About the material:
-Silver stainless steel NEVER loses its natural color
-The gold color on gold plated stainless steel is just a plating on silver stainless steel and it CAN wear out or come off after a while exposing the silver underneath. This is because the plating comes in a varying level of quality and is also based on the thickness of the gold coating.
-Also oils, chemical, make up and skin conditions like high PH levels, can be the cause of discoloring.
❌Most people keep their gold plated stainess steel jewelry for years and keep it on daily without it losing its original color.
