Blue Nile has a great ring size chart you can print out to use to tell exactly what size this ring is and let everyone know so they don't bid on something that won't fit. I put the link below for you and hope it helps. I use it all the time when I'm listing rings. Thanks & I'm watching and hoping it's a 7!
Not usually... I was informed that If u wear costume jewelry you should always remove it before washing hands or doing anything involving contact with liquid to prevent the ring from leaving a "green" mark on your skin. Either way Soap and water will remove any discoloration left on skin.
It is no problem, I can refund and relist. In the future it would be wise to read all the information on the auction page before placing a bid to avoid situations such as this. Thank you and have a great day.
