One carat and smaller diamonds are down in price 10 percent to 25 percent over the past year. Synthetics have taken over the near-gem market and also still hold about 50 percent of the U.S. engagement ring market. Sanctions and tariffs are restructuring the supply chain. De Beers is for sale. How will all this play out in 2026? Martin Rapaport addressed the critical subject as a keynote speaker during CIBJO's Jewellery Industry Voices series at VIZENZAORO on January 18, 2026.

The Gold Principles Group (GPG) is a collaborative body uniting major participants in the global gold sector to promote responsible and sustainable practices, building on the Gold Industry Declaration of Responsibility and Sustainability Principles launched in 2022. It focuses on ESG (Environment, Social, Governance), sourcing, climate change and artisanal mining, with the aim of build trust and ensuring a transparent and ethical gold value chain from mine to market.

Marking the imminent release of both CIBJO’s comprehensive ESG & Sustainability Reference Guide for the Jewellery Industry and version 2.0 of its Responsible Sourcing Blue Book and Toolkit, the Jewellery INdustry Voices session at VICENZAORO on January 17, 2026, explored the journey from building solid ethical business foundations, to allowing jewellery companies better manage the potential risks in their supply chains, and consider the possible wider impacts of their businesses and how they might contribute to positive social and environmental outcomes.

The discussion panel, which was a highlight of the CIBJO Jewellery Industry Voices series on at VICENZAORO on January 17, 2026, looked at how the jewellery industry can educate and engage the next generation of consumers, helping them buy with confidence and make informed decisions.
