Ring size chart

Once you have chosen the gemstone and the ring design, tell us the size so the ring is made to fit. A gemstone ring should sit so the stone rests against the skin, which is why a careful measurement matters.

How to measure

1

Visit a jeweller

The most reliable size comes from a local jeweller using a steel ring sizer. Copper and plastic sizers can read slightly off.

2

Use a ring you already wear

Match a plain band that fits the same finger to the chart below. Measure the inside diameter in millimetres, then find that row.

3

Paper strip, only as a guide

Wrap a strip of paper around the finger, mark where it meets, and measure that length in millimetres. That is the circumference. Divide by 3.14 for the diameter. This method often runs large, so confirm with a jeweller before you order a gem ring.

  • Measure the finger you will wear the ring on, at the end of the day when the hand is slightly warmer.
  • Measure from the start of the strip to the pen mark, not from the far end of the paper.
  • On the product page, choose the Indian size. Checkout stays in INR.
