Antique early 1800s French opaline mustard pot, perhaps usable as a salt pot or service piece. White opaline glass mounted as a bee's nest service piece (probably would have had a small service spoon fitted on that pin you see). The beehive formation is indicative of the Napoleon I era, and the type ormolu and alabaster base with the opaline would have identified it as having come, most likely, from the boutiques of the old Palais Royal. Formerly the Palace of Cardinal Richelieu, it became a center for elite commerce, entertainment, and the famed boutiques that lined the interior promenade of the gardens remain of exceptional interest and value today. You might choose to use it at table for toothpicks, matches, or mustard, jam - or just to display this charming antique in your collection.
Very good to excellent condition for age and type. Alabaster base is the old original, of course, and no damage to it, the ormolu, nor the cylinder of fine French opaline glass. Possibly would have also had a small spoon or laden to hang from the little piece of ormolu (pin) you see at the upper rim. Nicely crafted. An early 1800s item.
