Diamond and colored stones: National conference of gemology - VII edition: Gemological characterization in support of an ethical and transparent market.

The VII Edition of Diamond and Colored Stones: National Conference of Gemology was held in Naples on June 16–17, 2025 (https://www.rivistaitalianadigemmologia.com/en/7th-conference- of-gemmology-naples-2025/schedule-of-naples-2025-conference/). The event brought together researchers and professionals from the gemmological sector, united in promoting gemstone characterization to support a more transparent, responsible, and ethical market. Hosted at the Real Museo Mineralogico of the University of Naples Federico II, the conference provided an ideal setting for reflecting on the present and future of gemology. With over 25 contributions from national and international speakers and the active participation of 120 attendees, the program offered a rich series of thematic sessions addressing key topics in the field. A dedicated session focused on tourmaline, particularly the Paraíba variety, presenting the latest developments on origin determination, heat treatment analysis, and advanced spectroscopic techniques. The coral session explored critical challenges including environmental sustainability, genetic traceability, and evolving international regula- tions. The diamond session covered subjects ranging from recent scien- tific advancements to ethical sourcing and financial evaluation. Further sessions highlighted cutting-edge analytical techniques for gemstone identification, the increasing importance of photomicrography in gemmological analysis, and the critical role of supply chain traceability, from extraction to cutting and final distribution. This conference served as a valuable platform for knowledge exchange and collaboration between the scientific community and professionals in the precious materials industry. Dedicated space for young researchers and emerging professionals, along with informal networking opportu- nities set in evocative venues such as the Coral Museum of Torre del Greco, fostered meaningful and lasting connections between academia, industry, and artisanal craftsmanship. The next edition of the conference is scheduled for 2026 in Pavia.
