A very beautiful antique garnet ring. In my personal opinion, the stone itself has an indescribable beauty. Size: Approximately size 11 (Japanese size) There are no hallmarks on the metal, but with antique rings, the hallmark can sometimes be worn away during resizing. Just wiping it with a metal polishing cloth (purchased at a jewelry store) will restore the beautiful gold color. A buyer at a shop said they believe it is gold, not an alloy. For your reference. Because of its beautiful shine, I estimate it to be 9 karat gold or higher. There is no case. I will carefully package and ship it. I would like to sell it to someone who understands antique rings.
