In this episode of Diamond Debates, Avi Krawitz is joined by J.R. Dunn Jewelers President Sean Dunn to examine whether branding can counter an increasingly commoditized diamond market. The discussion explores why diamond branding has historically struggled, the relationship between category marketing and individual brand building, the growing importance of storytelling, origin and provenance, and how retailers can differentiate natural diamonds beyond the 4Cs.

From the Kimberley Process to sanctions compliance, traceability rules, AML requirements and ESG reporting, the diamond trade operates under layers of oversight that few luxury sectors face. Supporters argue regulation protects consumer trust and shields the industry from reputational risk, while critics say it adds cost, slows trade, and disproportionately burdens smaller players without solving core structural problems. In this discussion, Avi and Feriel Zerouki, president of World Diamond Council (WDC), explore whether these rules are strengthening the industry’s long-term credibility or gradually squeezing its competitiveness in an already fragile market.

In this episode of Diamond Debates, Avi is joined by Wes Tucker, CEO of Tracr, to unpack the proposition that the diamond industry must adapt to or risk decline by pivoting decisively toward value. The wide-ranging discussion explores structural shifts reshaping the market, from oversupply, mine economics, and geopolitical pressure, to changing consumer spending habits, the rise of lab-grown diamonds, and the growing importance of branding, design, storytelling, and traceability. Wes and Avi argue that broad, one-size-fits-all category marketing is losing effectiveness, and that future growth depends on clearer differentiation, higher-value product strategies, and more personalized retail experiences that reconnect diamonds with aspiration, rarity, and long-term emotional meaning. The conversation ultimately frames as a coordinated effort to rethink how value is created, communicated, and captured across the entire diamond pipeline.

Lyndon de Meillon is a diamond entrepreneur and geologist with interests in alluvial mining projects along South Africa’s Middle Orange River as well as Pioneer Diamond Tender House. He also serves as vice chairperson of the South African Diamond Producers Organisation (SADPO). Lyndon is deeply invested in the success of South Africa’s small-scale mining sector, which faces some unique challenges spanning the heavy regulatory environment, social issues in the country, the geological makeup of the Orange River and the global economy. He believes South Africa’s alluvial sector has 100 years of life left in it, and also that the country has at least one other major kimberlite mine waiting to be found. But much depends on how the industry and the country tackles those lingering challenges.
