Large enamel button, probably “studio enamel” - flower shape filled with turquoise enamel shading to white enamel in the centre with a red exotic flower - or a red heart and gold candles or flowers. (I am not quite sure which way up the button should go). Back looks like silver but unmarked and untested so sold as white metal. Loop shank.

Size 1.3” (3.3 cm) across
