A chandelier is already a thing that falls, so water is a natural subject for it. Stream by Christian Lava drops more than seven kilometres of chain, on Terzani's account, from an undulating frame, so that from across a room it looks like water pouring over the lip of a fountain and freezing in place. Atlantis by Barlas Baylar takes on the same behaviour in fine brass chain.
Mizu means water in Japanese, and each crystal drop is shaped by hand in Tuscany. Italamp likens Carmen 728/100 to a waterfall. Icicles by Coen Munsters records the path of water through stone, and Siena by Schonbek falls in multifaceted crystal drops from hand-formed crystal arms.
Length is the point of most of these, so they suit a stair or a double-height hall. See The Stairwell.
