Construction Details
Lost-wax cast construction with hand-set stones. Prongs are integrated into the head casting and tightened over the gemstones.
Functional Features
Tapered shank for comfort; elevated prong setting to allow light to penetrate the gemstones from the sides and bottom.
Handle & Grip Details
Not applicable (Jewelry item). The shank (band) serves as the primary contact point.
Craftsmanship Details
Quality commercial casting. Solder seams at the head-to-shank junction are well-blended. Stone settings are symmetrical, indicating professional-grade manufacturing.
Authentication Indicators
The 'AAJ' and '10K' stamps are crisp and properly struck. The wear patterns on the band are consistent with gold alloy rather than plated base metal. No greening or plating loss is visible.
Origin & Manufacturing
United States, likely New York City. Produced in a high-volume professional jewelry workshop using precision casting techniques.
Era & Period
Modern / Late 20th Century (Post-1970). The style and stamping font are consistent with 1980s or 1990s commercial fine jewelry.
Age Estimate
Circa 1980-1995. The 'AAJ' mark was most active in the wholesale market during this period.
Cultural Significance
Represents the 'democratization' of fine jewelry in the late 20th century, where 10K gold made precious gemstone jewelry accessible to the middle class for anniversaries and birthdays.
Condition Notes
Very Good. Minimal thinning of the shank. Prongs appear intact. Light surface micro-scratches on the gold surface consistent with gentle wear. No visible chips in the central stone.
Value Estimate
$100 - $225 USD. Primary value is based on the 10K gold scrap weight plus a premium for the sapphire and retail appeal.
Care & Maintenance
Clean with warm water, mild dish soap, and a soft-bristled toothbrush. Avoid harsh chemicals or ultrasonic cleaners if the stones have significant inclusions. Store separately to prevent diamonds from scratching the gold of other pieces.
