What does PVD jewelry mean?

Firstly, PVD means physical vapor deposition, also called vacuum plating or vacuum coating, so PVD jewelry means jewelry with PVD coating.

In detail, PVD coating technology for jewelry can be cathodic arc or magnetron sputtering. Cathodic arc is with fast deposition rate, but rough film particles, which is good for normal grade jewelry; Magnetron sputtering is better for high grade jewelry since it is with fine film particles, easy color controlling and low working temperature.

By the way, jewelry above is metal material. As for plastic, thermal evaporation would be better choice.
