Questions About Antique Tiara Ring
  • 1stDibs ExpertNovember 2, 2023
    Yes, some antique rings have hallmarks. However, some do not. Before 1950, jewelry makers didn't add hallmarks to their pieces, but some did to indicate who produced the jewelry and/or tell the buyer what type of metals they contained. Shop a large collection of antique rings on 1stDibs.
  • 1stDibs ExpertNovember 1, 2023
    Antique rings were made of a variety of materials. You can find pieces produced out of many of the same precious metals used today, such as yellow gold, white gold, sterling silver and platinum. In addition, some antique rings feature a material called pinchbeck, which is a combination of copper and zinc. On 1stDibs, explore a diverse assortment of antique rings.
  • 1stDibs ExpertNovember 21, 2023
    Yes, antique engagement rings do tend to be popular. They especially appeal to brides-to-be who want something unique and like the idea of owning a ring that has a long history.

  • 1stDibs ExpertNovember 1, 2023
    The difference between vintage and antique engagement rings is age. For an engagement ring to be considered an antique, it must be at least 100 years old. Vintage engagement rings are pieces made at least 20 years ago. Shop a collection of vintage and antique engagement rings on 1stDibs.
  • 1stDibs ExpertJanuary 23, 2024
    The difference between vintage, antique and estate engagement rings comes down to age and history. Rings that are over 100 years old are antiques, while those produced 20 to 99 years ago are vintage. Estate engagement rings are any rings that have had a previous owner. They can include antique, vintage and even contemporary rings produced during the last 20 years. Shop a large selection of engagement rings on 1stDibs.
