Certification

What is Diamond Certification?
A diamond certificate or grading report is an official document issued by a reputable gemological laboratory. It confirms that the stone has been professionally examined and assessed for quality based on its carat weight, colour, clarity, cut, and dimensions. This ensures complete transparency and confidence in your purchase.

Why is Certification Important?
Two diamonds may look identical to the naked eye, but slight differences in their grading can significantly impact their value. Certification provides you with the assurance that your diamond or gemstone has been independently evaluated by professionals, reflecting the true characteristics of what you’re investing in.

When Will You Receive a Certificate?
At Adrisya, all diamonds 0.30ct and above come with an independent certification. The type of certificate will depend on the stone:

• GIA (Gemological Institute of America) – for natural diamonds

• IGI (International Gemological Institute) – for lab-grown diamonds

• SGL (Solitaire Gemmological Laboratories) – widely used and recognised in the UAE region

• GRA (Gemological Research Association) – for Moissanite, offering proof of authenticity and grading

For diamonds below 0.30ct, a detailed specification report is provided, in line with standard international practices.

Which Laboratories Do We Work With?
We collaborate only with globally respected and independent gemological labs to ensure you receive accurate, trustworthy certification. These include:

• GIA – internationally regarded as the gold standard in diamond grading

• IGI – highly respected for both natural and lab-grown stones

• SGL – trusted widely across the Middle East and Asia

• GRA – the leading authority in Moissanite grading

These labs are known for their consistency, rigorous standards, and global reputation. Certification from any of these institutions adds not only peace of mind but also long-term value to your jewellery.
