The Science of "Stay-On" Jewellery: What is PVD?
Blog post description.
You’ve seen the "waterproof" claims, but if you’ve been burned by high-street jewellery before, you’re probably sceptical. We’ve all been there—buying a "gold" necklace only for it to turn your skin green or lose its lustre within a month.
At House of Saya, we do things differently. The secret to our "never take it off" promise isn't magic—it’s PVD Vacuum Coating.
What is PVD, anyway?
PVD stands for Physical Vapor Deposition. While traditional gold plating involves dipping metal into a liquid (which can easily flake or peel), PVD is a high-tech vacuum process.
The gold is bonded to our medical-grade stainless steel at a molecular level. This creates a finish that is significantly harder and more resilient than the industry standard.
Why it’s a Game Changer for You
Because PVD is so tough, it changes how you live in your jewellery.
It’s Sweat-Proof: Go ahead, finish that HIIT class. The salt in your sweat won't corrode the finish.
It’s 100% Waterproof: Forget removing your rings every time you wash your hands or jump in the shower.
It’s Hypoallergenic: No itching, no redness, and absolutely no green skin.
