"The HRD CDG course is a very well structured, serious and intense course. I also chose this course because HRD is the leading European authority in diamond grading, which represents the maximum in the Diamond sector. Thanks to this course I have been able to enormously increase knowledge in diamond industry, my skills in diamond grading. In fact, during the course we had the opportunity to examine numerous diamonds of all grades and qualities. Furthermore, the course allowed me to acquire greater mastery in the use of the tools of the trade, and I had the opportunity to meet many professionals with whom to stay in touch and with whom I could have the opportunity to collaborate in the future. It is a course that I recommend to anyone who wants to increase their skills in the field of diamond classification."

"I had a fantastic experience during the course and the knowledge and skills I gained during it will be of real use for my business and for my career."

"I consider the course NECESSARY and highly educational for all those who want to increase and realize their diamond grader skills. I will use the skills acquired to take the selection of lots for commercial use to the next level and to pre-certify diamond lots (0.30 pt UP)."

"Not only did the classes at HRD Antwerp provide me with a new level of confidence with regards to my chosen profession, but HRD Antwerp’s prestigious reputation has significantly enhanced my credibility towards clients worldwide. Learning how to grade diamonds changed my perception entirely and enabled me to accurately assess and appreciate the quality of well-cut stones. Subsequently the rough diamond sorting & planning course sharpened my eye when it comes to buying in the field, an invaluable tool. The international aspect of HRD Antwerp made it immediately possible for me to reach out beyond borders."

"HRD Antwerp helped me to reach my professional goal thanks to its high level training programmes. Thanks to the Jewellery Design Course, I learnt to think out of the box and structure my imagination. The drawing techniques they emphasized are currently helping me present my designs in the most appealing way. By combining the Jewellery Design Course with both the Diamonds and Gemmology Courses, I am now fully confident about the gemstones I buy for my jewellery creations. HRD Antwerp is a fantastic education centre, a meeting point with international participants who can then become future competitors, partners or friends that will contribute to your success!"

“I first graduated from HRD Antwerp in 1998, and then in 2016, as a Graduate Gemmologist (Certified Diamond Grader and Certified Gemmologist). During each job interview I had, the HRD Antwerp diploma has been recognized as a major asset in the precious gems and jewellery Industry. The HRD Antwerp programmes are rigorous and intensive. They focus on practice while delivering a strong theoretical basis, in a relatively short period of time. The cutting-edge instruments used during the courses make the gem analyses very accurate.”

"The Contemporary Diamond Jewellery Design course allowed me to express my creative ideas and speak the “jewellery language”. The Gemmology and Diamonds diplomas are recognized worldwide and broadened my ability to be autonomous when buying gemstones for my designs. HRD Antwerp offers professional training courses directly linked with market trends and needs. The theoretical foundations and technical skills learnt are immediately applicable in the gems and jewellery industry."

"As a jewellery designer, I was very keen on taking the HRD Antwerp Certified Diamond Grader Course to expand my knowledge of diamonds to use in my designs. I enjoyed the balance between theoretical knowledge and practical skills during the course. The teacher had a very hands-on approach which helped me a lot to grow my diamond grading skills and my jewellery business. It was a great experience to discover the fascinating world of diamonds!"
