- Cavansite, Stilbite, Calcite
- Wagholi Quarry, near Poona, Maharashtra, India
- Miniature, 3.4 x 3.2 x 2.6 cm
This unusual specimen exhibits three generations of mineral, staring with a matrix of tan, drusy, stilbite, upon which grew a cluster of royal blue, cavansite measuring 1.5 cm in length. Encrusting the cavansite is a generation of colorless, gemmy, calcite crystals, to .2 cm across. This latter encrustation gives the underlying cavansite a strange, candy coating, effect.
