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.
Our Unwavering Commitment to You
A dedication to exceptional craftsmanship, meticulously selected stones, and a discreet, highly personalised experience — from initial consultation to final delivery and beyond.
This is our promise to you.
