The hawk’s eye stone is fibrous quartz, technically classified as a quartz pseudomorph that began life as crocidolite.
Generally, it’s an opaque or slightly translucent stone that readily accepts a polish, resulting in a nice sheen. Additionally, the fibrous elements create a visual effect known as chatoyancy.
Hawk’s eye is typically blue, with some pieces leaning toward gray while others may appear slightly green. The coloring is a result of reduced iron levels as the crocidolite transforms. When the iron levels remain high, the color ends up golden, and that version is called tiger’s eye.
Primarily, hawk’s eye is found in South Africa and Thailand, and those locations serve as the main sources of commercial hawk’s eye.
However, deposits have also been in Australia, Bolivia, Brazil, Canada, China, India, Korea, Myanmar, Namibia, Spain, and the United States.
