Questions About Diamond Onyx 1920s
  • 1stDibs ExpertDecember 4, 2023
    What era 1920s jewelry is depends on its design. Most people associate this decade with the Art Deco movement, which took inspiration from eclectic sources like Cubism, ancient Egypt and Native American, African and Asian motifs. However, some pieces produced during the 1920s are more in line with the style trends of earlier periods, such as Art Nouveau, Edwardian and Victorian. Explore a diverse assortment of 1920s jewelry on 1stDibs.
  • 1stDibs ExpertApril 5, 2024
    The clothing style in the 1920s that most people think of first is the flapper style. Women who dressed in this style sported loose-fitting, short dresses, often outfitted with drop waists and fringe. Small cloche hats and headbands were signature accessories of the flapper look. During the decade, pleated tennis skirts and cardigan sweater sets left the courts and became staples of some women's everyday styles. For men, soft collars replaced stiff, starched ones, and simple single and double-button suit jackets worn without waistcoats became trendy. Trousers also took on a new shape with wider-cut legs, and Oxford bags gained popularity. On 1stDibs, shop a variety of 1920s apparel and accessories.
  • 1stDibs ExpertJune 15, 2023
    In the 1920s, fashionable colors included jewel tones. Fashion, jewelry, furniture and decorative objects often featured jade green, deep reds, amethyst purple, dusty mustard yellow and peacock blue. Find a range of 1920s-era jewelry and fashion on 1stDibs.
  • 1stDibs ExpertNovember 21, 2023
    In the 1920s, engagement rings still looked like rings but were representative of a diverse range of styles and influences. Art Deco diamond ring designs took inspiration from the contemporary Cubist movement as well as from ancient Egypt – a revival sparked by the opening of King Tut’s tomb in 1922. Native American, African and Asian motifs also inspired jewelry pieces. Diamonds in square and rectangular shapes incorporating angular steps – like emerald cuts, Asscher cuts and baguettes – were set against black onyx, rubies, sapphires and emeralds to create color-blocking effects. Platinum, 18-karat gold, 14-karat white gold and sterling silver were some of the favored metals of the decade. Find a wide range of Art Deco engagement rings on 1stDibs.
  • 1stDibs ExpertNovember 21, 2023
    In the 1950s, several diamond cuts were popular. They included the brilliant round cut, the Asscher cut, the emerald cut and the marquise cut. Rings that featured a large central stone flanked by smaller baguettes were also trendy during the decade. Find a collection of vintage diamond jewelry on 1stDibs.
  • 1stDibs ExpertNovember 6, 2023
    There were a few popular diamond cuts in the 1950s. One was the brilliant round cut, which is still common today due to its simple shape and prominent sparkle. Other favorite cuts of the decade included the Asscher cut, the emerald cut and the marquise cut. On 1stDibs, explore a large selection of engagement rings.
