Ring Size Information

Rings in our collection are available in sizes listed in the item description. If your size is not listed, we can create a custom ring for you. Prices may vary from those on our website.

Custom-sized rings are made to your specifications within 3-4 weeks.

Measuring Your Ring Size

The table below shows size comparisons used in our ring manufacturing. Measurements are exact for the American system and approximate for others. Ring sizing gauges, finger gauges, and charts may not always agree.

Please note that measurements for thin bands are taken from the base of the band on the cone sizer, while thicker bands are measured from the middle. If you are unsure of your size, contact your nearest distributor for assistance or visit a local jewelry store for an accurate measurement.
