Jewelry wholesale supplier tells you why does jewelry fade

A Jewelry wholesale supplier tells you why does jewelry fade from a professional point of view today?

The typical jewelry base material is generally silver-copper alloy, which can oxidize and rust when used alone. It will plate on the outside of the metal base, gold platinum-plated or silver-plated.

A large part of the reason for the fading of jewelry is related to the color plating process. At the same time, to control the cost, the coating is generally skinny, expressed in microns. The gold-plated layer of good ornaments is 10-25 microns, and the thickness of the gold-plated layer of ordinary ornaments is 2-3 microns.

The typical color plating processes are plating technology and vacuum electroplating technology.

Plating /coating

Using the principle of electrolysis, a layer of other metals is the plate on the metal surface. Using electrolysis to attach a metal film layer to the metal surface can prevent metal oxidation and improve wear resistance, but the price is high.

Vacuum plating

Under vacuum conditions, various metal and non-metal films are deposited on the surface of objects by distillation or sputtering. Vacuum plating is fast and has good adhesion, but the price is high.

The plating of gold-plated jewelry is like makeup, it will fade over time, but good gold-plating technology and thickness will last longer.

Key point!!!

How do you judge the gold-plated craftsmanship of gold-plated jewelry with the naked eye?

Generally speaking, the surface of the jewelry is uniform in color, full in bloom, without any oxidation spots, no bubbles, and no leakage plating. No burrs, grit when touched by hand.

The thicker the gold-plated layer, the fuller and more textured the overall look of the jewelry.
