Love the chandelier. There are a lot of crystals. I put the ones that are on the very top and the ones in the middle on and connected the lights before we hung the chandelier. It would have been too difficult to do if I had waited. Once it was up I the row of flat diamond shape crystals in. That row you will be doing every other crystal  one large and then one small and repeat till done the directions didn’t include that info. Then you will have 40 round balls to connect. So exciting seeing it come together. The balls match the lights on the other lights in my foyer. Everything is Beautiful!
