The 19th International Colored Gemstone Association (ICA) Congress, which convened in Bangkok from October 12 to 15, 2019, saw its largest ever turnout in its more than 30-year history. The event held discussions about pressing issues in the industry such as sustainability, responsible sourcing and challenges faced by artisanal and small-scale miners versus large-scale industrial mining. A series of speeches and panel discussions also touched base on new consumer and design trends and marketing opportunities in the digital era, as well as updated gemstones grading technologies and standards.
