Ring Size Measuring Tips
Our dominant hands are generally slightly larger — make sure you measure the right finger on the correct hand.
Rings with wider bands will fit a bit tighter. If you plan to measure one of your partner's rings, try to measure one with a similar width as the ring you want to purchase.
Make sure the finger is at normal body temperature — fingers can shrink or expand when hot or cold.
Your fingers tend to change size throughout the day — the best time to measure your finger is the end of the day.
If your knuckle is bigger, take 2 measurements and choose a size in between — ring needs to fit over knuckle but not be too loose or it will shift around.
When you don’t know your partner’s ring size, selecting one of the standard ring sizes is your best choice. The average ring size for women is 6 to 9, and the average ring size for men is 9 to 13.

Dainty yet beautiful. Looks very vintage and being rose gold made me love it even more. Detailing is stunning. Shipped fast and packaged so well. Also loved the ring box that was included. Will be a returning customer for sure!
I got this set as a holiday gift for my wife and me. The experience ordering and shipping were exeptional. The rings are beautiful in person and came packaged very thoughtful. My wife loves everything about her ring. The coffin shape and color combination are a statement piece. The engraving looks very delicate and gives the rings a nice intimate detail.
Utterly stunning ring! Im very happy with the diversity in ring size as my wife has quite the difficult finger to shop for. She loves it so much! Do keep in mind that this particular stone is more blue in white light, but other than that it is a lovely piece.
