A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Hawk's eye is a blue to blue-gray variety of the quartz 'eye' stones, characterized by parallel, fibrous inclusions (often crocidolite asbestos replaced by quartz) that create a silky chatoyant effect. It represents an earlier stage in the alteration sequence that produces tiger's eye, retaining more of the original blue tone. With Mohs hardness about 6.5–7 and good toughness, it is suitable for many jewelry uses.
