Certification Policy

At Rêve Diamonds, we believe that trust and transparency are essential when purchasing fine jewellery. Every diamond and gemstone we offer is carefully selected, and wherever possible, independently certified by the world's leading gemmological laboratories.

Loose Diamond Certification

All loose diamonds above 0.30 carats supplied by Rêve Diamonds come with an official grading certificate issued by one of the internationally recognised laboratories — GIA (Gemological Institute of America), IGI (International Gemological Institute), or HRD Antwerp. Each certificate provides a detailed analysis of the diamond's key characteristics, including carat weight, colour, clarity, cut, and proportions.

Natural Colour Diamond Certification

All natural colour diamonds, including those below 0.30 carats, are also accompanied by an independent certificate confirming their authenticity and colour origin. These reports are typically issued by GIA, IGI, or HRD depending on the stone and its characteristics.

Tennis Bracelets and Small Diamonds

Most tennis bracelets and designs set with small diamonds are not individually certified, as the stones are generally too small for independent grading. However, each piece is carefully quality checked by our in-house gemmologists. A tennis bracelet can be custom-made using certified diamonds, or certified as a complete piece upon request.

If you would like your jewellery to be certified as a complete piece, we can arrange a jewellery certificate from a recognised laboratory upon request.

Gemstone Certification

It is possible to find certified gemstones through our search tool, particularly for larger or rare stones. However, most gemstones available for purchase are not independently certified. We always provide complete transparency regarding gemstone origin, quality, and treatment details, and can arrange certification upon request.

Our Commitment

Whether certified or not, every diamond and gemstone offered by Rêve Diamonds is ethically sourced and carefully inspected to meet our exacting standards.
