Indian Iron Tantric Lingam

Copper and brick, patterned like a dried riverbed seen from above.

This tantric lingam is from Narmada River, Madhya Pradesh, India. It is quartz crystal & iron. The article describes Banalinga as chalcedony, a cryptocrystalline quartz with iron oxide deposits, and says scholars link their naturally occurring markings, considered spiritually auspicious, to meteoric iron. Wide, glossy oval in coppery brown with branching red patches that spread over the upper body. Greenish flecks and pale marks gather near the lower center. The silhouette closes neatly at both ends. It is 10.5 inches high and 6.75 in diameter.

Mapped in rust and a little green.
