Independent Gemmological Laboratory

Diamondsure is an accurate way to determine whether a polished stone is a natural or synthetic diamond, it will also determine if the colour of the diamond is natural or enhanced. By placing the diamond, table down, on a measurement probe and the visible absorption spectrum is measured and analysed. Results are displayed in just seconds. What's more, DiamondSure can be used on both mounted and unmounted stones from .10 to 10 carats.

In a matter of seconds, DiamondSure verifies type II diamonds, identifies all synthetics for further testing, including heat treated synthetics exhibiting the N3 absorption line, and determines synthetic moissanite.
