This Art Deco vintage black onyx ring has a small 2mm hand cut diamond in the center. The ring weighs 3.5 grams of 10k yellow gold. It is marked, but has been tested as 10k yellow gold.
The rectangle shape face measures 14mm by 10mm.
Ring size is sized at a 5.5, but can be sized by my jeweler for a small fee of $45.
