How To Understand The HCA Score

Output from the tool renders a 0-10 score, with lower scores indicating better cut quality. He indicates that a score below 2 eliminates more than 95% of all diamonds. The general guidance is that diamonds scoring between 0-2 are well worth further consideration, while those scoring 2-4 are worth considering “only if the price is right”. Diamonds scoring 5 and below should be considered “only if price is your main criterion”, and those scoring at the bottom, such as very shallow stones with the fish eye effect, should probably not be considered at all.
Somewhat confusing to many users is the statement indicating that diamonds in the 0-2 range should all be considered equally; ‘a diamond with a score of .5 may not be better than one with a score of 1.5.’ This is a recognition that certain variances in a diamond’s proportions, within the top range, involve trade-offs in individual optical characteristics such as brightness and fire. Differences at this level fall more into the realm of personal preference than objective quality.
