The AUCLAIRE promise

Quality is never negotiable.

We select the very best stones for your wishes and budget. We would always rather do a little more than not enough — in the selection, the craftsmanship, and every finishing detail.

Because AUCLAIRE is a family business, every piece carries our name. It must be able to pass through generations and become part of your legacy — as it is part of ours.

Certified authenticity

No jewel leaves our atelier without its AUCLAIRE certificate of authenticity. Centre diamonds also include their GIA or IGI certificate.

Stones selected one by one

Each stone is evaluated for its brilliance, proportions, and true beauty — never only for what appears on paper.

A family house

Our reputation is built one piece at a time. We create today what future generations will be proud to pass on.

They took the time to understand our story. The result exceeded everything I had imagined.
Jonathan P. · 2 ct oval solitaire · IGI certified
