Mound of nearly clear stubby quartz crystals from Malad, Maharashtra State, India. The specimens from Malad are characterized by hollow cores, where quartz crystals grew over tapered calcite (?) crystals, then the calcite was later removed by solution, leaving a hollow core shaped like a calcite crystal. This specimen likewise has the same hollowing. No damage. Measures 2.5 x 1.5 x 1.75 inches ( 6.4 x 3.8 x 4.4 cm).
