Editorial Policy

Our mission

TurkishDiaspore.org exists to explain one gemstone clearly and honestly: colour-change Turkish diaspore, also traded as Zultanite. We aim for accurate, accessible, non-commercial education — a place to learn about the stone, not to be sold it.

Sourcing & methodology

Factual claims — species, chemistry, crystal system, hardness, optical behaviour, and origin — are grounded in recognised mineralogical and gemmological references such as Mindat, the IMA, and GIA-class literature. Where figures vary between reputable sources, we present typical ranges rather than a single false-precise number. Our approach is described in more detail on the Sources & Methodology page.

Independence

This is an independent educational resource published by Zultanium. It is not a sales channel, carries no advertising, and holds no affiliate or reseller arrangements that could bias its content. It is independent of, and not authoritative over, the Zultanite® and Csarite® trademarks; trade names are used descriptively.

Accuracy & corrections

We check facts before publishing and review pages as understanding evolves. If you find an error — a wrong figure, an outdated claim, a broken citation — please tell us at ✉. We correct verified errors promptly and update the page.

No fabrication

We do not invent facts, figures, sources, reviews, or testimonials, and we do not publish AI-generated reviews or fake endorsements. Claims are traceable to a real source; where something is uncertain, we say so.

Not professional advice

Our content is educational information, not professional gemmological, financial, or legal advice, and not a substitute for an independent laboratory report. See our Terms of Use.

Imagery

Photographs are representative; individual stones vary in tone and intensity, and lighting affects how colour-change appears. Illustrative images are labelled as such.
