Eagle's Eye / Bird's Eye Beads
Eagle's eye beads are a silvery grey fibrous quartz in the same family as tiger's eye and hawk's eye, with the same rolling band of light across each bead. It is also sold as bird's eye or grey tiger's eye. This collection holds natural eagle's eye in a range of finishes and shapes for bracelets, necklaces and earrings.
Appearance
The body color runs from pale silver through steel grey to blue-grey, with darker fibrous streaks and a bright chatoyant band that moves as the bead turns. Some strands lean cool and bluish, closer to hawk's eye, while mixed strands add golden brown fibers and look like a softer tiger's eye.
The shimmer depends on smooth curves, so polished beads show the strongest moving band of light. Faceted cuts chop it into small flashes, and a matte finish calms it to a satin grey. At 7 on the Mohs scale it is as hard as other quartz and wears well in daily bracelets. The fibers are sealed inside the quartz, so polished beads need no special care.
Formation and origin
Eagle's eye formed the same way as tiger's eye: quartz grew together with fibers of crocidolite, a blue amphibole mineral, locking them in place, and the parallel fibers scatter light into a bright band. In tiger's eye the iron in the fibers oxidized to golden brown; in hawk's eye and eagle's eye the fibers kept a blue-grey to silver color, with eagle's eye the paler, greyer end of that range. The name is a trade name rather than a mineral species, and some dealers apply it to strands that mix golden and blue fibers. Most comes from the Northern Cape of South Africa, with further material from India and China.
Pairings
Golden sheen obsidian beads: black glass with a gold shimmer next to grey quartz shimmer, 2 moving lights together.
Bronzite beads: warm bronze flecks on brown against cool silver grey, in the same earthy, understated range.
Black onyx beads: a solid black that makes the grey band of light read brighter, and both are quartz.
Meaning and Metaphysical Beliefs
Eagle's eye meaning follows the older lore of the eye stones, which were carried as charms against the evil eye and worn for keen sight and courage. In modern crystal traditions the grey variety is associated with perspective, calm judgment and release of old habits, and it is often placed with the third eye and root chakras. These are traditional beliefs, not claims of physical effect.
