Gemstone Type: Natural Diaspore,
Occasionally known in the trade as “Zultanite” or “Csarite”

Diaspore is an aluminum oxide hydroxide sometimes exhibiting color change between greenish hues in daylight and pinkish or yellowish tones under incandescent light. The phenomenon arises from trace elements that affect light absorption. Typically transparent when gem-quality, diaspore can be cut into brilliant faceted stones or cat’s-eye cabochons. With a Mohs hardness around 6.5 to 7, it’s moderately durable. Though not as common in mainstream jewelry, diaspore’s color-shifting charm captivates collectors.
