Some tips: Measure your finger at the end of the day. Do not measure your finger when your hand is cold. The most accurate way to determine your ring size is to find a ring that fits and bring it to a jeweler to determine it’s size.


If you do not know the size of the ring when you want to make the purchase remember Ultra Diamonds stocks rings in a standard size 7 for women and a standard size 10. If the ring is purchased with an ULTRA PROTECTION PLAN you can send the ring in for sizing after receipt. Just call the 800 number on your protection plan and you will receive a postage prepaid envelope to mail your ring in for sizing**. ** Some rings, such as those with baguettes cannot be sized more than 2 sizes up or 2 sizes down.
