Polishing & Rhodium Plating

Polishing a ring or any jewelry piece is one of the most important step of jewelry manufacturing. The true beauty of the jewelry product shows after polish and rhodium. If the polish is not done correctly, it could ruin a jewelry piece. For example, if the polish is too much, a ring can lose all the small details; it could weaken the prongs that hold the stones; eventually, the ring will start losing the stones. If the polish is not enough, the ring would not have all that sparkle and shine that it needs to have.

Rhodium plating is also a very important finishing touch for a jewelry piece. It adds a protective bright white coat of rhodium on surface of a ring or any jewelry piece made of gold or silver.
