Crystals from India

About

India. The Deccan Plateau's volcanic basalt produces intricate apophyllite, stilbite, and zeolite formations. From the Himalayan quartz found above 15,000 feet to the sunstone of Andhra Pradesh, India's mineral diversity is extraordinary.

The Deccan Traps — a vast volcanic plateau spanning central and western India — are the world's primary source for apophyllite, stilbite, heulandite, and other zeolite-family minerals. The Himalayan ranges yield high-altitude clear quartz with chlorite inclusions and phantom growth. Andhra Pradesh is a major sunstone source, while Rajasthan produces amazonite and the quartzite host rocks that contain ruby fuchsite. Green aventurine, labradorite, and sodalite are also mined across the subcontinent. What makes Deccan Trap minerals unique? The Deccan Traps formed roughly 66 million years ago when massive volcanic eruptions flooded central India with basaltic lava. As those flows cooled, gas bubbles left cavities in the rock. Silica-rich hydrothermal fluids then moved through those cavities over millions of years, depositing the apophyllite, stilbite, cavansite, and zeolite crystals that collectors prize today. The combination of well-defined crystal forms, pastel colors, and complex multi-species associations on a single matrix piece makes Deccan specimens genuinely distinct from any other locality in the world. How does Himalayan quartz differ from other quartz? Himalayan quartz forms at extreme elevations — often above 15,000 feet — in the metamorphic and granitic terranes of the Indian and Nepalese Himalayas. The high-pressure, low-temperature conditions produce crystals with exceptional clarity, and the same conditions that create the mountain geology introduce chlorite inclusions (lending a soft green phantom interior), record-zone growth p
