Surgical steel is hard-wearing which is perfect for everyday wear and regular wear because although it 'can' scratch, it will not scratch or break as easily as Sterling Silver.
Steal does not oxidise which means it does not tarnish or discolour and it does not require regular.
And gold color surgical steel is a material made of iron plating on top of surgical steel. Iron plating has a more durable, slow discoloration and hard to peel off than regular plating. It also called gold color plating.
