We love this chandelier.  Originally purchased for a different room but ended up hanging it in a more prominent room to let others admire it too!  I love how your eyes go to it when you walk in.   I installed the crystals after we hung the frame.  I didn’t know initially there were 2 different crystal sizes until I placed the whole lot (same size) in the first styrofoam layer. The second styrofoam layer had a different crystal shape!   So my advice to anyone hanging is to alternate the 2 different crystals.  It looks beautiful!
