Japanese Triple-Strand Akoya Pearl Necklace with Onyx and Gold Clasp

This elegant vintage necklace features three uniform strands of what appear to be Japanese Akoya cultured pearls, known for their high luster and signature cream-pink overtones. The round pearls measure approximately 6-7mm each, displaying a smooth surface with minimal observable spotting. The centerpiece of the necklace is a decorative oval-shaped clasp, which functions as both a fastener and a focal pendant. This clasp features a polished black cabochon, likely onyx, set within a textured yellow gold-tone floral or filigree-style frame. The construction utilizes high-quality silk threading with visible knotting between each pearl, a hallmark of fine craftsmanship that protects the nacre from friction and secures the necklace should a strand break. The style and materials point toward a mid-to-late 20th-century aesthetic, common in Japanese high-end accessory exports. The condition appears excellent with well-maintained luster, though the metal components show typical light surface oxidation consistent with age. There is no visible sign of pearl peeling or significant nacre loss, indicating careful storage and limited wear.
