Purity
18K (750 fineness), representing 75% pure gold and 25% alloy metals, commonly palladium or nickel for strength and color.
Gold Type
White Gold, likely rhodium-plated to achieve the bright silver-white reflective finish.
Weight
Estimated 4.5 to 6.0 grams total weight, depending on band thickness and stone density.
Description
An elegant and regal cocktail ring featuring a prominent oval dark blue sapphire. The stone is elevated by a tiered double-layer diamond halo, creating a voluminous 'bullseye' effect that maximizes brilliance and finger coverage. The high-polish white gold shank provides a sleek, modern foundation for the ornate gemstone cluster.
Key Features
Double halo setting style, split-prong or micro-prong diamond accents, and a classic four-prong primary setting for the sapphire.
Color & Finish
Cool bright white with a high-polished mirror finish. Minor surface wear suggests the underlying warm white-gold alloy may eventually show through the rhodium plating.
Hallmarks & Stamps
Likely stamped '750' or '18K' on the inner shank. May include a jeweler's logo or total carat weight (CTW) stamps for the accent diamonds.
Dimensions Estimate
Oval head approximately 12mm x 14mm; shank width ~2mm; estimated ring size 6.5 US.
Gemstones & Inlays
Center oval-cut natural blue sapphire (estimated 1.5 - 2.0 carats) featuring a deep navy hue with visible silk inclusions. Surrounded by a double halo of small round brilliant-cut diamonds (approx. 0.40 - 0.60 CTW).
Clasp & Closure
Not applicable; solid continuous band construction.
Chain & Links
Standard tapered shank with a smooth interior profile for comfort fit.
Craftsmanship Details
Precision lost-wax casting with hand-set micro-diamonds. Symmetrical halo alignment indicates quality mass-production or high-end boutique benchwork.
Authentication Indicators
Color consistency across the white gold, crispness of the prong settings, and the refractive behavior of the accent diamonds. Natural inclusions in the sapphire suggest authenticity over glass/synthetic alternatives.
Origin & Maker
Likely commercial fine jewelry production, possibly of Italian or Southeast Asian manufacture (common for high-karat sapphire settings).
Era & Period
Contemporary (post-2010), designed in a 'Princess Diana' inspired Neo-Classical aesthetic.
Age Estimate
Produced within the last 5-15 years, based on the precision of the micro-pave setting technique.
Cultural Significance
Sapphires have historically symbolized nobility, truth, and sincerity, traditionally used by royalty to protect against envy and harm.
Condition Notes
Very Good. The sapphire shows slight surface abrasions consistent with wear. Prongs appear secure, though the rhodium plating is slightly dulling on the underside of the band.
Value Estimate
Retail Replacement: $1,800 - $3,500; Secondary Market/Resale: $700 - $1,200; Scrap Melt Value: ~$200 - $280. Total value is predominantly in the gemstones and craftsmanship rather than gold weight.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid ultrasonic cleaners if the sapphire has significant fractures. Periodic professional rhodium replating every 2-3 years will maintain the bright white finish.
