E-coating, aka electro deposition or electro-coating, uses an electrical current to cover a metal surface with an organic lacquer.

The technique effectively covers every part of the jewellery piece so that it’s left with an even and consistent coat. The e-coating process immerses the jewellery into coating materials such as pigments and resins that have been dispersed in water. An electrical current is then passed through the mix which causes the materials to adhere to the surface of the metal.

After the metals are removed from the water solution, they are baked in an oven in order to make the coating hard and durable and then polished.
