Tulip fixture in our Peleg Collection. It is available in a 3"x3", 9"x9" or a larger 9"x15.7" size. Best of all you can make a custom fixture with any size canopy with individual or multiple pendants, and any height. We also carry a nice selection of other Blown and Fused glass lighting.
I think that this was the company -- The Meier Brothers who are part of a group called Made in Pescadero. I suggest emailing them with the image and seeing if they can help you.
Good luck --
