The collection of silver jewelry in 925 Sterling Silver and is 100% nickel-free and our leather products are all in genuine leather. Silver will be with time black, as it is affected by hydrogen sulfide which is in the air. It is completely natural and can often sanded away with a silver polishing cloth. Part of our range is also coated with a finish that increases resistance to enter, improve wear resistance and or decorating and enriching.
Below you can read about the different types of finishes and coatings. For more content, you can read on http://www.bridgat.com/shop/belly-chains/:
Oxidation or oxidation is a chemical process, which gives a little more raw finish (matte black) of the jewellery that many care about. It gets an antique finish and give a nice vintage effect.
E-coating, also known as electro-coating, is a method that uses electric current to coat a metal surface with an organic lacquer. It covers every nook and cranny on the jewellery with a smooth and uniform protective layer, which thereby increases the life span and increases the durability of the jewellery.
Applied as a coating of Silver gives Rhodium a white-gold-colored surface with an exceptional good durable finish.
Ruthenium coating gives the jewelry a “high-tech” black or grey cool appearance – a little more than oxidation. Black ruthenium-plated jewelry gives a much darker color than rhodium plated jewelry as well as a slightly tougher coating than rhodium. In addition, can effectively prevent scratches and wear on the ruthenium surface, which makes ornaments more durable.
