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.
