Miracle Celtic Brooch, Mid 20 century

Hello Everyone.
I found this Miracle brooch today at my local donation store, first I thought Egyptian Revival, but when i read on the maker and style they use most of the time, make more sense to call it Celtic, definitely as a Celtic look after all, and the glass stones(7) that compose this brooch are just outstanding in my opinion.
The brooch is very well made with lot of incised decoration in the Nickel plate base that surrounded each glass stones, mark at the top"Miracle"

The Brooch is 2 inches wide.
