Diamond Grading Report

When it comes to diamond purchases, certification is everything. It’s the document that determines value, confirms authenticity, and builds trust between buyer and seller. That’s why at DCLA, we take it seriously.

Our Diamond Grading Report is used by jewellers, investors, insurers, and courts. It’s the most trusted certification document in Australia, issued by the only lab in the country that is:

  • CIBJO-accredited
  • IDC-certified
  • Listed on RapNet and IDEX
  • And backed by a written grading guarantee

To ensure precision, we require diamonds to be loose. We weigh each to the thousandth of a carat. For simple claw settings, we may remove the stone in-lab. For bezel or complex settings, removal may compromise the setting and this sacrifice will be communicated to the client.

What’s in a DCLA Report?

Every DCLA report provides a complete technical breakdown of the diamond, including:

Carat Weight, Colour and Clarity Grades
Measurements and Proportions
Stone Type: Natural or Lab-Grown
Treatments or Enhancements
Unique Certificate ID
Cut, Symmetry, and Polish
Transparency & Fluorescence Strength
Angles and Hue Characteristics

All assessments follow the International Diamond Council (IDC) standards, the most widely recognised grading system worldwide.

Important Notice – Laser Inscription

The DCLA uses the most advanced PhotoScribe cold laser inscription technology. PhotoScribe is the only company in the world that guarantees in writing that their patented “cold” lasers will not crack or fracture your diamonds.

If the stone has been laser inscribed, the inscription details will appear on the certificate. Check your certificate to see if your diamond is laser inscribed. Browse this certificate guide to see where this would appear on your certificate.
