    For a long time (and maybe still currently I don’t know) they weren’t able to make diamonds bigger like people want. So for a small diamond it might not make any sense, but there was a point where ones we made weren’t meeting what people wanted.

      synthetic diamond sizes keep getting bigger, but it is much harder to make them I think

      As of 2023 the heaviest synthetic diamond ever made weighs 30.18 ct (6.0 g); the heaviest natural diamond ever found weighs 3167 ct (633.4 g). Wikipedia

      That would be 1.7 vs 181 cm3
