24Kt Gold PVD Titanium 3-Cluster Prong Set Gem Side Facing Hinged Segment Clicker. ? The design uses precision prong settings to secure a square princess gemstone between two matching triangle CZs. Because the stones face outward along the curve of the hoop, they maintain visibility from straight on—offering a bright, refined aesthetic. Made from implant-grade titanium Ti-6AL-4V-ELI ASTM F136 and coated with 24K gold through the Physical Vapor Deposition (PVD) process. The PVD process fuses pure gold to the titanium at the atomic level, creating a nickel-free, chemically stable surface that won’t peel, tarnish, or react with the skin. It’s safe for long-term wear and ideal for healed piercings.
