An instrument designed to estimate the mass of a gemstone, usually in carats, based mostly on its dimensions. As an example, a cubic zirconia reduce to the precise dimensions of a one-carat diamond will usually register as roughly the identical carat weight when calculated, though the precise mass will differ as a result of density variations.
Exactly estimating a gemstone’s mass is essential in valuation, buying and selling, and jewellery design. Traditionally, estimations relied closely on expertise and visible evaluation. Using dimension-based calculations supplies a extra goal and repeatable evaluation, lowering discrepancies and aiding in honest pricing practices. This technique is especially helpful when direct weighing will not be possible or when coping with mounted stones.
