Identifikation
Die Einträge zur Identifikation auf Zultpedia behandeln, wie sich echter Farbwechsel-Diaspor türkischer Herkunft von synthetischem Farbwechsel-Saphir, Farbwechsel-Granat, Farbwechsel-Fluorit und natürlichem Diaspor anderer Fundorte unterscheiden lässt. Enthalten sind das Feldtest-Protokoll, der Einsatz von Dichroskop und Refraktometer, die Auswertung von Laborberichten sowie die laborgestützte Spurenelement-Analyse (LA-ICP-MS).

Zultanit-Laborberichte — warum „keine Behandlung“ die dokumentierte Norm ist
A genuine Zultanite (color-change diaspore) laboratory report from GIA, IGS, or a recognized national lab will explicitly state "no evidence of treatment" in the treatment-disclosure section. This is the documented norm for…

Optischer Charakter von Zultanit — Zweiachsig positiv
Zultanite is biaxial positive: light traveling through the crystal splits into two rays with three principal refractive indices (nα 1.682–1.706, nβ 1.705–1.725, nγ 1.730–1.752), with nβ closer to nα than to nγ.…

Warum Zultanit unbehandelt verkauft wird
Color-change diaspore is sold without heat, irradiation, fracture-filling, or surface coating treatments because none of those treatments would produce a useful effect: the alexandrite optical phenomenon is structural and chromophoric, not amenable…

Zultanit vs. Opal — Farbwechsel und Farbenspiel
Zultanite shows color change (the same crystal showing different colors under different illuminants) caused by trace iron and chromium absorbing different wavelengths from each light source. Opal shows play-of-color (rainbow flashes from…
