Purity
18K RGP (Rolled Gold Plate). This indicates a thin layer of 18-karat gold (75% purity) bonded to a base metal core, typically brass or copper. It is not solid gold.
Gold Type
Yellow gold plating; the alloy likely contains copper and silver for color stability.
Weight
Estimated 2 to 5 grams depending on overall length. The value is not based on gold weight as the precious metal content is minimal.
Description
A delicate 18K yellow gold plated curb chain designed for everyday fashion wear. This piece utilizes a rolled gold plating technique to achieve the look of high-purity luxury at an accessible price point.
Key Features
The 'RGP' stamp is the most critical feature, identifying it as a composite piece rather than solid bullion. The curb links provide a classic, unisex aesthetic.
Color & Finish
High-polish yellow gold finish with visible cooling tones and some surface scratching. The color appears slightly brassy, typical of plated items.
Hallmarks & Stamps
Stamped '18KRGP' on the end-tab connector. 'RGP' explicitly stands for Rolled Gold Plate, a hallmark required by trade regulations to distinguish plating from solid gold.
Dimensions Estimate
Chain width approximately 1.5mm to 2mm; standard petite jewelry sizing.
Gemstones & Inlays
None visible.
Clasp & Closure
Connected to a spring ring or small lobster claw (not fully visible), utilizing a flat stamped end-tab for secure attachment.
Chain & Links
Standard curb link construction with flattened, twisted circular links. Machine-made for uniformity.
Craftsmanship Details
Machine-stamped end-tab with clear but utilitarian lettering. Links are consistent in pitch and alignment, typical of industrial jewelry production.
Authentication Indicators
The 'RGP' stamp is an honest disclosure mark. The relatively lightweight appearance and the slight greenish-yellow hue of the gold are consistent with high-karat plating over a base metal.
Origin & Maker
Unknown mass-market manufacturer; commonly produced in high volume in Italy or China.
Era & Period
Contemporary/Modern (late 20th century to present); a mass-produced fashion jewelry staple.
Age Estimate
Likely manufactured within the last 20-30 years based on font style and construction technique.
Cultural Significance
Represents the democratization of jewelry fashion, allowing for the aesthetic of 18K gold to be worn widely without the high financial barrier of solid gold pieces.
Condition Notes
Good condition with minor surface abrasions. No visible 'brassing' (plating wear-through) on the visible links, though the clasp area shows high-friction contact marks.
Value Estimate
Retail value: $10 - $30. Melt/Scrap value: Negligible ($0), as refineries do not generally process gold-plated items for recovery unless in extreme bulk.
Care & Maintenance
Avoid chemicals, perfumes, and water to prevent the thin gold layer from wearing off. Clean only with a soft, dry cloth; do not use ultrasonic cleaners or abrasive polishes.

Interesting Facts
Rolled Gold Plate is a process where gold is mechanically bonded to base metal using heat and pressure, often lasting longer than simple electroplating but containing very little actual gold value.
