Craftsmanship Details
Hand-finished investment casting. The multi-level setting requires precise soldering of the gemstone baskets to the main thick shank.
Authentication Indicators
Saturated yellow color consistent with 18K; deep, clean '18' stamp; high-quality bezel and prong work; substantial heft evident in the casting.
Origin & Maker
Likely European or high-end American manufacture. The styling is reminiscent of Mediterranean designers such as Marina B or Greek goldsmiths.
Era & Period
Late 20th Century (circa 1980s-1990s). The bold, 'chunky' aesthetic with mixed textures and large pearls is characteristic of this jewelry era.
Age Estimate
Circa 1985–1995 based on the use of Mabé pearls and the architectural, tiered gold-work.
Cultural Significance
Represents the 'Power Jewelry' movement of the late 20th century, where jewelry was designed to be bold, visible, and indicate professional and social status.
Condition Notes
Very Good. Visible micro-scratches on gold surface. The pearl shows minor luster softening. Sapphire facets appear crisp with no major chips.
Value Estimate
Estimated $1,800 - $2,500. Value is derived primarily from the 18K gold volume and the decorative appeal of the combined gemstones.
Care & Maintenance
Avoid chemicals; Mabé pearls are sensitive. Clean with a soft damp cloth only. Professional polishing can restore the gold luster but avoid ultrasonic cleaners for the pearl.

Interesting Facts
Mabé pearls, also known as blister pearls, are grown against the inside shell of an oyster rather than within its tissue, allowing for their unique flat-backed shape used in statement jewelry.
