We bought several similar light fixtures from a big box store 10 years ago when we moved into our new house.  It had soft blue/green glass fitting into our decor.  Bad luck occured when my husband dropped the curved glass shallow dome hit the floor and fractured when my husband was on the ladder to change the bulbs.  We went back to the big box store for a replacement and found they no longer carried the item...nor any replacement parts.  We went everwhere looking for the replacement glass.  It was two years later looking at the bare light bulbs in the broken fixture.  I looked online at Wayfair and found something so similar...not matching, but close...and ordered the new fixture.  I love it!  Easy for an electrician to install and it looks great!  It's far enough away from another original fixture that it looks more like it fits in rather than matches.  I'm good with that!
