Likely low-karat gold-plated, gold-filled, or costume jewelry base metal alloy, as evidenced by visible verdigris corrosion on the surface. Not solid high-purity gold.
Gold Type
Yellow Gold finish over a non-gold or copper-bearing base metal alloy, suggested by the green oxidation spot.
Weight
Estimated lightweight jewelry piece, approximately 4 to 8 grams based on visual shank thickness and size.
Description
This is a bold, geometric band ring featuring a distinct grid-like or stepped carved pattern across its upper face. The piece exhibits a warm yellow hue with a slightly worn satin finish. A prominent green oxidation spot on the side reveals that the ring is constructed from a base metal alloy with a gold-tone surface plating rather than solid gold.
Key Features
Distinctive raised geometric grid carving on the top face, chunky profile, and visible verdigris oxidation indicating base metal content.
Color & Finish
Warm yellow gold tone with a satin to matte surface finish. A notable green copper-carbonate corrosion spot (verdigris) is present on the side face.
Hallmarks & Stamps
No clear hallmarks or purity stamps are visible in the provided image.
Dimensions Estimate
Standard men's or heavy women's ring size, roughly US size 8 to 10, with a bold band width of approximately 6mm to 8mm at the top face.
Gemstones & Inlays
No gemstones or inlays. Features carved or cast geometric grid-like grooves across the top face.
Clasp & Closure
Solid continuous band ring; no clasp or closure mechanism applicable.
Chain & Links
Not applicable; solid band construction with a flat inner profile and a stepped, grooved exterior profile.
Craftsmanship Details
Likely produced via industrial casting or stamping methods, followed by surface grooving and electroplated gold-tone finishing.
Authentication Indicators
The presence of green verdigris corrosion is a definitive indicator of a copper-bearing base metal (such as brass or bronze) with failing gold-tone plating, proving the item is not solid gold.
Origin & Maker
Unknown manufacturer or country of origin, typical of mass-market or costume jewelry production.
Era & Period
Mid-20th Century to Late 20th Century modern or novelty costume design, reminiscent of 1970s-1980s chunky fashion jewelry.
Age Estimate
Likely produced within the last 30 to 50 years (circa 1970s-1990s), inferred from styling and wear patterns.
Cultural Significance
Bold geometric rings gained immense popularity during various 20th-century fashion revivals, offering the dramatic look of heavy gold bullion or modernist art without the high cost of precious metals.
Condition Notes
Fair condition with noticeable surface wear, softening of edges, and a distinct green corrosion patch (verdigris) on the shank indicating plating loss and base metal exposure.
Value Estimate
Melt value is zero due to the lack of precious metal content. Secondary market value is strictly decorative or sentimental, typically under 10 to 20 USD as a vintage fashion accessory.
Care & Maintenance
Clean gently with a soft, dry microfiber cloth. Avoid water, harsh chemical dips, and abrasive polishing, as these will strip away the remaining gold plating and accelerate base metal corrosion.

Interesting Facts
Verdigris is a green patina that forms naturally when copper, brass, or bronze is exposed to moisture and air, frequently found on vintage costume jewelry when the outer gold or rhodium plating wears away.
