How to choose a good-value cushion diamond
Compare the report, actual appearance and price together. We assess sourced stones as well as the diamonds on our own bench, and explain the trade-offs before you choose. Cushions cover different facet patterns and outlines. Compare the actual appearance rather than choosing on the grade sheet alone.
That is why the search marks stones we would not recommend, and offers you better ones at the same spec. We would rather lose a sale than sell you a stone we would not buy ourselves.
