Offering an art deco platinum ring with two round garnets with an old mine cut center diamond. Prongs holding the two garnets are gold. My guess is someone in the past took out other stones, probably diamonds and had them replaced with garnets. The top of the ring measures 7/8" x 3/8". The ring is a size 7 and weighs 4.6 grams. Not marked but tested true for 900 platinum, center diamond tested with a Presidium Multi Tester III.
