All, as most of you know I am new to this and looking for the first "gold" ring. I found a wedding band the other day mens and it is copper and has a very light tint of Gold (almost looks brass) on the top above the two side ridges. I dismissed it as a cheap wedding band until a minute ago and I saw a picture of another band located and shown today. The one shown was gold from what I read and it also had copper color sides on it. I understand gold does not tarnish from Salt/sealife and remains it tru color. Is this correct or could it change colors from long exposure to the "briny life?" I guess I need to clean this baby up possibly? Thanks for the input
