Interior band stamps including French eagle's head (standard mark for 18k gold), Cartier signature (script/serif), '750' or '18K' purity mark, and serial number.
Construction Details
Cast and hand-finished. Three independent circular bands are permanently interlocked before closing, allowing them to roll over each other smoothly.
Functional Features
'Rolling' mechanism where bands glide over each other to fit onto the finger. Permanent interlocking design prevents loss of individual bands.
Handle & Grip Details
N/A (Jewelry item). Inside band is smooth and domed (comfort fit) for ease of wear.
Craftsmanship Details
Superior finishing with no visible solder joints on the bands; perfectly balanced weight so the bands roll without catching.
Authentication Indicators
Deep, clear stamping of the Cartier logo and serial number; French assay marks (Eagle head) often located on the outside or inside rim of the bands.
Origin & Manufacturing
France (likely Paris), using traditional high-jewelry bench techniques and modern precision casting.

Modern/Contemporary production of a 1920s Art Deco classic. High Design period context.
Age Estimate
Likely late 20th century to contemporary (post-1980s based on stamp styles and clarity).
Cultural Significance
Symbolizes the three stages of a relationship. It moved jewelry away from ornate gemstone-heavy designs toward sculptural, meaningful metalwork.
Condition Notes
Very good overall; minor surface micro-scratches consistent with wear; high-polish remains intact. Polishing may be required to restore mirror finish.
Value Estimate
$800 - $3,500 USD depending on size (small, medium, or large model) and current gold market spot prices.
Care & Maintenance
Clean with warm soapy water and a soft brush. Keep away from chlorine. Professional polishing recommended every few years to remove scratches.
