Goosecreekite is a rare zeolite group species, worldwide and also from the Deccan Traps of India. This is a superb, large, 5.8 cm across, spherical aggregate of wedge-shaped crystals with milky white color and a silky luster. The huge goosecreekite shares the vug with glassy and gemmy, colorless aphophyllite crystals, a rare and unusual combination. Ex. George Elling Collection.

Apophyllite from Jalgaon District, India
Jalgaon District is one of the great modern names in apophyllite collecting: a Deccan Trap basalt locality where glassy, geometric fluorapophyllite-(K) crystals emerge from dark volcanic rock with the kind of sculptural contrast collectors remember. The best pieces combine water-clear to mint-green apophyllite with peach stilbite, brown heulandite, sugary chalcedony, quartz crusts, celadonite-rich matrix, calcite, and, more rarely, powellite. The visual language is unmistakably Indian Deccan: bright vitreous faces, steep pyramidal terminations, pseudocubic outlines, and vug-shaped matrix plates that still read as sections of the original cavity.
