Type
Jewelry Finding (Box Clasp Component)
Purity
14K or 585, which indicates approximately 58.5% pure gold alloyed with secondary metals for strength.
Gold Type
Yellow Gold (Classic alloy likely featuring copper and silver to maintain a rich, warm tone for utilitarian components).
Weight
0.1 to 0.3 grams. This is a very lightweight, thin-gauge structural component rather than a solid piece of jewelry.
Description
A single yellow gold box clasp tongue, designed as the male portion of a locking mechanism. It features a rectangular cutout for the spring-loaded release button and a folded tab for tension.
Key Features
Folded tension spring design and precision-cut rectangular catch-hole meant to interface with a spring-loaded box.
Color & Finish
Medium yellow hue with a satin to matte worn finish. The surface lacks high polish due to its functional role inside a clasp.
Hallmarks & Stamps
None visible in the image. Such small internal components are rarely stamped; the hallmark is usually on the external closure or the final link of the chain.
Dimensions Estimate
Approximately 8mm to 12mm in length; 3mm to 5mm in width. It appears to be a standard size for a bracelet or light necklace clasp.
Gemstones & Inlays
None. This is a purely functional mechanical finding.
Clasp & Closure
This is the 'tongue' or 'insert' portion of a box clasp (also known as a tongue-and-groove or hidden clasp).
Chain & Links
Not applicable; this is a single mechanical component designed to be soldered or attached to a link or chain.
Craftsmanship Details
Machine-stamped from a gold sheet and folded. The construction emphasizes functional utility and standard tolerances over artistic hand-finishing.
Authentication Indicators
The color consistency and lack of 'brassing' (base metal showing through) suggest solid karat gold. However, without a stamp, it requires XRF or acid testing.
Origin & Maker
Likely a generic industrial jewelry supply manufacturer from Italy or the United States.
Era & Period
Contemporary/Modern (late 20th century to present). The stamped metal construction is typical of mass-produced jewelry findings.
Age Estimate
Likely manufactured within the last 20-30 years based on the stamping technique and clean industrial lines.
Cultural Significance
Represents the industrialization of jewelry making, where replaceable precision parts allow for the maintenance of luxury heirlooms.
Condition Notes
Fair. The piece appears slightly flattened or bent, which may affect its tension and ability to lock securely. Surface shows micro-scratches from friction.
Value Estimate
Primarily melt value (approx. $5 - $15 USD depending on spot price) or utility value as a repair part (approx. $20 - $40 at a jeweler).
Care & Maintenance
Clean with mild detergent and a soft brush. Caution: Do not over-bend the gold tab, as constant manipulation will work-harden and snap the gold.

Interesting Facts
Box clasps are often used on tennis bracelets and high-end chains because they provide a 'seamless' look where the clasp is hidden within the design.
