How Our Jewellery Certification & Authenticity Works

Evaluation by a Trained Gemologist, Diamond quality (cut, colour, clarity, carat weight), Gemstone type and treatments, Metal purity (gold karat, platinum grade).

Documentation & Certification After evaluation, the lab issues an official Certificate or Grading Report. This document typically includes:
A detailed description of the stone or jewellery, Measurements and weights, Quality grades (e.g., diamond 4Cs), Gemstone origin, Diagrams showing inclusions or unique traits, Metal purity verification, and A unique certification number. Certificates serve as a passport for the piece.
