When a stone is has a DQD, stating it is an ideal cut, With a zero in light performance, performance factors and finish, can the assumption be made that the stone will look good? it seems as it should? But It seems there are so many tools like the ASET, IS and HCAs data we need to consider. Do we only use these tools after we have looked at the DQD or can we skip thw DQD altogether and simply use the other tools.
