Re: 電卓 Another method by Engagement Rings which black jewelry is produced is electroplating, usually with black rhodium or ruthenium. This can coat the surface of jewelry to give it a black finish. An advantage with black rhodium 14K Gold Chain plating is that it can be performed on selected parts of a jewelry piece. For example, a ring set with black sapphires can be plated with women dress black rhodium around.
