Type
Pendant / Decorative Component
Purity
Likely 10K (41.7%) or 14K (58.5%) based on the deep copper hue; requires testing as surface oxidation suggests a high alloy content.
Gold Type
Rose Gold / Pink Gold (High copper-to-gold alloy ratio).
Weight
3.5 to 5.0 grams (Estimated based on plate thickness and dimensions).
Description
A flat-profile, geometric rose gold pendant featuring two interlocking 'U' or 'L' shapes. The piece has a distinct industrial, architectural feel common in the third quarter of the 20th century. It serves as a study in negative space and sharp angles.
Key Features
Interlocking maze-like geometric silhouette; deep pink color; flat sheet construction.
Color & Finish
Deep rose/copper tone with a dull satin finish; exhibits significant surface scratches, tarnish, and a notable grayish patina near the center solder joint.
Hallmarks & Stamps
No hallmarks are visible on the front or the flat surfaces shown. Testing is required to verify purity.
Dimensions Estimate
Approximately 35mm x 20mm; Flat cut geometric profile.
Gemstones & Inlays
None; purely metallic construction.
Clasp & Closure
Missing; the central blob suggests a jump ring or bail was previously soldered here and has since snapped off.
Chain & Links
N/A; item is a standalone flat plate cutout.
Craftsmanship Details
Machine-stamped from a gold sheet; the edges appear relatively sharp but unrefined. The current state is marred by poor secondary soldering at the center.
Authentication Indicators
The color is consistent with low-karat rose gold, but the dullness and oxidation suggest it could be gold-filled or brass with a gold wash. Red flag: The gray/silver color of the solder at the center suggests a non-gold repair or lead-based solder used by an amateur.
Origin & Maker
Unknown; appears to be a mass-produced stamped or machine-cut piece, likely of commercial origin rather than a high-end designer.
Era & Period
Modernist / Retro (circa 1960s-1970s). The interlocking geometric design is characteristic of mid-century abstract jewelry.
Age Estimate
Circa 1970 - 1985 based on geometric motif and the visible oxidation of the alloy.
Cultural Significance
Represents the shift toward minimalist, non-traditional jewelry designs that favored shape and form over precious gemstones during the mid-to-late 20th century.
Condition Notes
Poor to Fair. Significant surface abrasions; central structural failure where a bail was likely attached; messy solder residue visible at the center juncture.
Value Estimate
Primarily melt value (scrap) due to damage; approximately $120-$180 USD assuming 14K solid gold, or negligible value ($5) if gold-plated brass.
Care & Maintenance
Requires a professional polishing cloth and a mild detergent soak. Avoid ultrasonic cleaners if the solder is lead-based. A professional jeweler should remove the old solder and install a proper gold bail.

Interesting Facts
Rose gold was popularized in 19th-century Russia (often called 'Russian Gold'), but saw a massive resurgence in the 1970s as a warmer alternative to yellow gold.
