combination piece from the now-closed Malad Quarry, near Bombay. A large, 3.5 cm, translucent, pastel yellowish-greenish, lamellar gyrolite ball is beautifully set on a sawed plate richly sprinkled with smaller gyrolite and colorless prehnite balls. The white matrix is coated with beige, drusy prehnite. This is one of the very finest Indian gyrolites that I have seen. Ex. George Feist Collection #1855.
5.5 x 4.1 x 3.9 cm. A blocky, colorless fluorapophyllite, with good luster, sits atop a natural base of light pea-green gyrolite that has formed balls intermixed with gemmy little fluorapophyllites.
3.8 x 2.3 x 1.7 cm. A small piece perhaps, but this features gyrolite of really outstanding quality and unusual yellow-green color. You could mistake it for prehnite, from the translucency and crystallization! Ex. Charlie Key.
7.7 x 6.0 x 2.2 cm. A SUPERB and AESTHETIC Indian combination piece from the now-closed Malad Quarry, near Bombay. A large, 3.5 cm, translucent, pastel yellowish-greenish, lamellar gyrolite ball is beautifully set on a sawed plate richly sprinkled with smaller gyrolite and colorless prehnite balls. The white matrix is coated with beige, drusy prehnite. Ex. George Feist Collection #1855.
15.3 x 8.0 x 5.4 cm. A fine large cabinet combination specimen from Jalgaon, India. Three, superb, translucent, olive-green gyrolite balls to 2.3 cm are set on matrix with one, centrally located, beautiful, okenite puffball and a scattering of rare, snow-white laumontite blades.
9.0 x 6.5 x 5.5 cm. Three velvety-soft, snow-white okenite puffballs are adjacent to two gem, very light amber calcite crystals attractively placed on the front of a pristine and aesthetic cluster of intergrown, snow-white gyrolite balls. The gyrolite is superb - seldom do they get so lustrous or so stark and snowy white. Ed Ruggiero purchased this piece from the Zweibels of Mineral Kingdom in 1980, while the famous Malad Quarries near Bombay were producing such fine specimens. The quarries are now closed, due to population growth. Ex. Ed. Ruggiero Collection.
5.2 x 4.0 x 3.4 cm. This old specimen from a now-closed quarry features really fine, gemmy, relatively large crystals of the extremely rare zeolite species, Yugawaralite. To 1.5 cm in size, these are quite important. They also happen to be beautiful, and high in lustre and gemminess. This specimen came from the personal collection of an Indian dealer, in the mid-1990s.
