Tips for Buying a Ring for Someone Else

If you don't know the ring size of the person receiving the ring, here are a few "sneaky" tactics for finding out while still keeping your big plan a secret.

  • Just put one of her rings on your own fingers. Push it down as far as it will go and then mark the spot with a pen, or try to remember how far down it went. Then quickly go get that part of your finger sized.
  • Talk to her friends or a family member; it's not uncommon for a friend to ask another what their ring size is or to try on a ring they wear all the time.
  • If she has ring that she wears at times, borrow it and take it to a jewelry, they are happy to help you find out the size and then determine what her ring finger size is, they will at least come close.
  • If you are measuring with one of our tips, do measure it a few times to be sure.

Re-sizing Your Ring

When you receive the perfect ring but find the ring fits too loose or too tight, it is time to get resized. Make sure you take it to a reputable jeweler and if it is platinum make sure the jeweler has the machinery to work on platinum. Fingers get swollen during the summer, making a ring that is perfectly sized seem tight and uncomfortable. When sizing a ring, the most important thing is that it is comfortable. A proper fit means the ring can pass easily over the knuckle with enough contact between the ring and finger to keep the ring upright, but not so much that the ring feels tight.

  • Keep in mind an eternity ring must be very close to the correct ring size as most eternity rings are not sizable.
  • Most rings can be sized up or down one finger size. Ask the jeweler to see if this is also the case with the style you have chosen. We will be happy to re-size your ring, this could take up to 10-14 business days. A fee may be required based on what needs to be done.
