About Dennis Luxe Jewellery: Crafting for three generations

Antwerp, Belgium — Dubai

For over three generations, our family has been dedicated to the world of fine diamonds.

Our Mission

The journey of a stone

One family follows every diamond from the factory floor to the finished piece. Four stops, no strangers in between.

  1. The factory

    Where it begins

    Each stone begins its journey in our RJC-certified factory, where it is prepared in full compliance with the highest ethical and quality standards.

  2. Antwerp, Belgium

    Selection

    From there, the diamonds travel to Antwerp, Belgium, the heart of the global diamond industry. Within our family business, every stone undergoes meticulous selection and final quality control. Only those that meet our uncompromising standards are approved for creation.

  3. Dubai

    The atelier

    The chosen diamonds are then sent to Dubai, where they are transformed in our private atelier into refined, handcrafted jewellery.

  4. Certified

    One piece, one certificate

    Every piece is individually created, and its diamonds are certified by IGI or an equivalent independent laboratory where applicable - authenticity, precision and excellence you can check for yourself.
