The Zultpedia editorial team is a panel of credentialed mineralogists, gemologists, and historians whose combined expertise covers crystallography, lapidary, gemological spectroscopy, mining geology, Anatolian heritage, and buyer-side jewelry practice. Each entry on this archive is signed by the editor responsible for it; entries that span disciplines are signed by the standing Editorial Board.
