Tiffany & Co - T Wire Ring in Yellow Gold - 18K Gold

I have owned this ring for 3 years and have worn it a couple dozen times. There are scratches on this ring, which I have pictured, but there are no other issues with it. This ring is 18K gold and I paid $1,400 CAD after taxes upon purchase. The ring is now selling for $1,600 CAD online before taxes. This ring has been kept in a temperature & humidity-controlled room and has been cleaned regularly with gold-safe solution. It has been in a pet-free and smoke-free home. I have the original receipt from this purchase.
