Turning your neck green is an allergic reaction, it doesn't mean anything as far as not gold or gold, my mother's fingers turned greenish black from gold .if it sticks to a magnet it isn't gold or silver ,if it doesn't it just means the chances are better because it's a non-ferrous metal- non-ferrous metals don't stick to magnetics because their is no iron in them(But it could still be silver or gold plated over brass or anything non-iron). Iron is magnetic.(You also need a fairly decent strength magnet to be sure, but usually a chain which is light weight will move towards even a small magnet held up in the air.The best way to tell for sure is to go to a Jeweler to get it tested.
I just had back surgery. Everything I know about it is in the comments. I have answered many questions. And I can't be walking around. It says 14k Italy on both of them. Its 24 inches and it says I love you going all around it. I have worn it and my neck has never turned green or anything. Thank you. I just have to much jewelry so I decided to get rid of some. My husband likes to spoil me.
tested for 14kt, since there are pieces out there that are stamped and not 14kt, ( i personally had a bracelet listed awhile ago which i knew wasn't real but was stamped 14kt italy, And i listed it as a fake 14kt bracelet
