Tiger eye cabochon – South Africa

Tiger’s eye is a natural variety of quartz known for its characteristic golden-brown color and distinctive optical effect called chatoyancy. This optical phenomenon creates a narrow band of reflected light that appears to move across the surface of the stone as it is turned. Color shades range from light golden to dark brown, often with natural transitions and patterns.

The cabochon cut with its smooth, rounded surface allows the optical effect typical of tiger’s eye to be fully visible. The orientation of the mineral structure during cutting influences the intensity and direction of the light band. The polished surface enhances the natural luster and color depth of the stone.

Tiger’s eye formed through the transformation of the original mineral crocidolite, which was gradually replaced by silicon dioxide. During this process, the original internal structure of the mineral was preserved, allowing the characteristic optical effect to develop. The golden-brown coloration is caused by the presence of iron oxides.

The most important deposits of tiger’s eye are located in the Republic of South Africa, which is the primary source of this mineral. Material from this region is known for its pronounced pattern and intense coloration. Other occurrences are known from Australia, India, and Namibia.

Tiger’s eye belongs to the quartz group and has a hardness of approximately 7 on the Mohs scale. It occurs in compact form and is valued mainly for its characteristic optical effect and distinctive coloration.
