We use 316L surgical grade stainless steel alloy for our stainless steel chains, they are hypoallergenic and will not cause any allergic reaction on any skin types. Since our stainless steel chains are all made from solid stainless steel without any plating, they will never change color or turn your skin green, they really do last forever and give the wearer the peace of mind. All our stainless steel chains come with lifetime warranty against craftsmanship defects. This stainless steel chain has a chrome color very close to silver and white gold jewelry. It features a lobster claw clasp for secure closure. Another benefit of stainless steel chains is that it is relatively tarnish and corrosion resistant, compared to most silver or costume jewelry, so it can be worn in the pool or in the ocean, without the risk of tarnishing. It is the best choice for people with active lifestyle.
