Materials of INTERO jewelry

Materials of the jewelry

INTERO jewelry is made of high-quality materials, which are safe, do not cause allergies and do not change their color.

Swimming or showering is no problem!

Our jewelry is intended for everyday use - they last a long time.

We use:
- Three layers of 18-karat gold plating.
- Stainless titanium steel.
- Cubic zirconia crystals.

The high quality of INTERO jewelry is proven by careful attention to the production process!

Safe production: Nickel free.


Gold plating

INTERO jewelry is made of gold-plated steel.

Our jewelry is gold plated using a safe method that uses titanium

(and no nickel) included.

The method we use to apply the gold layer is called PVD (Physical Vapor Deposition).

The thickness of the gold layer varies between 0.03 and 0.05 microns.

Sustainability of the jewelry

Our jewelry lasts a long time.

They can be used daily : in the sun, in the sea and in the shower.

We tested our jewelry in a laboratory in salt water for two weeks.

In real life, our employees have been wearing the jewelry for over a year, swimming and showering in the sun.

That's why we've made sure our jewelry is free from impurities and water resistant.
