The Invictus 24KT Gold PVD Titanium "Lustre Cluster" Gem Threadless Top radiates sophistication and balanced brilliance. Pin Size: 0.45mm x 4.7mm. Fits and bar or base in the Invictus threadless body jewellery line Featuring a stunning trio of baguette, round, and princess-cut cubic zirconia, this top creates a dynamic play of light and form. Each gem is prong-set to maximize sparkle and depth, while the combination of shapes adds harmony and visual dimension. The result — a refined, modern cluster that glows with effortless elegance. 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.
