Blue Tiger Eye Puffy Heart

This is a polished blue tiger eye heart. Blue tiger eye, also known as hawk's eye or falcon's eye, is a captivating variety of the quartz mineral characterized by its chatoyancy, or cat's eye effect. This phenomenon occurs due to the parallel intergrowth of quartz crystals with crocidolite, which is subsequently replaced by quartz while retaining the fibrous structure. The mineral exhibits a silky luster and a striking blue to blue-gray color, often with bands or streaks of gold, yellow, or brown. Blue tiger eye forms through the metamorphism of iron-rich quartz deposits, typically found in regions associated with large-scale tectonic activity.
