Victorian Brooch

Hello I’ve just rediscovered this lovely Victorian Brooch which was one of my early finds, finding interesting things like this got me into going out looking for other interesting stuff that people had disposed of, I’ve always liked this but never gave it much thought, but I saw something similar on antiques roadshow and the expert was absolutely raving about it,also said it was unmarked but she could tell it was gold. This has no marks that I can see but looks handmade
