Metal is PVD gold 
(PVD gold (Physical Vapor Deposition) is a highly durable, eco-friendly coating process that molecularly bonds a thin layer of gold (18k) to a base metal (stainless steel) in a vacuum chamber. It is more scratch-resistant, hypoallergenic, water resistant and tarnish-resistant than traditional plating.
