Gold Type
White Gold. Likely alloyed with nickel or palladium and finished with rhodium plating to achieve the cool, silvery luster visible on the rails.
Weight

Description
A sophisticated 18K white gold eternity band featuring a continuous row of channel-set princess-cut diamonds. The ring displays a seamless 'circle of light' design, where each square diamond is secured by shared prongs within protective side rails. This design provides maximum brilliance while maintaining a sleek, modern profile suitable for wedding bands or anniversary stacking.
Key Features
Continuous princess-cut stones, double-rail protective design, 18K purity, and shared-prong architectural stability.
Color & Finish
Bright, cool white with a high-polish finish on the side rails. The rhodium plating appears slightly worn near the edge of the prongs, suggesting a warm undertone in the base alloy.
Hallmarks & Stamps
Likely stamped '750' or '18K' on the inner surface of the band (not visible in image). May contain a maker's mark or diamond carat weight stamp.
Dimensions Estimate
Band width approximately 3.5mm to 4.0mm. Ring size appears to be a standard US 6 or 7. Standard low-profile cross-section.
Gemstones & Inlays
Princess-cut diamonds (approx. 0.10ct - 0.15ct each). Total carat weight (TCW) likely 2.50ct to 3.50ct. Stones appear to be near-colorless (G-H) with VS-SI clarity based on typical commercial fine jewelry standards.
Clasp & Closure
Not applicable (closed circular band).
Chain & Links
Solid 18K gold band with shared-prong and channel crossover construction for stone security.
Craftsmanship Details
Precision-poured investment casting with machine-calibrated stone seats. Manual prong setting follows as evidenced by the uniform pressure on diamond corners.
Authentication Indicators
Characteristic luster of rhodium-plated 18K gold; uniform stone dimensions consistent with calibrated diamond parcels; professional prong symmetry.
Origin & Maker
Commercial luxury maker. Lacks the distinctive artisanal irregularities of hand-forged vintage jewelry, suggesting high-precision casting and machine-assisted stone setting.
Era & Period
Contemporary (2000s-present). The use of princess cuts in a full eternity layout is a modern classic popularized in the late 20th and early 21st century.
Age Estimate
Likely manufactured within the last 10-15 years based on the setting style and prong geometry.
Cultural Significance
Symbolizes everlasting love and commitment, traditionally given to mark significant anniversaries or the birth of a first child.
Condition Notes
Good to Very Good. Slight visible scratches on the metal rails. Prongs appear secure, though cleaning is needed as debris is visible under the stones, which dulls the light refraction.
Value Estimate
$2,500 - $4,500 USD retail depending on stone quality; Melt value approx. $180-$250 based on current spot gold price. Value is primarily in the gemstones and brand/craftsmanship rather than gold weight.
Care & Maintenance
Gentle cleaning with a soft toothbrush and warm soapy water. Eternity bands cannot be resized, so protect from physical impact that could warp the circle and loosen stones. Professional ultrasonic cleaning and rhodium replating every 24 months is recommended.
