Silver and black brass belt buckle

This 2 tone belt buckle has a nice eye appeal. I am not sure if the cameo is stone or porcelain. Yhe silver and black has a nice effect on the light. I do not clean nor polish the items we find. I figure this will polish up nicely and pop even more. The buckle is about 3 1/2 "x 2 1/4". It is new old stock. Still having its original box. The lable on the box is for a business that has not been open in years. I assume this is from the 70s or 80s. If you have any questions feel free to message me. Remember if you are interested in saving money on the item or also on shipping ----> Be sure to bundle items or make me a reasonable offer. Thank you for looking at my items lot 3
