If you don't know your size, there is one method my customers and I have been using and it works miracles 💅
You'll need a ring that already fits desired finger and a ruler.
1. Place your ring on a ruler horizontally across the widest part of the ring is on the edge of the ruler so you can see the diameter.
2. Measure inside of the ring from side to side (in mm). This will give you the ring diameter.
3. Find out your size using the table below.
