Art nouveau egyptian revival scarab beetle insect brooch

  
Drop dead gorgeous art nouveau Egyptian revival scarab beetle brooch dating from the 1800's. It features a real scarab beetle set upon a white metal dragonfly winged brooch. Totally iconic for it's era. When I received it, it was filthy. I have given it a light clean but it is still in need of further cleaning, which I think would be best done by a more proffesional person, due to the delicate nature of the brooch.
