ID this light please..has a heart shaped stone on inside of shade trademark?

I found this at my local thrift store...It has a heart shaped cabochon soldered to the underside of the shade which i assume is some kind of a maker's mark..does anyone have a clue who made this? It has a three light fixture...it does say Forecast Lighting company on the metal ceiling plate., but didnt know if that was just for the plate..Am hoping to determine the age of it...
