Diamond grading you can trust

Our clients often ask us the diamond cut used in our jewellery. Where a cut grade applies, it will appear on your diamond certificate. Please note that our diamonds achieve a minimum of a VERY GOOD CUT. This ensures the maximum amount of brilliance from your diamond. Excellent cut diamonds can be provided upon request.
