Description:
A domed, oval-cabochon signet ring of modernist form with broad rounded shoulders and a polished yellow-metal shank. The bezel holds a dark blue cabochon (likely sapphire, lapis, blue chalcedony, or glass). Hallmarks are not visible in the photo, so the metal could be solid gold (14k–18k) or gold-plated base metal.
Curator Questions
Curated by Jade
Assessment:
This appears to be a contemporary signet ring with a blue cabochon in a bold, modernist mount. Without visible hallmarks or metal/stone testing, it should be treated as an attractive fashion piece first; professional testing could significantly increase value if the metal is solid gold and the stone is natural. A word about fakes.. costume jewelry and gold-plated rings are extremely common in this category, and glass cabochons are often passed off as sapphire or chalcedony—proceed only with hallmark inspection and acid/XRF testing, and, for the stone, gemological verification.

Provenance:
No provenance provided.
Condition:
Very good (light surface wear; stone appears intact; not officially graded or metal-tested)
Identification Score: 70%
Confident it is a modern cabochon signet ring based on the chunky, rounded mount and oval bezel with a domed blue stone; exact metal and gem type cannot be confirmed from the single image.
Authenticity Score: 30%
No hallmarks or assay marks visible; metal and gemstone untested; category has high prevalence of gold-plated settings and glass cabochons, so authenticity as solid gold with natural gem is uncertain pending testing.
Image Memory Note
Single image shows a yellow-metal signet-style ring on a light-colored desk. The ring has a broad, rounded, slightly tapered shank and a central oval bezel set with a dark blue domed cabochon. The stone appears smooth and evenly colored, with a glossy surface; no visible inclusions from this distance. The metal presents as bright yellow with a polished finish; no engraving or ornament on shoulders. No hallmarks or stamps are visible inside the shank due to angle and resolution. Condition appears clean with minor surface wear; no obvious dents, chips, or cracks. The scene includes part of a computer keyboard in the upper left, implying modern context and scale. No additional components or inscriptions are visible.
