Weight

Description
A sophisticated mid-century gold disc pendant featuring a striking radial engine-turned pattern that creates a shimmering light effect. The center remains polished, offering a space for custom engraving of initials or a date.
Key Features
Concentric circle guilloché pattern, substantial flat-disc construction, and a clear polished central focal point.
Color & Finish
Rich warm yellow with a dual-texture finish featuring a concentric engine-turned (guilloché) outer ring and a high-polish mirror center.
Hallmarks & Stamps
None visible on the face; likely located on the reverse side or the bail (jump ring) as a '14K' or '585' stamp.
Dimensions Estimate
Approximately 25mm to 30mm in diameter (roughly the size of a U.S. Half Dollar), standard for large statement pendants.
Gemstones & Inlays
None; the piece features pure metallic decoration through mechanical engraving.
Clasp & Closure
Features a simple circular bail (jump ring) soldered to the top for suspension from a chain.
Chain & Links
Not attached; however, the bail is designed to accommodate a medium-gauge cable or curb chain.
Craftsmanship Details
Precision-machined engraving (guilloché) shows high uniformity; the bail is neatly soldered with minimal visible seam, indicating professional workshop quality.
Authentication Indicators
Color uniformity is consistent with solid gold alloy; absence of base metal 'brassing' at high points suggests quality metal content.
Origin & Maker
Likely North American or European manufacture; the engine-turned style was a hallmark of boutique manufacturers from that era.
Era & Period
Mid-Century Modern (circa 1950s-1970s), characterized by bold geometric shapes and machined textures.
Age Estimate
Likely produced between 1960 and 1980, based on the thickness of the disc and the specific radial engraving pattern.
Cultural Significance
Large gold discs were iconic fashion staples in the 1970s, often worn on long chains to symbolize wealth and personal identity.
Condition Notes
Very Good; presents minor surface abrasions and light patina consistent with age. Texture remains sharp and well-defined.
Value Estimate
Primarily valued by weight (melt value) plus a 20-40% premium for vintage design; estimated market value $350-$600 depending on final weight.
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid ultrasonic cleaners if the metal is hollow; professional buffing can restore the center polish.
