To Make A Big Deal Out Of Small Diamonds

About Us

Pinkusewitz Diamond Traders is an Antwerp based company specialising in small, perfectly cut round diamonds.

Sourcing the rough stones directly from DTC, Rio Tinto guarantees us reliable supplies from accredited origins.

We are among the very few companies who stock a full range of consistently assorted diamonds, so most orders are processed immediately for shipping.

Early membership with the Responsible Jewellery Council (RJC) reflects the commitment to ethical and responsible practices.

We know the value of a diamond and will never trade with anything other than the finest that nature has to offer.

Our Diamonds

We specialise in perfectly made high-end round diamonds.

Our permanent stock runs from: 1.000 pct. (0.50mm) to 3 pct. (4.50mm), D to H colour (I-L), IF to VS (SI). Anticipating our customers needs, we stock a large inventory for immediate delivery. Our affiliate offices stock sizes up to 10 ct in all shapes.

Our selections and assortments, whether by clarity, colour or size, are compiled using the latest diamond grading technology (Sarin and Sortoscopes). This assures our customers an unprecedented level of accuracy and consistency.

Using the M-Screen+ and GGTL-DFI in our factories and offices guarantees the authenticity of every diamond delivered.


Our Master Cutters have all been trained with an utmost care for quality and precision.

Our customers' growing request for perfection is being met by their skill and experience, assisted by the newest technologies available to the diamond industry.

The infrastructure and working conditions are similar to those of the most developed countries, giving a vital boost to the economic wellbeing of their communities.

Pinkusewitz Diamond Traders and our group factory, Ramkrishna Diamond Pvt. Ltd., adhere to the industry's Best Practice Principles (BPP), and are members of the RJC (Responsible Jewellery Council).
