Hi all I'm new to the forum so first post. I have just noticed the skin around my wedding band going black like it does with cheap rings, I've had the ring 2 yrs with no marks and its definately real gold. I googled it and apparently it can be a sign of low iron- been nearly 7 wks since ive had bloods done and iron levels were fine. Just wondering has anyone else experienced this? I'm 16+5 btw.
