Overall Condition: Very Good
Condition Notes: This elegant choker necklace features elongated black onyx links ranging from approximately 29.80 x 9.95 x 6.20 mm to 35.35 x 10.15 x 6.30 mm, each accented with seed pearls set in gold, and rose-cut diamonds set in platinum. The rose-cut diamonds measure approximately 1.50 mm in diameter, adding a subtle shimmer against the contrast of the polished onyx. Minor chips and abrasions are visible on several onyx links and several diamonds are chipped, consistent with age and wear, though overall structural integrity remains intact. The tongue clasp is marked with a French eagle’s head assay mark for 18k gold, alongside a maker’s mark bearing "MF" in a diamond-shaped outline. The clasp functions well and secures tightly.
