This chandelier is such a beauty.  It is a rare find and it is high quality. 
But the assembly diagram has reversed two steps which makes assembly ridiculously difficult, by releasing the individual wires before screwing them all in. Instead, do this to put it together easily in minutes: 
1. Insert the special LED bulbs into the gold ball.
2. Unwrap the 5 or 6 packs of six-wire-bundle. Do not cut the wires apart yet.
3. Screw all the bundles firmly into the holes on the ball.
4.After screwing all into place, cut the plastic bands that kept the wires clustered.

Keeping the wires bundled also lets them act as their own screwdriver, just twist them in, snug them tight. It helps to set the ball in a stable position, elevated from your work surface, or hang it, like from a clothes rod. I set mine in a tall clay flower pot after screwing in some wires. And know that the hanging wire cannot be made longer, so don't shorten it before you are sure how long it needs to be.
