Questions About Opal Baguette Diamonds
  • 1stDibs ExpertFebruary 22, 2021

  • 1stDibs ExpertApril 5, 2022
    Tapered baguette diamonds are diamonds featuring a baguette cut that angles narrower at one end. The baguette cut is long and thin, and features step-cut sides, though the corners are cut diagonally to create the tapered shape. Shop a collection of authentic tapered baguette diamonds from top sellers on 1stDibs.
  • 1stDibs ExpertNovember 14, 2023
    Baguette diamonds were especially popular during the 1920s and 1930s. You will commonly see diamonds cut into the rectangular stepped cut on Art Deco and Art Nouveau jewelry pieces. Contemporary jewelry may also feature baguette diamonds, especially those inspired by the style of early 20th-century rings, necklaces, earrings and brooches. On 1stDibs, shop an assortment of baguette diamond jewelry.
  • 1stDibs ExpertApril 5, 2022
    The term “diamond baguette” means small step-cut diamonds in a rectangular shape. Typically, jewelry designers use them as accent stones in engagement rings that feature square or rectangular center stones. You'll find a large collection of diamond gemstone jewelry on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    No, baguette diamonds are often less expensive than other diamond cuts. Since this diamond cut is less expensive than an emerald cut or brilliant cut, it is the perfect ring for someone on a budget who still wants the classic diamond look.
  • 1stDibs ExpertApril 5, 2022
    Yes, it is possible to diamond test baguettes. However, you should leave the work to a licensed jewelry appraiser in order to avoid damaging the jewelry and to ensure that the tests yield accurate results. On 1stDibs, shop a range of expertly vetted diamond gemstone jewelry.
  • 1stDibs ExpertFebruary 22, 2021
    Yes, baguette diamonds are real. Baguette diamonds are diamonds cut in a rectangular shape with 14 facets. The narrow, elongated shape of these diamonds make them the perfect accent stone.
  • The main differences of baguette cut diamonds and emerald cut diamonds are its shape and faceting. The shape of the baguette tends to be more elongated. The baguette also has 14 facets while the emerald has 58.
    1stDibs ExpertAugust 17, 2021
    The difference between baguette and emerald cut diamonds is their shape. While both a baguette cut and an emerald diamond are characterized by a rectangular shape and simple step cut facets, baguette cuts feature pointed corners while emerald cuts have wedge shaped polished corners.
