This is a really fun necklace to commerate the Chakras. Depending on what you are wearing or how you are feeling, this necklace can be drapped long ways, or double as a smaller 16 inch collar. The turquoise colored chips are actually Howlite (relative of Turquoise) and the purple, Amethyst. The rest of the chips are an imitation glass. I love the way this "Rainbow" necklace brightens anyone's outfit.
