OP I was about to suggest you get a ring sizer at Tiffany and see what size it is first. Anyone who wants to resize should find out the current size the ring is at, and then you can tell them what size you want it at, buy knowing what size it is at the store you plan to resize it at. There are many rings that are 7, but since each jeweler does the job, there could always be variation. When you get your ring back from the new resize, pick it up in person and size the ring on the sizer stick to see how much your ring was shrunken or upped, then try it on. If there is any problems, it can be sent back right then and there. So anal, right?
