I ordered this for my mom for her birthday...we wear the same size ring (4.5-5) so I ordered a 5.5 thinking itll be enough room but when it came it looked more like a 4 (3.5 maybe). I contacted the seller and they're going to exchange it for a larger size once Ive returned this ring. It is a really beautiful looking ring and I know my mom will wear it often when she gets one in a size that fits. (Once it arrives Ill update my review.)
