A tool used to estimate the weight of a gemstone in carats based on its millimeter measurements. It provides an approximation of a gemstone’s carat weight using its dimensions, especially useful when the stone is already set or its weight is not directly available. For example, if a round brilliant cut diamond measures 6.5mm in diameter, this calculation tool can offer an estimated carat weight based on that measurement.
This method is valuable in appraising jewelry and verifying estimated carat weights provided by sellers. It offers a non-destructive way to gauge a stone’s size and potential value without removing it from its setting. Historically, jewelers have relied on visual estimations and experience, but these calculation tools provide a more objective and consistent measure, reducing the risk of inaccurate assessments.
