INTRODUCTION

Zultanite is the color changing variety of the mineral diaspore, an aluminum hydroxide discovered in the Ilbir Mountains of Muğla in southwestern Turkey.

Zultanite contains traces of iron, chromium, titanium and manganese. It is generally believed that the manganese is responsible for Zultanite’s color change.

Although it is possible that the first samples could have been discovered as early as the 1950’s, commercial mining of Zultanite did not begin until 2006.

Zultanite is named in honor of the 36 Sultans of the Ottoman Empire that ruled Turkey and beyond from 1299 to 1923.

This name pays tribute to Zultanite homeland and differentiates Zultanite from non-gem quality diaspore mined prior to 2005, this material was often heavily included, poorly cut and not suitable for fine jewelry.
