Questions About Two And A Half Carat Diamond
  • 1stDibs ExpertFebruary 13, 2023
    Yes, a two-carat diamond is generally rarer than a smaller diamond, especially high-quality two-carat diamonds. When larger diamonds are found in nature, they usually have flaws. And prices per carat don’t increase as weight increases. A three-carat gem can be less valuable than a one-carat stone, for example, if all of the other attributes are of lesser quality in the larger diamond. Shop an assortment of diamond jewelry from some of the world’s top jewelers on 1stDibs.
  • 1stDibs ExpertNovember 27, 2023
    Whether half-carat diamond studs are too small is a matter of personal opinion. A pair of diamond studs with a total carat weight of 0.5 usually consists of two 0.25-carat earrings. Many jewelry makers offer studs as small as 0.13 carats, so many people consider half-carat diamond studs to be medium-sized. On 1stDibs, shop a collection of antique and vintage diamond stud earrings.
