The enchanting sound of this wind chime is the result of a special tuning using the "golden ratio." This ratio, discovered by the ancient Greeks, can be found throughout nature. Turquoise gets its beautiful blue-green color from copper and aluminum. It is a process that takes tens of millions of years. In many Native American languages, the translation for the word turquoise is "sky-stone." The color turquoise contains the growth quality of green and the communication quality of blue. Inspired by the rich beauty of this attractive union, the Turquoise Chime blendes colorful beads with a faux turquoise windcatcher.
