What does Art Deco ring mean?

The term Art Deco ring means a ring produced in the Art Deco style. Most Art Deco jewelry dates back to the 1920s and 30s and features defined lines and geometric motifs. While a lot of Art Deco rings were black and white — the black coming from the use of onyx or black enamel and the white from rock crystal and diamonds — there is plenty of color in jewelry of the era. A perfect accent to diamonds in platinum settings were blue sapphires, emeralds and rubies, and these stones were also used in combination with each other.
