Cory L Chaisson oh wow, i would like to know as well because my mother has one similar that has to be by the same artist. ours is unmarked... but the characteristics are unmistakable.
Here's a really effective way of grazing a stone wall with specialized fixtures that direct the light towards the wall and minimize the scalloping. We could find some that do that but more discretely than the product shown here.
You may find our Fizz Collection a similar design, and certainly affordable. You may find our 9-Light Adjustable Drop Pendant with Bubble Crystal Glass here: http://www.wegotlites.net/Fizz-Collection-9-Light-16-Polished-Chrome-Pendant-with-Etched-Bubble-Glass-E22729-89PC_p_36783.html
