A striking Art Deco period amethyst riviere necklace with matching earrings, dating from the 1930s–1940s. The necklace is set with a continuous graduating line of richly coloured oval amethysts, each in an open-backed mount that allows maximum light to pass through the stones. The suite includes matching clip-on earrings, completing the original period set. With its bold purple hue, substantial weight, and classic Art Deco craftsmanship, this is a rare and highly collectable gemstone suite.
