Blue Coral Barrel Bead Necklace with Magnetic Gold Clasp

This is a single-strand necklace featuring natural blue coral (Heliopora coerulea) beads fashioned into a barrel or cylindrical shape. The beads exhibit a mottled aesthetic with shades ranging from dusty denim blue to muted grey, interspersed with white skeletal calcite structural patterns characteristic of genuine sponge or organ-pipe coral. The beads are approximately 4-6mm in diameter and are strung on a flexible wire cable. The necklace is secured by a distinctive barrel-shaped magnetic clasp in yellow gold tones, which appears to be either gold-plated or gold-filled based on the high luster. The construction shows a consistent alignment of the porous bead structure, indicating a mid-range level of craftsmanship typical of late 20th-century or early 21st-century fashion jewelry. The condition is fair to good, though some beads shows slight edge wear and surface pitting natural to the specimen, and there is visible gapping near the clasp where the internal wire cable is exposed, suggesting it may require restringing for security. No hallmarks are immediately visible on the clasp in this view.
