This is a really superb Mother Of Pearl Dish, Mounted on Three White Metal Feet.
I have no idea where the dish is from or how old it is, but it is a fabulous piece of Mother Of Pearl, with variable colours, very bright when you rotate it in the light. It is etched around the border with a simple, foliate pattern.
The dish is 15.6 cm in diameter, approximately 3.3 cm tall, and weighs 183 g.
