Description
A striking, sculptural 18K yellow gold cocktail ring featuring a bold architectural 'ribbed' or tiered motif. The design centers on a large, vibrant yellow gemstone in a professional step-cut facet, seamlessly integrated into the golden structure. This piece commands attention with its substantial mass and reflective geometric surfaces.
Key Features
Horizontal ribbed relief pattern, tiered crown elevation, integrated bezel setting, and high-purity saturated gold color.
Color & Finish
High-polish mirror finish on the internal band and raised ribs; the valleys between the ribs show a soft satin texture. Rich golden-yellow coloration with some surface oxidation in the recessed grooves.
Hallmarks & Stamps
Likely stamped '750' or '18K' on the inner shank. Based on the bold architectural style, it may contain an Italian designer mark (e.g., *1234 AR) or a luxury house logo.
Dimensions Estimate
Width of crown: ~12mm; Band width at base: ~4mm; Ring size: Estimated US 7-8 based on proportion to surface.

Single emerald-cut (step-cut) Citrine or Yellow Quartz, estimated 2.5-4.0 carats, bezel or tension-style flush setting within the tiered head.
Clasp & Closure
Not applicable (Continuous circular ring shank).
Chain & Links
Solid cast construction; D-shape profile on the exterior tapering to a flat, comfortable interior profile.
Craftsmanship Details
Lost-wax casting followed by precision hand-finishing. The symmetry of the ribs indicates high-end manufacturing standards.
Authentication Indicators
Color saturation suggests 18K; the weight distribution appearing 'bottom-heavy' in the image implies solid gold rather than a hollow shell or plating.
Origin & Maker
Likely European origin, specifically Italy (Vicenza or Arezzo districts) known for high-quality ribbed geometric gold work.
Era & Period
Modern / 1980s Retro Revival. The heavy ribbed 'gaspipe' or 'Tubogas' inspired texture is characteristic of 1980s-1990s high-fashion jewelry.
Age Estimate
Circa 1985-1995. The bold proportions and use of large semi-precious step-cut stones align with late 20th-century luxury trends.
Cultural Significance
Represents the 'Power Dressing' era of jewelry where bold, chunky gold was used as a signifier of professional success and female empowerment.
Condition Notes
Very Good. Minor surface micro-scratches consistent with wear; slight accumulation of dust in the grooves. Stone appears free of major chips.
Value Estimate
Melt Value: ~$500-$650; Market Value (Retail): $1,200-$1,800 depending on brand and stone weight.
Care & Maintenance
Clean with warm soapy water and a soft-bristled brush to reach the grooves. Professional ultrasonic cleaning is safe for gold but check citrine for heat sensitivity.
