Getting Your Engagement Ring Size

At MiaDonna® we make your ring to the size you order, we do not re-size a pre-made ring. This is done to insure the highest level of quality. While nothing is more accurate than having your finger measured by a professional, using these below tools will assist you in determining the exact size you will need for your ring purchase.


Request a Ring Sizer

If you would like us to send you a complementary plastic ring sizer, please Click Here and we would be happy to send you one. Your ring sizer will be shipped via USPS and please allow up to 7 days for delivery.


Printable Ring Sizer

We realize that you may not know the ring size for a given finger and we want to help. We provide a printable ring sizer that can help you determine the appropriate ring size. Click here to download the PDF. Prior to printing, ensure that page scaling is set to "none" in your print dialog box.

Here are some tips to make your ring size measurement more accurate:

  • Confirm the printed paper size with a ruler.
  • Pull tightly. The sizer must fit snugly to produce an accurate size.
  • Don't measure cold fingers. This is when fingers are their smallest.
  • For the most accurate reading measure your finger at the end of the day when it is largest.

Please note: while both the ring sizer and printable ring sizer are great tools, nothing is more accurate than getting sized by a professional jeweler. Please take into consideration the band width of the ring you are purchasing as ring size can vary based on band width.

Tips for Buying the Ring as a Surprise

If you are buying it for a loved one then this is where it gets a little tricky! You may want to use one of these suggestions.

Borrow one of your partner's rings (from the correct finger). Use the Ring Sizer PDF on this website to determine the size.

Make an impression. If she's in the habit of leaving any of her rings lying about, make an impression of one. A bar of soap, a piece of clay or even a piece of bread can be used to take a reliable measurement.

Trace the inside. You can even trace the inside of the ring on a piece of paper, which can be used to determine an accurate measurement.

Try it on for size. Simpler still, just put one of her rings on your own finger. 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. A friend of your loved one can be of great assistance in this particular endeavor. It's not uncommon for one friend to ask another for their ring size as a matter of curiosity. But remember to pick the "secret-keeping" friend!


Ring Sizing

We hope these are helpful tools to help you find the prefect size for your PERFECT RING! If all this fails, we will be happy to help. At MiaDonna® we are full service jewelers and we do re-sizing in house.

If you would like to send your ring in for sizing, please contact us and we can set it up for you.

It is very important that you know the exact ring size you would like it to be re-sized to as sizing up or down more than half a size may compromise the integrity of the ring design. Should you need sizing that is more than half a size up or down, then we may need to evaluate your mounting first.

Cost:

  • Resizing within your 30 day trial is $25.00 plus return shipping.
  • Resizing another time is: 14K/18K Gold $35.00 (plus shipping) and Palladium/Platinum $45.00 (plus shipping).

Once payment is received (either via phone or emailed custom payment link) we will email you a PDF form with an authorization number as well as the shipping/packing instructions. When we receive your ring it will only take us a few days to resize and then we will ship back to you via UPS 2-day air, so the whole process with return shipping is about one week or so.


Adjustments

If you like one of our designs but need a special finger size, or perhaps your center stone is of a different size, or maybe you want a bi-metal (two tone) design; we offer wax adjustment capabilities. When you order an adjusted style from MiaDonna we never do adjustments in the metal. Because we start from the wax, all adjustments are made prior to casting and your custom piece of fine jewelry is manufactured to your specifications. Best of all, most wax adjustments do not increase our standard turn around times.


Wax Adjustment Request

  1. When placing an order for one of our items, and you wish to have us make some adjustments in the wax (other than finger size) you must speak directly to a customer service representative who will be able to assist you.
  2. Please be sure to provide your exact needs for the wax adjustment and get a confirmation from our customer service representative that we understand your request and that it can be accommodated.
  3. In some instances a wax adjustment cannot be done and a new model may be required.
