Complete 4Cs –carat, clarity, colour, cut- grading of natural diamonds can be carried out by SSEF. The diamonds must be loose and cannot be graded in a mounted state. SSEF does not offer grading reports for synthetic diamonds.

We also offer grading services for coloured diamonds and authentication and quality control of small diamonds. The order forms for colourless, coloured and small diamonds can be found here.

For further information on these services please contact us.
