Questions

Diamond Weight Calculator FAQ

Can this calculator provide an exact carat weight for a purchased diamond?
No, it offers approximate estimates based on entered dimensions; official carat weight requires professional grading from a certified gemological laboratory.
What diamond shapes does the calculator support?
The tool handles twelve common shapes, including round, princess, cushion, emerald, heart, oval, marquise, pear, baguette, trillion, Asscher, and radiant cuts.
Do I need to know the diamond's measurements in a specific unit?
Users can input length, width, and depth in any consistent unit; the calculator will process the values and display the result in carats.
Is the weight calculation the same for all diamond shapes?
No, each shape uses a distinct geometric formula to estimate weight, accounting for facet patterns and proportions unique to that cut.
