This is a French art glass scent perfume bottle (or cologne) that is a chatelaine, with a chain that hangs on another chain around the neck or from a purse or belt, purchased by a young lady during the Grand Tour. The glass is green opaline, sometimes confused with jade glass. The date is circa 1860.
These perfume bottles do pop up from the estates, and the glass is always opaline; white, green or blue.
The bottle is 2 ½” long. There is no clear crystal tiny stopper under the lid, which there would have been originally, but these stoppers go missing easily and far in the past.
The metal is bronze, maybe brass, but I think bronze. The lid snaps on firmly. The filigree bronze metal around the glass shows a pair of lovebirds on each side of the bottle, touching beaks against a background of leaves and scrolls.
The glass has no nicks, chips or cracks. The metal shows age patina, but no other wear is obvious.
