Genuine citrine early Victorian brooch, gold filled, crimped stone setting

Here is an early Victorian brooch with a genuine citrine stone set into the middle (tested on a Presidium Gem Tester). This stone also looks like it might have a foil back as there is some black speckling visible (a sign the foil has eroded over time). The stone has a crimped setting, a sign of an earlier 19th century piece. There is a dangle with a small pearl in it. The metal is gold filled. The back: I have not been able to remove the glass. It has a later picture in there that looks to be from the 1940s of a woman. If you want to switch the picture you may have to take this to a jeweler as I have not been able to pop the glass out. Please be aware the pin extends quite a bit beyond the brooch, typical of antique jewelery, but take care not to stick yourself with it! Brooch measures 1 7/8" x 1". Good condition with some tarnish. The stone is secure and the pin on the back is in good working order.
