Type
Ring (Wide Flat Band)
Purity
Indeterminate; visual characteristics suggest potential 9K (37.5%) or possible brass alloy. Brassy undertones and horizontal striations are atypical for high-purity gold.
Gold Type
Brass-toned Yellow Gold or Base Metal Alloy with high copper content.
Weight
10-15 grams depending on internal diameter; the piece appears thick-walled and bulky.
Description
A heavy, wide-profile metallic band featuring a flat exterior surface and vertical side walls. The item exhibits a greenish-yellow hue rather than the rich luster of high-karat gold, and the surface displays prominent horizontal grinding or machining lines consistent with raw industrial finishing.
Key Features
Extremely wide band width, flat exterior profile, and distinctive horizontal surface texture.
Color & Finish
Dull olive-yellow with visible horizontal machining marks and a matte, unpolished surface.
Hallmarks & Stamps
No visible hallmarks or stamps in the provided image. Interior markings are required for authentication.
Dimensions Estimate
Approximately 10mm to 12mm in width; thick profile suggesting a heavy comfort-fit or flat style.
Gemstones & Inlays
None visible; solid metal construction.
Clasp & Closure
Not applicable (solid continuous band).
Chain & Links
Not applicable; solid band construction with flat, vertical side walls.
Craftsmanship Details
Basic cast or machined construction; the presence of visible tool marks suggests a lack of final high-polish finishing.
Authentication Indicators
Red Flags: The color appears 'brassy' rather than 'golden'. The visible oxidation and rough surface grain are common in brass or gold-plated base metals rather than solid gold.
Origin & Maker
Unknown; appearance suggests a workshop-made or mass-produced industrial component or hardware-inspired fashion ring.
Era & Period
Modern Industrial (late 20th century to contemporary).
Age Estimate
Likely produced within the last 20-30 years based on machining marks.
Cultural Significance
Represents the minimalist, industrial aesthetic often associated with brutalist jewelry movements.
Condition Notes
Poor to Fair; significant surface scratching, pitting, and evidence of oxidation or base-metal exposure (tarnishing).
Value Estimate
Primarily decorative or scrap value. If confirmed as brass, value is negligible ($1-$5). If 9K gold, value is based on weight-to-melt ratio.
Care & Maintenance
If gold: use a soft cloth and mild soap. If brass: use a specialized metal cleaner to remove the heavy oxidation visible on the surface.

Interesting Facts
In jewelry history, wide bands were often used as signet bases or cigar bands, but the lack of a smooth polish here is more common in 'steampunk' or industrial-themed accessories.
