Rhodium plating
This is a technology when a piece of jewelry is coated with a layer of rhodium. Rhodium is a metal that is classified as platinum and is valued more than gold.
⠀
It is applied in such a thin layer that the original color of the metal does not change, and the jewelry only acquires a beautiful shine.
⠀
Rhodium plating technology protects gold and silver from damage and oxidation.
⠀
Rhodium plating is hypoallergenic, so after coating the product with it, it becomes safe for people who are intolerant to precious metals.
⠀
Rhodium is applied using a special electrochemical reaction. This process takes place in several stages: ultrasonic cleaning, degreasing with sulfuric acid and alkali, rinsing, steam generator, treatment with a special marker under the action of electric current or a special galvanic bath.
⠀
Rhodium plating looks especially advantageous on silver and white gold due to its whitish shine.
⠀
Rhodium plating is a coating, and therefore such jewelry should be cleaned without powders, sandpaper, hard sponges and other materials that damage the coating.
