Approximately 10mm-12mm in height (excluding bail), petite category.

Gemstones & Inlays

Multiple small round-cut stones (totaling approx. 0.10-0.15tcw), likely natural diamonds or high-grade cubic zirconia, set in shared-prong mountings.

Clasp & Closure

Fixed bail attachment with a jump ring suitable for fine chains up to 1.5mm width.

Chain & Links

N/A; standalone pendant. The bail is a solid, polished oval loop.

Craftsmanship Details

Precision-cast components with machine-set prongs. Soldering between the bail and the heart attachment is clean with minimal flash.

Authentication Indicators

The deep, rich yellow color is consistent with 18K gold. Surface luster and sharpness of the prongs suggest high-quality casting rather than cheap plating.

Origin & Maker

Unknown mass-market manufacturer; typical of Italian or Southeast Asian commercial jewelry production hubs.

Era & Period

Contemporary (2000s-present); characterized by computer-aided design (CAD) symmetry and standardized prong settings.

Age Estimate

Cultural Significance

Heart pendants are globally recognized symbols of love, often gifted for anniversaries, Valentine's Day, or as a sentimental heirloom for young women.

Condition Notes

Very Good (Grade: 8/10). Prongs appear intact; high-polish surfaces show micro-scratches from light handling.

Value Estimate

Market value approx. $150-$250 based on current gold spot prices and stone quality. Resale value is largely determined by gold melt weight and a small premium for the diamonds.

Care & Maintenance

Clean with warm soapy water and a soft-bristled brush. Avoid ultrasonic cleaners if stones are fracture-filled. Store in a separate velvet pouch.
