I had it for maybe only 2 weeks and it’s already turning green within the “diamond” it must be the fake gold underneath the diamond that’s changing color.. it hasn’t changed color in any other area thought which is weird. I really loved how it looked and was happy with it before it changed color. It changed in a matter of hours of one day. I removed it from my nose in the morning to switch it out with another nose ring; later at night when I wanted to switch them back was when I noticed the color changed.
