The enchanting sound of this chime is the result of a special tuning using the golden ratio. This ratio, discovered by the ancient Greeks, can be found throughout nature. Lapis, also called lapis lazuli, is a beautiful blue-colored stone often found with veins of white marble. The ancient Egyptians used lapis to represent heaven. They made amulets ornaments and even ground it to be used as eye shadow. This shade of blue is the color of inspiration, sincerity and spirituality. We blended blue stone beads with a faux lapis windcatcher to create our beautiful Blue Lapis Chime. This chime is designed to hang from a string loop, rather than an O-ring. Material: Aluminum.
