Purity
14K (58.5% Pure Gold). The marking "14K" indicates it is solid 14-karat gold alloy, a standard purity for North American jewelry balancing durability with gold value.
Gold Type
White Gold. The alloy likely includes nickel or palladium to achieve the silvery-white hue, though the visible surface shows a slightly warm undertone suggestive of unplated white gold or worn rhodium.
Weight
2.5 to 5.0 grams. Based on the thickness of the disc and common dimensions for watch case backs or large pendants of this circumference.
Description
This is a functional circular component crafted from solid 14-karat white gold. It features a distinctive brushed sunburst texture that radiates from the center, which serves to hide minor scratches while providing a sophisticated matte aesthetic. The presence of a dedicated serial number suggests it was once part of a high-value item, such as a gold watch or a limited edition medallion, where tracking and authenticity were paramount.
Key Features
Sunburst brushed finish, crisp numerical serialization, and the '14K' purity hallmark. The flat, circular geometry suggests a precision-engineered industrial jewelry use.
Color & Finish
Cool white with a circular-grained / sunburst brushed finish. The surface exhibits heavy concentric and erratic scratches indicating regular contact or tool use, with a matte-to-satin luster.
Hallmarks & Stamps
Stamped '14K' and a six-digit serial number '510021'. The '14K' mark follows US National Stamping Act standards. The serial number is crisp, suggesting machine-stamping.
Dimensions Estimate
Estimated diameter of 25mm to 32mm. The thickness appears to be approximately 0.8mm to 1.0mm, typical for a structural jewelry component.
Gemstones & Inlays
None visible. This is a primary metal component without decorative stone settings or enamel.
Clasp & Closure
Not applicable. This appears to be a fixed component, likely a snap-on or screw-down case back for a timepiece or a large locket insert.
Chain & Links
Not applicable. The item is a solid circular plate without attached links or chain elements.
Craftsmanship Details
Machine-stamped and lathed. The circular graining indicates the piece was finished on a rotating mandrel. Soldering is not visible, suggesting it was die-cut from a sheet of 14K gold.
Authentication Indicators
The depth and consistency of the stamps are typical of genuine gold; plated items rarely feature such deep, crisp serial numbering because it would expose the base metal. The color consistency in the scratches supports it being solid gold.
Origin & Maker
Likely United States origin. The usage of '14K' rather than '585' is highly indicative of the American market. The specific manufacturer remains unidentified sans a visible maker's mark.
Era & Period
Late 20th Century (1970s–1990s). The typeface of the serial number and the style of the '14K' stamp are consistent with mass-produced fine jewelry components of this era.
Age Estimate
Circa 1975–1995. The wear pattern and stamping technique align with a vintage piece approximately 30-50 years old.
Cultural Significance
Represents the mid-to-late 20th-century trend of 'utilitarian luxury,' where everyday functional items like watches were elevated through the use of precious metals and serialized production.
Condition Notes
Good to Fair. The metal exhibits significant surface scratching and micro-abrasions consistent with frequent handling or friction against another surface. The '14K' mark is partially obscured by scratches.
Value Estimate
Primarily Melt Value plus a small premium. Calculated as (Weight x 0.583 x Current Spot Price). As a component, its value is largely tied to its metal content unless reunited with its original assembly.
Care & Maintenance
Clean with a soft brush and warm soapy water. To restore the luster, a professional light buffing can remove the surface scratches. Avoid contact with chlorine, which can cause 'stress corrosion cracking' in white gold alloys.

Interesting Facts
White gold was originally developed as a substitute for platinum. During WWII, the US government banned the use of platinum for non-military purposes, leading to a massive surge in the production of white gold jewelry like this piece.
