Quartz Var. Chalcedony Ps. Calcite on Chalcedony Stalactites
Cabinet, 10.3 x 5.7 x 4.0 cm
Jalgaon, Maharashtra, India

This unusual stalactitic specimen of chalcedony was formed around slender threads of another mineral, resulting in a very pleasing sculptural configuration. At the top, chalcedony has replaced a scalenohedral calcite crystal, as well. The chalcedony is lustrous, translucent, with a colorless to gray color. The longest stalactite measures 8.0 cm in length. There are also a few crystals of pearlescent, white stilbite attached. The largest of these measures 2 cm across. Odd, yet beautiful!
