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:
1. CIBJO-accredited
2. IDC-certified
3. Listed on RapNet and IDEX
4. 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.
