From 1920 to 1930, the Art Deco era was marked by creative revolt, flapper trends, and a distinct aesthetic in jewelry creation. Following World War I, the Roaring Twenties were a period of transition. People wanted an escape from the consequences of the war, and women took advantage of this by changing their habits, dress, and jewelry. The reconsideration of jewelry designs, as well as engagement ring styles(it's now known as Great Gatsby vintage engagement ring from the 1920s.), was necessitated by a major shift in fashion style.
Cocktail parties grew fashionable in the 1920s, and cocktail rings and engagement rings became fashionable as well. Flappers of the Roaring Twenties developed a taste for jewelry that complimented their looks. You've seen the precise definition of Art Deco if you've seen The Great Gatsby. It depicted the 1920s modernist decorative style, which included everything from interior design to architecture, fashion, and jewelry.
After all, Gatsby is all about the glamour, so don't be afraid to go all out with the jewels that will truly make your day sparkle!
