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 to guarantee its authenticity and quality.

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 to ensure consistent colour, clarity, and overall brilliance. A tennis bracelet can be custom-made using certified diamonds, or it can be certified as a complete piece of jewellery upon request. Please contact us if you would like to arrange this.

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. This process provides a full evaluation of the finished item, including the total diamond or gemstone weight, quality grades, and craftsmanship details.

Gemstone Certification

It is possible to find certified gemstones through our search tool, particularly for larger or rare stones. However, please note that 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 if required.

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. Certification provides additional assurance, but our commitment to quality, craftsmanship, and integrity remains constant across all of our creations.

For more information about certification or to request a specific report, please contact our team at info@revediamonds.com or visit one of our private showrooms in London (Mayfair), New York (5th Avenue), or Los Angeles (Beverly Hills).
