Zultpedia operates a three-tier source hierarchy. Tier I: primary mineralogy and major gemological authorities (Mindat, GIA, IGS, Mineralogical Society of America, Wikipedia for peer-reviewed mineral pages). Tier II: peer-reviewed papers and recognized gem-trade publications (Mineralogical Magazine, Gems & Gemology, the Hatipoğlu et al. 2010 study). Tier III: trademark-holder and commercial claims (Zultanite Gems LLC, retailers), cited only with explicit attribution.

Why this is published

The Zultpedia Editorial Board signs methodology entries to make the editorial standards of the archive transparent. Readers should understand how facts get into the archive, what evidence supports them, and how disagreements among sources are handled.

How this applies in practice

Apply this to any specific entry on Zultpedia by checking the source-priority tier, citation list, and last-fact-checked date at the foot of the entry. Where ambiguity exists, the methodology page is the canonical reference.
