This Victorian 10k solid gold brooch contains a spring loaded mechanism and was patented in 1872. When the end balls are depressed, a spring inside would move a pin in the two shorter tubes. This probably clipped in the ends of a necklace chain so that the brooch could be worn as a pendant. The dove is three dimensional and quite detailed. It holds an olive branch in its beak, a symbol of peace. Note that the branch is green gold, which contrasts with the pink gold of the brooch. There is meticulous hand engraving and black tracery enamel to each side of the bird. The piece is 2 1/2" long and 1" wide, tested as 10k solid gold and weighs 10.5 grams. It could be worn as a pendant if a jump ring were to be attached to the small ring in the center, under the bird's head. It would look superb on a sweater or lapel. or on the knot of a scarf. If you are interested, I could ask my jeweler about converting a chain for its original purpose.
