RAPAPORT... Provenance and lab-grown diamonds have dominated the industry's conversation for some time, but developments in 2019 have made them the year's strongest news themes. In the 13th edition of the Rapaport Diamond Podcast, the team discusses these developments - which are being driven by the majors such as De Beers and the Gemological Institute of America (GIA) - and their implications for the sector. We also provide some insight into what to expect during the coming busy month in the diamond trade.
