Highcarat Diamonds
What is a Diamond Certificate?
A diamond certificate, also known as a grading report, is an official document issued by an independent gemological laboratory such as IGI, IDT, SGL, or GIA. It provides a complete evaluation of a diamond’s characteristics, including the 4Cs — Cut, Colour, Clarity, and Carat Weight. This certificate provides assurance of a diamond’s authenticity and quality.
At Highcarat Diamonds, eligible jewellery pieces come with an authentic certificate from IGI, IDT, SGL, or GIA. We ensure that our lab-grown and natural diamonds are tested, verified, and graded by experts at these recognised laboratories for cut, clarity, colour, and carat weight. Our certification gives you more than just a diamond — it provides trust, transparency, and lasting value.

Understanding the 4Cs

Colour: The natural tint of the diamond, graded from D (colourless) to Z for accurate colour assessment.
Clarity: Measures internal purity and visible inclusions under magnification, ensuring high-quality standards.
Carat: The diamond’s weight, carefully measured to determine its precise value and authenticity.
Every Highcarat Diamonds piece is accompanied by a certification detailing all 4Cs with complete accuracy and transparency.
