Accuracy, Expertise and Experience

IDRC is a UK based diamond grading laboratory offering diamond grading reports and jewellery appraisals.

IDRC offers peace of mind that the diamond has been independently inspected and examined for authenticity and quality.

IDRC has a fully equipped grading laboratory, based in Hatton Garden. Our lab is operated by certified gemmologists who together combine multiple years of experience and knowledge in the diamond field in order to provide accurate and professional opinions.

Grading Methods and Tools

Here at IDRC, we handle the process of grading with great care and attention to detail. Each diamond or piece of jewellery that we handle is individually studied and acknowledged by our gemologists who, with their expertise will asses and grade according to international grading standards.

Diamond Reports

At IDRC we keep a databank of all the reports produced. An IDRC report represents the impartial opinion of unbiased professionals.

Our Diamond Reports give an accurate assessment of a diamond’s cut, colour, clarity and carat weight according to strict international standards.

Our diamond valuation report prices start from £60. However, we have a limited time offer – second valuation report half price!

I bought a loose diamond from a trader and IDRC said they could certify for me. It was amazing to see how it’s done and the level of experience they have. They even knew roughly how much I paid for it!
