The antique ring was made in the 1800s. It does not have a gold mark but was tested with nitric acid and a "kee" tester to be 10k solid gold. It weighs 4.3 grams and the top measures 1 1/8" from North to South. Set in the center is a hand carved natural coral cameo of a lady facing to the right. Set below the cameo is a small round natural diamond. The ring wears to a size 7 and can be resized. The cameo has no cracks or chips.
