This ring is in wonderful condition and shows very light wear and is ready for years of future use. The face measures 14.5mm by 18mm. The inside of the band is stamped 10k SA, and tests as 10 karat gold. The base of the band measures 4mm and the gold has been professionally polished to a bright gold shine.
