This is a gorgeous piece, it’s a little bit hard to put the pieces together but Im telling you the fastest way . 
1- clean the crystals first and wipe it ( long crystals with water and detergent will be good for  more shine)
￼￼￼2- install the base and put the bulbs (the base is wrapped with plastic take it of , the base is mirrored love it )
3- put the crystals starting from number 1 than 2 until the end .
Looks luxury !
