pnvn785-Vintage carved mother of pearl brooch

This brooch is constructed from an exquisitely handcarved carved mother of pearl flat back disk, resembling a mandala, or a wheel with 6 spokes. Silver metal pinback is attached by glue and is quite secure. 1 5/8 inch diameter. An old carving with perhaps a more recently attached pinback. There is glue around the pinback, visible on the back side only, and could be carefully removed without much problem.
