Ring size guide
Our rings are crafted according to your measurements, so we kindly ask you to take the time to accurately determine your finger size. If you're unsure, please don't hesitate to contact us.
However, we strongly recommend having your finger size measured by a professional jeweler before making any online ring purchase.
1. How to Measure Your Ring Size by Yourself
You can measure your ring size at home using one of the following methods:
A. Measuring with a String or Paper
- Wrap a piece of string, paper, or a flexible measuring tape around the base of the finger where you will wear the ring.
- Mark the point where the ends meet.
- Measure the length of the string or paper (in millimeters) using a ruler. This is the circumference of your finger.
- Use the Ring Size Conversion Chart below to find your corresponding ring size based on the circumference.
B. Measuring with a Ring You Already Own
- Choose a ring that fits the finger on which you want to wear the new ring.
- Measure the diameter of the inside of the ring using a ruler (in millimeters).
- Compare the measurement to the Ring Size Conversion Chart below to find your ring size.
2. Tips for Accurate Measurement
- Measure your finger at the end of the day when it's at its largest. Your finger size can change slightly depending on the time of day, temperature, and activity.
- Avoid measuring cold fingers, as they may be smaller than usual.
- If you're in between sizes, we recommend choosing the larger size for a more comfortable fit.
