Would you like to know more about fancy coloured diamonds, diamond treatments or laboratory-grown diamonds and diamond spectroscopy? HRD Antwerp offers workshops designed to introduce you into the fascinating world of extraordinary diamonds and focus on ruby, sapphire and emerald.
Hands-on workshop Diamond Spectroscopy
Within the world of diamonds, one of the hot topics continues to be the one of synthetic diamonds. More and more undisclosed synthetic diamonds infiltrate the market: HPHT and CVD synthetic diamonds are mixed into parcels of natural stones and synthetic diamonds are more frequently mounted in jewellery pieces. The main problem the industry is now facing, is the detection of those synthetic stones, whether they are part of a parcel or mounted.
The solution to this problem is spectroscopy, the study of the interaction between matter and electromagnetic radiation, because the optical centres in synthetic diamonds differ from those in natural diamonds.
During this workshop, our instructors will explain the reactions of synthetic and natural stones to different wavelengths. You will also get the chance to actively measure and analyse diamonds.

Synthetic Diamonds & Fancy Coloured Diamonds
Up until the fifties, a colourless or nearly colourless gem diamond was by definition a natural one. In the eighties, the first laboratory-grown gem quality diamonds appeared on the market. The arrival of these synthetic stones brought about enormous challenges for scientists and researchers. They embarked upon an intensive search for new techniques to identify the true nature of a diamond: natural, treated or laboratory-grown.
What is a synthetic diamond? Why is ‘CVD’ such a hot topic? How many synthetic diamonds are produced? How can I recognize a synthetic diamond? Can a synthetic diamond be blue? Why are natural pink diamonds so expensive? What is a Fancy Colour? Why such diamonds have a different Diamond Grading Report? Is an irradiated diamond dangerous ?
In this 1-day workshop we will discuss the synthesis methods and discuss the characteristics of synthetic stones. We will also explain the colour origin of fancy coloured diamonds and how they are graded.
