For your consideration is this chunky colorful Jay King ring. I believe he used sponge coral, charoite and lemon turquoise from my research on him and the stones he used. This is a best guess. It is a bold ring with nice cut outs in the sides. Signed with his DTR China 925 logo. The ring has patina and nice age.
It is a size 10 and 1/2. The face measures 1 and 1/8 inch top to bottom.
