Purity
18K (750 fineness), approximately 75% pure gold content mixed with copper and silver alloys.
Gold Type
Yellow gold with a rich, saturated hue typical of high-karat European or Middle Eastern alloys.
Weight
Estimated 8 to 12 grams; appears to be an urban mid-weight solid construction rather than hollow.
Description
A bold, masculine 18K yellow gold signet ring featuring a distinctive tiered geometric face. The design employs a 'step-up' architectural motif, leading to a flat rectangular top. Its seamless construction and warm luster make it a classic statement piece that balances vintage weight with modern lines.
Key Features
Multi-leveled rectangular face, broad tapered shoulders, and a high-karat 'butter' yellow color saturation.
Color & Finish
Deep warm yellow with a high-polish finish; exhibits micro-scratches and a soft patina indicative of regular wear.
Hallmarks & Stamps
Not clearly visible in the image, but likely located on the internal inner band (shank). Expected stamps: '750' or a small rectangular maker plaque.
Dimensions Estimate
Estimated US ring size 9-11; face width approximately 12-14mm; shank thickness approx 1.5mm.
Gemstones & Inlays
None; the design relies on architectural metalwork and a flat gold table without stones.
Clasp & Closure
Not applicable (solid continuous band circumference).
Chain & Links
D-shape (domed) exterior profile with a flat interior comfort-edge; tapered shoulders meeting a rectangular face.
Craftsmanship Details
Cast gold construction with hand-finished polishing; precise geometric angles indicate a high-quality mold and careful finishing work.
Authentication Indicators
The color saturation is consistent with 18K gold; lack of 'brassing' or plating wear at high-friction points suggests solid gold throughout.
Origin & Maker
Likely of Italian or Mediterranean origin given the 18K purity and style of the casting and finish.
Era & Period
Late 20th Century Modern / Contemporary (likely 1980s-2000s) reflecting Brutalist or Geometric influences.
Age Estimate
Circa 1985–2010; the manufacturing technique suggests centrifugal casting common in mid-to-late 20th-century jewelry.
Cultural Significance
Signifies status and heritage; in many European cultures, 18K is the minimum standard for fine investment-grade jewelry.
Condition Notes
Very Good; light surface abrasions are present, but the structural integrity of the shank is excellent with no signs of thinning or resizing.
Value Estimate
Estimated $650 - $950 USD, based primarily on gold melt value plus a 20-30% premium for design and craftsmanship.
Care & Maintenance
Clean with warm soapy water and a soft brush; professional buffing can restore the mirror finish, but will remove a microscopic amount of gold weight.
