DIAMOND GRADING

Authenticity verification and quality grading of unmounted diamond. Grading services include testing to determine whether material is a diamond, and whether it is natural or synthetic. All diamonds are tested for laser drilling, fracture filling, irradiation, and high pressure/high temperature (HPHT).

The gemstone Identification report professionally documents the results of a full examination of a material. The results detailed will identify the material examined giving such identifying characteristics as colour, clarity/transparency, shape, cut, dimensions, weight and a coloured photo. The report will also state whether it is natural or synthetic and if the material has been treated to enhance. <
