Very rare and new find from Nasik, Maharastra. Red and green Apophyllite cube with Stilbite.
 
Apophyllite crystalizes as pseudo-cubic crystals, granular masses, natural pyramidal structures, and as druse upon another mineral. The select grades of Apophyllite have been found to occur in Pune, India, primarily in green, white, and clear/colourless forms.
 
Apophyllite was first reported in 1806 by R.J. Haüy. It was names for the Greek words meaning "get" and "leaf", due to its tendency to exfoliate when heated under a blowpipe.

Stilbite, a member of the Zeolite group, crystallizes in the form of aggregates, "bow-ties", plates, globes, radial structures, thin flattened, elongated, tabular crystals, and as rhombic pyramid-type cruciforms. The mineral was first reported in 1797 by J.C. Delamétherie, with the name adopted by R.J. Haüy in 1801. The mineral was named from the Greek word meaning "a mirror" or "to shine", in reference to its brilliant lustre.
