Weight
2.5 - 3.5 grams; based on the slender shank and cast bypass setting, this is a standard lightweight commercial production.
Description
An elegant yellow gold fashion ring featuring a bypass design that gracefully curves around a central oval sapphire. The deep blue gemstone is accented by two small diamonds set in white gold or rhodium-plated accents to enhance their sparkle. The sculptural gold waves on the shoulders provide a sense of movement and classic feminine styling.
Key Features
Bypass (crossover) shank design, contrasting white metal diamond accents, and a distinct 'swooping' gold ribbon motif on the shoulders.
Color & Finish
Pale yellow gold with a high-polish finish; the surface shows minor pocket wear and a slight patina consistent with pre-owned jewelry.
Hallmarks & Stamps
Likely stamped '10K' or '417' on the inner shank, potentially accompanied by a small maker's mark (pictograph or initials) representative of a mass-market manufacturer.
Dimensions Estimate
Estimated US Ring Size 6.5 to 7.5; shank width approx 1.5mm tapering to 6mm at the decorative head.
Gemstones & Inlays
One oval-cut dark blue sapphire (likely commercial grade/treated) approximately 0.40ct, flanked by two small round-cut diamond accents (estimated I-J color, I1 clarity) in white metal illusion prongs.
Clasp & Closure
Not applicable (solid ring shank).
Chain & Links
The ring features a bypass-style bypass shank with sculptural 'swoop' or wave-like details leading to the central setting.
Craftsmanship Details
Lost-wax casting method; the settings are integrated into the mold with stones hand-set later. Solder points are hidden within the bypass junctions.
Authentication Indicators
Color consistency is typical for 10K yellow gold; no evidence of plating wear/peeling (which would suggest costume jewelry). Hallmarks should be present on the interior lower shank.
Origin & Maker
Likely North American (USA or Canada) mass-market jeweler; items of this style were high-volume productions for department store jewelry counters.
Era & Period
Modern/Contemporary Era; specifically late 20th century (circa 1980s or 1990s) based on the bypass design and the use of illusion settings for small diamonds.
Age Estimate
Approximately 25-40 years old (circa 1985-1995).
Cultural Significance
Symbolizes mid-to-late 20th-century attainable luxury, representing the shift toward gold jewelry as everyday fashion accessories rather than just formal heirlooms.
Condition Notes
Very Good; minor surface scratches consistent with use. The prongs appear intact, though the central sapphire shows minor facet-edge wear. No signs of resizing or structural thinning.
Value Estimate
$150 - $250 Retail; the value is primarily in the gold bullion weight (melt value approx. $80-$110) plus a modest collector premium for the gemstones and wearable condition.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid ultrasonic cleaners if the sapphire has reach-surface fissures. Store separately to prevent the harder sapphire from scratching other gold pieces.
Similar Items
Commonly compared to 'S-curve' rings or traditional 'Three-Stone' anniversary bands, though the bypass silhouette offers a more fluid, asymmetrical aesthetic.
