These are super beautiful!  I will say I was told the manufacturer was contacted by Wayfair on my behalf because after reading reviews about how bright and undimmable they are.  I explained to Wayfair Professional that they did not dim after all at least with the dimmer I purchased.  I am confident that it the company has gotten so many questions about it that I will learn which dimmer to buy.   Will keep you posted.  It really is pretty in the day.  Without dimmer best saved for the "operating room."  Or just leave it off for looks.  Lol.  Will keep you posted on this.  For now I have to give it a 3 for the fact that it is very pretty.  It is also very light weight and our friend had it up in no time!
