Triple Cherub EI Brooch

Brushed gold brooch with three cherubs on a black enamel background with an ornate surround. This is one of my favorite pieces of jewelry. High Quality Costume. It was purchased in the early 2000's and I really don't know how old it was at that time. Unknown metal. Has not turned color in any area. I have always stored it in a velvet lined jewelry drawer. Stamped EI.
