Questions About Half Carat Diamond Value
  • 1stDibs ExpertSeptember 28, 2021
    The minimum value of a 25-carat diamond ranges from $300 to $1,400. The prices change subject to the fluctuation of market factors. The value is defined based on the 4Cs — color, clarity, cut and carat weight. Shop antique, vintage and new diamond jewelry 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.
