The IGDA welcomes the engagement of Vivien Johnston Glass as Sustainability Chair.
The IGDA was founded in 2016 as a US corporation and is a non-profit Association formed to serve as a central point for communication, education, and development of the laboratory grown diamond industry. It represents industry leaders from every sector of the laboratory grown diamond supply chain and from over a dozen countries worldwide.
IGDA President, Joanna Park Tonks comments,
“On behalf of the Leadership Committee and membership of the IGDA, we are thrilled to welcome Ms. Johnston Glass as Sustainability Chair of the IGDA. As sustainability moves increasingly up the corporate agenda, we demonstrate our commitment to intellectual rigour and science based substantiation with sustainability issues. Ms. Johnston Glass brings with her a balance of deep subject matter expertise in the ethics and sustainability space and a finely tuned commercial understanding of supply chain dynamics in the wider jewellery industry. At the heart of our combined work, is serving the best interests of the consumer by communicating sustainability accurately, honestly and transparently at point of sale. My colleagues and I look forward to creating long term impact with Ms. Johnston Glass on the sustainability agenda”.

Ms. Johnston Glass comments,
“The grown diamond community has evolved dramatically in recent years and with that there are many claims being made about ‘green’ or ‘sustainable’ credentials. Consumers deserve to have accurate information available, with credible marketing claims and a 360-degree view of sustainability that is evidence-based, quick and easy to understand. IGDA members are committed to understanding what best practice looks like and to work to ‘raise the bar’ for the consumer. I feel excited and privileged to be part of this important work. We look forward to collaborating on these issues, especially with associations who have retailer membership such as NAJ and who share our commitment to integrity.”
