PRACTICAL COMPARISON
Two quotations.
One clearer view.
Enter your own figures to compare diamond price per carat and total quoted cost.
Use the same currency for both quotations. This tool compares arithmetic, not diamond quality or market value. It has no live price feed.
Formula: price per carat = diamond price ÷ carat weight. Total = diamond price + other quoted costs. Inputs are processed in your browser and are not stored or submitted.
Numbers are only the beginning.
Compare the experience
Consider appearance, setting, inspection, aftercare and written seller terms.
