This is a superb specimen of goosecreekite, featuring large-for-the-species, highly lustrous, wedge-shaped crystals which are gemmy and clear/white on a contrasting black background. The goosecreekite sits inside a protecting pocket in basalt. Goosecreekite is one of the rarest Indian zeolites, especially in this size and quality, and there is no damage on this fine specimen.
