Diamond Industry Faces Debate Over Natural vs Lab Stones
The annual debate over natural versus lab-created diamonds has reached its third iteration, with industry voices weighing in on a market that is rapidly shifting. The discussion, titled “The Great Diamond Debate III,” brings together experts from across the sector to address questions about authenticity, consumer preferences, and the future of diamond retail.
The “Big Picture” section opens with Angela Han, publisher of Jeweller, who examines the broader implications of the market’s evolution. Her perspective sets the stage for a conversation that spans technical, commercial, and consumer-facing concerns.
Samuel Ord, editor of Jeweller, contributes an in-depth analysis questioning whether diamonds will maintain their value over time. His piece explores the longevity of natural stones versus lab-grown alternatives, highlighting market uncertainties.
The debate includes technical perspectives from Robert Bouquet, an independent analyst who notes the growing popularity of lab-created diamonds. Joshua Freedman of Rapaport adds that consumer demand for these stones is rising, driven by factors such as cost and ethics.
Transparency remains a recurring theme. Paul Zimnisky, an independent diamond industry analyst, argues that natural diamonds must become more easily identifiable to compete. This aligns with Garry Holloway’s critique that the natural diamond industry needs to address its own challenges before criticizing alternatives.
The Science section features Dr. Gaetano Cavalieri of CIBJO, who calls for clearer distinctions between natural and synthetic diamonds. Ian Dun of the Gemmological Association of Australia stresses that education is key to helping consumers make informed choices.
Legacy of Clarity: GIA updates diamond reports to reflect market. Sally Morrison of De Beers Group highlights the importance of trust and transparency in shaping consumer confidence.
The upcoming 2026 Jewelers’ Suppliers Directory aims to support retailers with access to new products and trends. Industry leaders like Marty Hurwitz of the Grown Diamond Trade Organization and Feriel Zerouki of the World Diamond Council continue to advocate for ethical sourcing and consumer education.
