A long bead necklace with a carved centrepiece is a format that works in men's jewellery specifically: the length keeps it clear of a collar, and the obsidian reads as a single line rather than a pattern.
The Pixiu is carved from the same material as the beads rather than cast, so it matches in tone. Obsidian takes a mirror polish because it is glass, which is also why it chips on hard floors — the centrepiece is the part to protect. Clasp is sterling silver, stamped S925.
