The Invictus 24KT Gold PVD Titanium "Harmony Cluster" Gem Threadless Top brings perfect balance and brilliance to fine body jewelry. Crafted from Implant-Grade Titanium and coated in a radiant 24KT gold PVD finish, this piece combines strength, biocompatibility, and timeless elegance. Pin Size: 0.45mm x 4.7mm. Fits any bar or base in the Invictus threadless body jewellery line. 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. The 24K Gold PVD layer is highly resistant to scratches, fading, and discoloration. Because it bonds directly with the titanium surface, it maintains its radiant, golden shine and smooth feel through continuous wear.
