The dimensions of each diamond shape can impact its carat weight, which in turn affects our target carat weight range to maintain consistency and quality in our sustainably produced diamonds. Total carat weight refers to the combined weight of all diamonds in a piece of jewellery, and its tolerance can be determined by adding the minimum and maximum carat weights of the diamond sizes featured in the jewellery.
