These are old grain grinding stones from India. The chakki or low table had two stones, one fixed on the bottom and one on top that would be spun by a wooden handle (smaller hole in stone) to grind the grain. The flour was then collected inside this open wooden table for the days use.
Mounted on a stand they make beautiful sculptural pieces. Made of granite with an incised half round patterns in the face of the stone. This stones depth is not consistent as it tapers from 2-1/2″ thick on one side to 1-3/8″ thick on the other for a difference of 1-1/8″ (see photos in slide) .
