Independently Certified. Beyond Industry Standards.
At Harper Jewellery Diamonds, we go beyond industry standards by submitting our completed lab-grown diamond jewellery to the International Gemological Institute (IGI) for independent assessment and certification.
Rather than certifying individual diamonds alone, we seek certification of the entire finished piece, providing added assurance of its quality and diamond specifications.
Exceptional craftsmanship. Independently verified. Our promise to you.

Yes. At Harper Jewellery Diamonds, we go beyond conventional certification practices by arranging independent assessment of our completed lab-grown diamond jewellery by the International Gemological Institute (IGI).

For every bespoke lab-grown and natural diamond piece, we provide documentation outlining an estimated replacement value, together with the diamond grading and jewellery specifications. This can be submitted to your chosen insurer to assist with arranging cover for your piece.
Your jewellery is also independently submitted to the International Gemological Institute for assessment once completed. The accompanying report records the characteristics of the diamonds and details of the finished piece, providing independent documentation of your jewellery’s quality.
These documents serve different purposes: our replacement value estimate indicates the estimated cost of replacing your piece, while the independent grading report documents its gemmological characteristics.
