While lovely on its own, 21 was designed to hang in groups, like barnacles clustered on a rock. The Bocci 21 Series Multi-Light Pendant does the grouping for you, with three, five or seven of the distinctive shades sharing a single canopy. Each one-of-a-kind pendant included in the cluster features raw, translucent porcelain draped around an inverted trumpet of frosted borosilicate glass.
