Kyanite Blue Feather Earrings. Blue Kyanite naturally grows in this feathery wing-like formation. We have it titanium plated to enhance its brilliant iridescence. Titanium is a natural metallic element found abundantly in the Earth’s crust. Titanium reflects the light and colors of nature, creating fleeting shades of indigo. We crowned nature’s work of art with a faceted Kyanite gem.
