Dresden rose, made in Germany, these are new old stock, white enamel over guilloche patterned brass with silver plating, slightly dapt. Hand painted pink cameo topped with clear hard glass enamel to finish protect the painting, just the way they did it back in the day. A wonderful 25x18mm size, great for setting just as you would a cameo. It's been a long while since I have had any stock in the old dresdens, they are so lovely....grab some for yourself and hoard them. Vintage, old jewelry parts. Sold by the piece while they last.
