Hi, all! I'm planning on buying a diamond tennis bracelet by the end of the summer, but I am ordering it from a website. The website has you select your bracelet size (7, 7, 1/2, etc. and they have smaller sizes you can select like 6, I believe 6 1/2.) and because I don't usually wear bracelets, I don't have a go to bracelet size. I really don't want to screw it up as this bracelet is going to be a lot of money to order a size too small or a size too big. And it would be more money and a pain in the butt to order it too big and then have to pay the shipping fees and send it back through the mail to be resized. I've seen a video or two online of how to measure your wrist with a paper measuring tape, but I'm still not 100% certain and I really want to get the size exactly right (since it's not like buying from a jewelry store, where I can just have it shortened 10 minutes away from my house if it's too long/too short, etc.). I have smaller hands and wrists than most people, and I can upload pics if anybody wants. My ring size is a 4.5. I was thinking of ordering a 6.75? Any help would be appreciated, thanks!
