Zircon is a Grade 23 jewellery with a luxurious colourfast, golden coloured PVD-coating. No gold or palladium is added to the formula. The colour is scratchproof and will not fade away. It has been tested for many years, whitout finding anyone that is allergic to the material.
24K real Gold is coated using a PVD (Physical Vapor Deposition) process.
The jewelry is coated in a heated chamber under high vacuum. Electric voltage applied will form a plasma in the chamber andthe introduction of various gases produces an ion bombardment. This bombardment atomizes the cathode material (24k real Gold)into tiny substances which are deposited on the jewelry. The result is a hardened layer, which is biocompatible. It can be autoclaved.
