Art Deco Diamond and Onyx Ring in Gold and Platinum, circa 1930

Dating from around 1930, this Art Deco ring plays with the striking contrast between sparkling diamonds and deep black onyx. Its distinctive geometric design is softened by the warmth of the yellow gold band, while platinum lends a cool brightness to the upper section. Small yet full of character, it captures the glamour and confident elegance of the Art Deco age.
