Frequently Asked Questions
Answers to common questions about Turkish Diaspore.
Yes. Zultanite is a trade name for gem-quality colour-change diaspore. Diaspore is the mineral species; Zultanite is the marketed gem grade of it from Türkiye.
Yes. All gem-quality colour-change diaspore on the market currently comes from Türkiye, so "Turkish diaspore" and "Zultanite" (and Csarite, Ottomanite, Turkizite) refer to the same material.
None gemologically — both are trade names for the same Türkiye gem diaspore. The difference is commercial: trademark, branding and price positioning.
Typically kiwi-to-sage green in daylight and champagne, light gold or raspberry-pink under incandescent or candlelight. The shift is caused by trace manganese and iron, not by any treatment.

Buy on documentation. Ask for an independent lab report identifying the species as diaspore with natural, untreated colour change — colour-change glass imitations exist, so a report is the reliable check.
