Our top-commercial SI and VS assortments are available with a very good to excellent cut and symmetry but have been tailored to ensure good performance and consistency.

Measurement Tolerance

Using state-of-the-art sieves and machinery, we are capable of calibrating to 0.025mm – twenty five thousands of a millimetre. Our regular round brilliant cut assortments are supplied with a minimum tolerance of +/- 0.025mm and a total tolerance of 0.05mm.
