The light isn’t crystal, it’s plastic.  It arrived quickly but at least 5 of the decorations had flaws in them - scratches, cracks & breaks.  Really obvious when you put the light on & 2 missing due to breakages.  If I hadn’t had a sparky fit the light (needed electric cable chopping), I would have returned it. 
 Wayfair have been good, they sent us a replacement, which we have used to get a complete set but this light too has the same type of flaws, cracks and breaks.  The complete light looks ok.
