The Prehnites of India are perhaps not as spectacular as Prehnites from other locations but some specimens do have remarkable beauty. Typical Epistilbite crystals are prismatic, usually elongated along the c-axis. The terminations of the crystals are often frosted, giving the specimens an attractive soft gray appearance. Many of the Indian Calcites are quite complex, showing several generations of growth. The complexity of Indian Calcites can be seen in specimens such as a Honey colored Calcite on Chalcedony coated White Calcite .
Calcite often forms the matrix or substrate for aesthetic specimens.
Although generally the Apophyllite that is associated with Calcite is water-clear, occasional specimens of Calcite with Green Apophyllite are found. It dries out and flakes away, sometimes within hours of collecting. We rarely see well formed crystals, but occasionally we will see a nice soft white remnant within a geode. Some of the finest Powellite specimens in the world come from Maharashtra State. Powellite is rare and large aesthetic crystals are priced as high as any of the minerals from India.
