This PDF Poster 'Gems of the Western Hemisphere' Is Yours to Download, Free

Of the 363 species of hummingbirds in the world, more than 50 are named after gemstones. The sparkling qualities of hummingbirds and gemstones are created by the degree to which they bend the path of light. Diamonds curve and refract light as it enters and bounces around the gem’s interior. The red gorget of a Ruby-throated Hummingbird gets its shininess from the interplay of light and intricate nanoscopic structures inside the feathers. By bending light in extreme ways, many hummingbirds literally look like flying jewels—hence the references to sapphire, emerald, and other gemstones in their common names.
