Rather than providing our own valuation certificates, every bespoke lab-grown and natural diamond piece is independently submitted to the International Gemological Institute (IGI) for assessment once completed.
Your IGI report provides an independent record of your diamond's characteristics and authenticity, offering an internationally recognised level of confidence.
At Harper Jewellery Diamonds, we believe in transparent, direct-to-client pricing. Our pieces are priced according to the quality of the diamonds, precious metals, and craftsmanship, rather than to achieve a predetermined valuation figure.
If you require a replacement valuation for insurance purposes, we recommend obtaining one through an independent registered jewellery valuer. This ensures an unbiased assessment based on current market replacement costs, as insurance valuations often differ from the original purchase price.
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.
