Lab-grown diamonds at the heart of luxury by Rivka Nahmias

Welcome to Rivka Nahmias, your bespoke jewellery workshop in the heart of the Marais in Paris. We reinvent luxury by offering you the choice of ethical, lab-grown diamonds. These gemstones, of eternal purity and beauty, embody our commitment to our planet.
Each piece of jewelry is carefully handmade in Paris. From 0.30 carats, our diamonds come with IGI or GIA certificates of authenticity, guaranteeing their weight, cut, color and clarity.

Join the conscious luxury movement.
Choose the stone that reflects your most cherished values and desires.
Grown in a laboratory or extracted from the Earth, diamonds are eternal.
