Eurostar Diamonds Traders NV


Eurostar is a leading global diamond manufacturer offering a consistent supply of the highest quality diamonds produced entirely in-house, from source to final product. Our portfolio covers the full spectrum including Eurostar’s highly coveted signature Ideal Cut Hearts & Arrows and other exclusive patented shapes in either select, or volume quantities along with a custom-calibrated precision product line.

We select only the best rough stones, analysed by highly advanced proprietary computer technology.

Nearly 4000 master artisans around the globe work with dedication to fulfil all our clients’ needs. Every diamond is hand-cut and hand-polished by one of our master diamond-artisans. We are the recognized expert in cutting and polishing all sizes of diamonds from stars (0.01ct) to the largest and rarest of stones.

Eurostar offers custom-made bespoke diamonds in collaboration with our own in-house product development team. Each diamond is manufactured according to strict, independently audited procedures and must pass no fewer than 32 quality checks. Our diamonds are made to the highest international standards and come with GIA, HRD and IGI certification and are naturally guaranteed 100% Kimberley Process compliant.

Flexible service, mutual trust and a meticulous attention to detail… these are the building blocks at Eurostar for lasting, mutually successful partnerships.

Corporate Social Responsibility

We take pride in our connection to the local communities where our people work and always operate within a relationship of mutual trust and respect. Our employees enjoy a wide range of benefits including comprehensive training. Our state-of-the art facilities in China and Botswana uphold the highest standards when it comes to fair labour conditions and are an important source of employment for local communities.

Eurostar funded the construction of the East Unicorn Nursery in Qigan town, China, providing care for around 250 children. In Botswana, Eurostar provides daily meals to the children of the Gamadubo orphanage.

Eurostar is certified under the Responsible Jewellery Council’s Member Certification System, another sign of our commitment to promoting and implementing ethically, socially and environmentally responsible practices throughout the diamond and jewellery supply chain, from the mine to the customer.
