Antique Victorian 15k yellow gold bloodstone ring featuring a substantial oval bloodstone cabochon with deep green color and natural red inclusions. The stone measures approximately 19 x 15 mm, while the ring top measures about 21 x 16 mm for a bold presence. The ring weighs 10.6 grams and is a size 7.75. There is no visible hallmark, though the gold has been professionally tested and confirmed as 15k. It is in good antique condition with age-related wear consistent with its history. A handsome Victorian piece with unique character and strong collector appeal.
