The Four C's – Cut, Colour, Clarity and Carat


It is important that your ring fits comfortably on the finger you intend to wear it on sliding over your knuckle but not so loose that it falls off. For the best results measure your finger size towards the end of the day and when your fingers are warm as your fingers are smaller in the early morning and when cold.

If you can, try to measure your finger size a few times during the day to ensure your measurements are absolutely right.

One of the easiest ways to measure your ring size is with Brillian's measuring tool. Simply wrap the plastic band around your finger, tighten it and slip it over your finger. Make a note of the letter that the arrow is pointing to and that is the size of ring that will fit you.

If you are buying a ring as a surprise

Ask close friends or relatives if they know his/her ring size. See if you can 'borrow' the ring which you can send to us and we will measure it and send it back to you.
