Ring Size Guide
Kindly observe: For the most accurate ring sizing, we recommend a jeweller’s professional measurement.
To determine your ring size:
- Employ a piece of string or dental floss and encircle it around your finger.
- Note the point where the string end aligns.
- Measure the entire length and cross-reference it with the chart provided.
- Prevent any stretching or twisting of the string.
- Repeat the measurement 3 – 4 times to ensure precision.
As a reference; sizes 5-7 are categorized as SMALL, sizes 8-10 fall into the MEDIUM range, while sizes 11-12+ are considered LARGE.
