Mini necklace oval blue light fusion.

Water Resistant /Stainless Steel: This is the highest quality of them all. Styles plated over stainless steel are non tarnishing, hypoallergenic and waterproof. You still want to wipe off at the end wearing it with a small jewelry cloth.

Gold Filled: Thicker coating of gold. Gold filled items will wear longer than gold plated pieces but still need some love as these items are not 18k solid gold. Use a mild jewelry cleaning solution and run under water and pat dry. Gold filled can still get dull and fade if there is heavy wear, constant perfume/hair chemicals, sea salt water and chlorine are constantly getting on it.
