Ring Size Guide
What’s My Ring Size?
We’ve just made finding out your ring size, a whole lot easier!
If you already have a ring (can be any!) which fits you well, you can send that across and we’ll make your favourite DiAi ring in the same size. Your original ring will be returned to you as is, with your DiAi order.
To measure your ring size yourself, here are the two methods:
- Measure An Existing Ring
- Measure Your Finger
How To Measure An Existing Ring:
- Take a ring that fits you well
- Place it on a scale and measure the inner diameter
- Use the chart below to know your ring size
The above ring (as an example) measures at 17mm, which means the Indian Ring Size is 13 (as per the chart below).
| Indian Size | US Size | Diameter (in mm) |
