How waterproof jewelry is made – the process from the inside
Share
"Waterproof jewelry" is not just a marketing promise. This is the result of specific materials, technologies and quality control . It is the difference in the process that determines whether a piece of jewelry will darken in a month… or look like new for years.
This is how truly waterproof jewelry is actually created.
Step 1: Choosing the right foundation
It all starts with the material.
Waterproof jewelry is not made from brass or cheap alloys because they:
. rust . react with water and sweat . cause allergies . destroy the coating from the inside
Therefore it is used:
. 316L medical stainless steel . material that does not rust . does not oxidize . does not darken . it is safe for the skin
➡️ This is the foundation. Without it, there is no water resistance.
Step 2: Precision metal processing
Before any coating is applied, the metal is:
. shapes precisely . smooths to perfection . polishes evenly . cleans from microparticles
➡️ If the surface is not ideal, even the best coating will not last .
Step 3: PVD coating – the key point
This is where the real magic happens.
PVD (Physical Vapor Deposition) is not standard gold plating.
The process includes:
. vacuum chamber . gold evaporation . molecular bonding to the base . uniform and dense layer
➡️ The coating does not "lay" on the metal - it becomes part of it .
Why is PVD coating waterproof?
Because of the way it was applied:
. does not peel . insoluble in water . does not react with sweat . withstands daily friction
Therefore, PVD technology is also used in:
. luxury watches . medical instruments . premium accessories
Step 4: Quality Control
True waterproof jewelry is tested , not just described.
