description Hawk's Eye Overview
Hawk's eye is a blue to blue-grey variety of chatoyant quartz closely related to tiger's eye. Its silky optical band, known as chatoyancy, results from aligned fibrous inclusions that reflect light across the polished surface. The material develops through alteration of crocidolite-bearing rock and may contain areas transitioning toward golden tiger's eye. Hawk's eye is commonly cut into cabochons, beads, and ornamental objects for jewelry and mineral collections.
