Vintage 14k Gold Old Mine Cut Diamond Gypsy Set Ring

This is a fine vintage or antique 14k yellow gold ring featuring a prominent round old-style cut diamond, likely an Old Mine or Old European cut, flush-mounted in a buttercup-style gypsy setting. The ring is a size 9 and weighs 4.3 grams. The central diamond measures approximately 5mm in diameter, suggesting a weight of approximately 0.50 to 0.60 carats, though the depth noted in the description implies a significant pavilion depth characteristic of antique cuts. The metal construction consists of a solid 14k yellow gold shank that tapers from a wide, rounded head down to a narrower base. The design features a scalloped, petal-like decorative engraving around the diamond, giving it a floral appearance within the metal. The condition shows significant surface wear, including fine scratches (micropitting) and a soft patina consistent with age and regular use. The metal appears dense and well-crafted, typical of Late Victorian or Edwardian era men's or unisex signet-style rings. There are no visible maker's marks or stamps from this angle, but the gold has a deep, rich yellow hue characteristic of high-quality vintage alloys.
