Zultanite may be called a diaspore variety, but it's technically a trademarked name for color-changing diaspores sourced from Turkey. Turkish diaspore gems have the highest quality of any diaspores. Besides Zultanite, the name Csarite is also a trademarked trade name for Turkish diaspore gem material.

Diaspore, also known as Zultanite or Csarite, is a unique and relatively rare mineral that belongs to the oxide mineral group. It is valued for its remarkable color-changing properties and its use as a gemstone. Diaspore is known for its ability to exhibit different colors depending on the lighting conditions, ranging from a yellowish-green in daylight to a pinkish-red or purplish-red under incandescent light.

Diaspore is a hydrous aluminum oxide with a chemical formula of AlO(OH). It was first discovered in 1801 in the Ural Mountains of Russia, and its unique color-changing properties make it highly sought after by collectors and gem enthusiasts. The gem-quality diaspore is generally transparent to translucent and has a vitreous to sub-adamantine luster.

While “Zultanite” and “Csarite” are trademarked names associated with specific sources of diaspore, the mineral itself is still known as diaspore within the scientific and mineralogical communities.

    Responsive seller, which is appreciated. Lovely gem. The only issue was with shipping. I paid for post but it was sent via Fedex. Fedex (of course) charged me illegal fees over a month after delivery! This was why I chose post and not Fedex.
