two crystal drinks decanters with stoppers, made by different manufacturers, so they are not a matching set.
Square decanter
RCR — Royal Crystal Rock, Italy, confirmed by the label. Traditionally used for whisky or spirits, with a substantial base, diamond-and-fan decoration and rounded stopper.
Wide-bottomed decanter
Cristal d’Arques, France, confirmed by the label, which also specifies over 24% lead oxide. A wine or spirits decanter with a slender neck, geometric decoration and flat-topped stopper.
