Dance chatelaine on a stick brooch with a chestnut-shaped scent bottle

Dance chatelaine on a stick brooch with alternate rings in gold and burnished silver, probably a mourning jewels. The alternance of the two colour characterized all the four attached items in different ways: a metal scent bottle, shaped as an open chestnut with a hinged perforated cap, an aide-memoire with ornate cover, a retractile pencil and a little round box for pills or make up.
