Certified up to 1 carat

While certification is only standard from 1 carat upwards, we provide every piece of jewelry with an official IGI or GIA certificate. Maximum transparency, always.

Real diamonds, consciously chosen

Our lab-grown diamonds are real diamonds. Chemically, physically and optically identical to mined diamonds, grown without compromise to people or nature. Hand-selected from the top 1% in quality, graded D/E/F in color and VVS+ in clarity.

Officially certified Dutch gold

Our solid gold is inspected and marked with official Dutch hallmarks in accordance with the Hallmarking Act. This gives you complete peace of mind about what you are wearing.
