- Description
Ceylon blue sapphires, each 3mm round, are paired with 3mm round brilliant-cut diamonds on this eternity ring, celebrating the depth of colour Ceylon sapphires are prized for alongside the diamonds' brilliance.
Each gemstone totals around 1ct depending on your ring size, and the design is available as a full eternity, with stones running the complete circle, or a 60% half-set version, which is a practical choice if you think your ring size might change over time.
Handmade in 18ct yellow gold, 18ct rose gold, or platinum, the ring can also be customised with pink sapphire, emerald, or ruby in place of blue sapphire. See more in the eternity ring collection, or book an appointment to discuss gemstone options.

How to measure
- You'll need a piece of paper or string about the same length as your ring finger.
- Wrap the paper or string around your finger and make sure it fits comfortably. Mark the string or paper at the point it meets.
- Carefully measure the string or paper in mm on a flat surface with a ruler – from the end to the mark – and enter your finger circumference in our size chart tool to find your ring size.
Another way to measure your ring size is to use a ring that you already know fits the correct finger.
- Print off our true-to-size guide – double-check that you print to scale using the paper size outlined for accuracy.
- Put your ring over the circles on the template to find your ring size.
