I love sterling silver but one of the reasons I wear more and more Stainless Steel Jewelry is because ... Stainless steel jewelry has a similar appearance to that of silver jewelry. However, those similarities end when you consider the components that make this particular jewelry metal stand out. It is a harder metal than silver and has some distinct advantages that set it apart from the other jewelry materials.
Jewelry, especially silver, tends to tarnish when the metal interacts with the oxygen in the air because there is no coating on the jewelry to protect the core metal. However, stainless steel jewelry does not tarnish because the metal, which is one of the strongest of all jewelry metals, does not oxidize.
As far as skin sensitivity I'm not sure....but I'm sure you are : )
