Purity
Indeterminate; visual suggests potential gold plating or low-karat alloy (9K-14K) typical for structural findings
Gold Type
Yellow Gold Alloy (likely containing copper and silver)
Weight
3-5 grams based on estimated dimensions and density
Description
A machined yellow gold-toned cylindrical component featuring a longitudinal split design. The piece appears to be a precision-engineered finding or a mechanical fastener designed to use tension for security within a larger assembly, such as a heavy bracelet hinge or watch link pin.
Key Features
Cylindrical body with a deep tension slot and beveled tip for easy insertion.
Color & Finish
Dull yellow with a satin, machined surface finish; visible horizontal tooling marks
Hallmarks & Stamps
No hallmarks visible in the current image; typical of internal components or unfinished findings
Dimensions Estimate
Approx. 20mm length / 3-4mm diameter
Gemstones & Inlays
None
Clasp & Closure
Split-pin tension mechanism for friction-fit insertion
Chain & Links
Not applicable
Craftsmanship Details
Precision lathe-turned or machined component with standardized tolerances.
Authentication Indicators
The color is consistent with gold, but the visible grain and tool marks suggest it may be a base metal plated with gold or a harder, low-purity alloy meant for mechanical durability.
Origin & Maker
Likely mass-manufactured technical finding; origin unknown
Era & Period
Modern / Industrial (late 20th century to present)
Age Estimate
Contemporary (1990s-present)
Cultural Significance
Represents the intersection of luxury materials and industrial engineering.
Condition Notes
Good; shows minor surface abrasions and machining marks consistent with industrial production.
Value Estimate
If solid 14K, approx. $150-$200 USD melt value; if plated, nominal value ($1-$5 USD).
Care & Maintenance
Keep free from grit; do not over-flex the split section to avoid metal fatigue or snapping.
