You don't need a crystal ball - There are a lot of at home methods for finding your ring size when you are shopping for sustainable rings for yourself or a sustainable engagement ring for someone else!
Use the handy chart I use to figure out or double check your ring size.
Finding your ring size:
Click the chart below to open it in another window, right click to save to your desktop and then print it (don't change any of the scaling.) It should print at the correct size and there is a way to double check that it's printed to scale with a ruler. After you print, follow the directions on the chart, remember you need to see the entire black circle inside the ring!
Choose carefully! I offer sizing in half and even quarter sizes. When in doubt, err on the smaller size. It is easy (and fast) for me to make a ring a tiny bit larger if it turns out to be too small. If a ring is too large though, I have to start over and remake the whole piece and it will take longer for you to get your new jewelry!
If you want to be absolutely sure, you can order a handy, reusable ring sizer for $3 HERE
Finding out someone else's ring size:
If you're out shopping, try on some jewelry together so you can learn their ring size, and some of their preferences about metals and stones.
Peek through their jewelry, is there a ring that they already wear sometimes on their ring finger (traditionally on the left hand)? If so, borrow that ring! You can print the image above and match it up.
If they don't have a ring, buy that little ring sizer above and size their finger while they are sleeping!
Again, when in doubt, err on the smaller size. It is easy (and fast) for me to make a ring a tiny bit larger if it turns out to be too small. If a ring is too large though, I have to start over and remake the whole piece and it will take longer for you to get your pieces.
Now that you've got the size - shop the collection of celestial rings!
