Eurostar Diamonds - Trust & QualityExcellence. From every point of view. 

Our heritage and values have been instrumental in helping us become the leading diamond supplier of fine polished diamonds, precision calibrated diamonds and ideal cut Hearts & Arrows diamonds worldwide. We achieve true brilliance with measurably greater light refraction than ordinary diamonds.

Excellence, every step of the process 

Our dedication to excellence demands perfection, every step of the way. From the mine to the marketplace, from rough to polished. Because simply being good enough is not good enough for Eurostar Diamond.

We manage every step of the production process within the walls of our own facilities. We believe that the pursuit of perfection is best entrusted to ourselves. We therefore do not outsource any of our production from rough to polished. We even develop many of our own patented tools. As a result, every diamond we cut tells the Eurostar story; a story of quality, excellence and uniform consistency, time and time again.

Rough diamond procurement

Our close relationship and longstanding partnerships with key mining companies empowers us to source and distribute both volume and variety of high quality, natural and untreated diamonds at the most competitive prices. 

Eurostar Diamond is a De Beers sightholder for diamond import. That means that we can promise our clients the exact supply they need. 

 Maximising the potential of each gem 

Each Eurostar Diamond undergoes a stringent analysis in order to effectively extract every diamond’s greatest potential. Hand-cut and hand-polished in combination with stunning technology to deliver you the highest degree of perfection. Crafted to set a shining new benchmark, each and every time. And designed to transform each Eurostar diamond into a true masterpiece.

Hearts & Arrows

The Eurostar Diamond Hearts & Arrows diamond is a brilliantly beautiful, ideal-cut diamond that exhibits a distinctive, perfectly symmetrical pattern in the table. The uniquely beautiful brilliance of a Eurostar Diamond Hearts & Arrows diamond is the result of perfect facet alignment along all of the diamond’s angles. Each stone therefore refracts a maximum of light, yielding exceptionally breathtaking beauty, fire and brilliance.


GIA exists to protect all purchasers of gemstones, by providing the education, laboratory services, research, and instruments needed to accurately and objectively determine gemstone quality.


The Diamond Lab of HRD Antwerp was founded in 1976 to meet the growing demand for reliable diamond certificates or grading reports. It's the largest diamond lab in the world which adheres to the rules set by the International Diamond Council for grading polished diamonds. These rules have been approved by the World Federation of Diamond Bourses and the International Diamond Manufacturers Association, the industry's two leading representative bodies. 


A certificate from IGI represents the all-important 5th “C”: Confidence. As the world's largest independent gem certification and appraisal institute for diamonds, coloured gemstones and jewellery, IGI is a standard of excellence for industry professionals and consumers around the globe.
