VINTAGE Damascene Bracelet, Earrings, Brooch-Spain

This is a beautiful vintage set of Damascene jewelry from Spain. My sister brought these back from her European travels in the 1970s and gave them to me. Beautiful bird and floral design. The bracelet has a safety chain on it. The earrings are studs , no backs. The brooch is a beautiful fan-shaped piece. There is a marking on the bracelet of IB or IG, I do not know whose maker Mark that is.? This is a stunning set.... looks awesome with a little black dress!
