GEMSTONE IDENTIFICATION
REPORT
Gemstone Identification Reports are requested for standard identification and verification of coloured stones, that includes species and origin of the material, detailed measurements, quality, weight as well as a photograph of the gemstone.
DIAMOND GRADING
REPORT
Our Diamond Reports cover the four C’s which are cut, colour, clarity and carat weight, as well as an in-depth diagram, which will give you a clear measurement and understanding of the diamond’s proportions
JEWELLERY GRADING
REPORT
The Jewellery Report, with a full-colour image, provide a detailed description of the item; it is also possible to include a price evaluation. This is a valuable service for retailers and private individuals, as the jewellery piece has been certified by an independent organization.
