Frequently asked questions
Sizing details

We use standard US ring sizing but can help you confirm the right size in any other measuring scale (UK, Australian, European).

You can also provide us the inside diameter of a current ring in millimeters and we will be converting it to a US sizing.

When estimating a correct ring size, it is best to consult with your local jeweler. If this is not feasible, try to use a manual ring sizing guide to help figure out your size. *Please note this is only a guide therefore we cannot be responsible for incorrect ring size determination.

Production time

Our pieces take from 2 – 3 weeks to be finished. In times of a higher order number (Valentine’s day, Christmas time and similar) the production time can be slightly longer. Please plan to order accordingly.

Production time depends on the amount of stones on stock, in case of a custom design the production time is a bit longer.
