Elegant Gold-Toned Necklace it says 14k but I’m not sure it is

This elegant gold-toned necklace adds a touch of sophistication to any outfit. Perfect for any occasion. I will not say it’s gold. I don’t think it is. I think it’s gold plated but it has like a 14 k looks like a GB or something. I’m not sure something or something like that I don’t know what it is. I can’t see it very good so it might be gold plated.
