♥️Rare Size 9 Vintage High Quality Natural Chalchite Statement Ring

Oval Turquoise look however this size of stone would be a fortune. 3 “ Chalchite stone on I believe gold over. All I can say 100 % is that the metal is an alloy. Due to the quality and weight I believe it could be gold overlaid over sterling or brass - it is difficult to say. I don’t know how to use my metal detector! Intricate beautiful design. No stamps to help define.
