These three wearable amulet containers are of high-grade silver and were made to be worn as the centrepieces of necklaces.
Each unscrews (often with overly exaggerated screwing mechanisms almost as long as the containers themselves.)
They were made to hold small talismanic or protective verses or anything else deemed to be protective.
The longer, more plain example is likely to be from central India and the other two are from Bihar in India’s north.
Each has suspension loops decorated with silver flowers.
The three have fine wear associated with use and age and lovely patinas and colours.
