How much is a 1-carat blue diamond worth?
1 Answer
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. If a gemstone is set in a piece of jewelry, it may have additional value due to the precious metals, the maker of the piece, its age and other factors. 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. On 1stDibs, explore a diverse assortment of blue diamond jewelry.
