4.3" Peach Stilbite Crystals on Lustrous Heulandite - India
This is a 4.3" wide cluster of peach-colored, bow-tie shaped stilbite crystals scattered across a colorless to green heulandite crystal encrusted matrix, collected from the Deccan Traps (the world largest basalt flow) in Maharashtra, India. The heulandite shows off a spectacular sparkle when tilted back and forth beneath a light source. There is a green hue near the base of many of these heulandite crystals, likely being attributed to the presence of celadonite.

Stilbite is a tectosilicate mineral of the zeolite group that is commonly found in zeolite deposits. Crystals often form flowery bowtie or hourglass-shaped structures and come in a variety of colors. Some of the most beautiful colorations are the pink or peach tints.
Heulandite is a mineral of the zeolite group that also fits within the silicate and tectosilicates groups. It has the general chemical formula (Ca,Na)2-3Al3(Al,Si)2Si13O36 · 12H2O, but the calcium and sodium can be substituted by potassium, barium, or strontium ions. Heulandite crystals will often form as distinctive tabular, radiating crystals with a vitreous luster, and can display a variety of colors including white, green, brown, orange, red, pink, yellow, grey, and black.
