Questions About 1 Carat Demantoid
  • 1stDibs ExpertNovember 27, 2023
    Whether 1-carat studs are too big depends on your personal preferences. Stud earrings with a total weight of 1 carat will usually each feature a 0.5-carat gemstone, which is often the medium-sized offering from jewelry makers. At this size, studs will sit nicely on the earlobe without completely covering it. On 1stDibs, find a wide range of gemstone stud earrings.
  • 1stDibs ExpertJanuary 23, 2024
    Whether a 1-carat earring is too big depends on your personal preferences. An individual earring with a 1-carat stone will usually cover a good portion of the earlobe without completely hiding it. As you shop for studs, keep in mind that there is a difference between total carat weight and carat weight. The carat weight refers to the weight of each earring, while the total carat weight is the combined weight of both earrings in a pair. A 1-carat earring set would actually typically include two 0.5-carat earrings, which are generally small enough to keep most of the earlobe visible. On 1stDibs, explore a large selection of gemstone earrings.

    How much a 1-carat blue diamond is worth depends on its cut, clarity and color. Human-made synthetic blue diamonds of that size are often worth less than $10,000, while natural examples sourced through mining are generally valued at much higher prices.

Because so many variables can impact the potential value of a blue diamond, experts generally recommend having a certified appraiser or experienced jeweler assist with the valuation process.
