"Darkness and Light on the Lake" is the latest (and last, for now) episode of The Diamond Disruptor podcast mini-series, "Sustainable Fashion: What You Need to Know," in which we talk to fashion brand leaders and experts who create clothes with environmentally-responsible materials.

On the Diamond Disruptor podcast, writer and host Clark Watts takes a continuing look at cultured diamonds as a sustainable option in luxury jewellery. Geared towards both industry novices and experts, the DD pod features interviews with jewellery brand leaders, analysts, scientists and more, as well as guests from other marketplaces who promote sustainable interests.
