Akoya Cultured Pearl Necklace Solid 835 Silver Vintage Designer Clasp by JKa An elegant, high quality vintage Japanese Akoya cultured pearl necklace, highlighted by a beautiful and highly collectible designer clasp from the renowned German luxury jewelry manufacturer J. Köhle (JKa) from Pforzheim (famous for high end patented clasps since 1919). The necklace has been fully measured and verified with precision instruments, as documented in the photo gallery. Pearls Type: Genuine saltwater Akoya cultured pearls. Pearl Diameter: Large and highly desirable 8.0 mm (precisely verified with a caliper). Akoya pearls of this size are rare and highly valued for their perfectly round, spherical shape. Luster & Color: Beautiful, high quality luster with a sharp light reflection. Elegant cream/champagne body color with warm, rich overtones. Verified Authenticity: Under extreme macro magnification (foto in gallery Micro), the pearl surface clearly reveals the authentic, organic concentric growth lines and natural micro textures of genuine nacre layers. There is absolutely no synthetic coating or imitation glass base. Total Length: 60 cm (Matinee length). Measures exactly 30 cm when doubled/folded next to the measuring tape. Total Weight: Heavy and substantial 53.47 grams (verified on a precision digital scale), proving the high density of the natural nacre layers. Clasp Manufacturer: JKa (J. Köhle, Pforzheim, Germany). Clasp Material: Solid 835 Silver (fully hallmarked with "835" and the famous "JKa" maker's mark). Clasp Design: Gorgeous vintage floral/flower motif set with sparkling accent paste stones and a central accent pearl. The clasp mechanism works perfectly and securely. Craftsmanship: Traditionally hand knotted on a strong silk thread with security knots between each individual pearl to protect them from friction. The impressive total weight for a 60 cm necklace further confirms the high density and thickness of the natural nacre layers grown inside the oyster. Condition: Excellent vintage condition with minimal, minor signs of age appropriate wear. The pearls retain a wonderful mirror like shine, and all accent stones on the clasp are complete and intact. A timeless, sophisticated addition to any fine jewelry collection, perfect for special occasions or as an investment piece. Shipping: Professionally packed and shipped immediately with an international tracking and secured number.
