Sizing Guide
Rings are created true to standard US sizing. For the best fit we suggest having your finger(s) sized. We offer a physical ring sizer as well! Alternatively, you may follow the steps below to find your best fit:
- Wrap a string around your finger where you'd like your ring to be or place the string across the inner diameter of a ring that fits you from end to end.
- Make sure that the string is pulled snug for the best accuracy
- Mark the spot where the string meets and measure with a ruler in millimeters (circumference) or measure the string's distance across the center of the ring (inner diameter)
- Use the circumference or inner diameter column in the chart below to find your size

- JoNell H.Verified Buyer5/11/25Rated 5 out of 5 starsI love it!!
My favorite cut of stone is marquis but when I find one the stone is usually large. Because I have small hands, I prefer small ones so the gemstones in this ring are perfect and alternating it with diamond stones made it pop. I chose the emerald stone because it’s my granddaughters birthstone, but because I love the ring so much the next day In ordered two more, one in amethyst ( my favorite color) and the other one diamond. I’m going to stack them so I ordered the diamond birthstone to separate the other colors. My rings are scheduled to arrive on Wednesday and I’m so excited. I’ve ordered many items from this store and I’ve never been disappointed.
