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:

  1. 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.
  2. Make sure that the string is pulled snug for the best accuracy
  3. 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)
  4. Use the circumference or inner diameter column in the chart here to find your size

    So sparkly and beautiful!

    I mistakenly ordered the June-Alexandrite birthstone. The stones are the very palest pink, but are *so* sparkly! Customer service was ever so kind in helping me get the ring I meant to order (November-Topaz). Based on this ring and the first ring I bought (that one didn't fit, I needed a half-size bigger), this line of jewelry is phenomenal, and the staff is very caring.

    I love this beautiful emerald stone ring except that

    I wish it were available in a larger size. I can only wear it on my index finger. A size 10 would be most welcome and much more comfortable. It's a beautifully made piece.
