Diamonds ranging from 5 to 10 carats have a distinct advantage over diamonds in the 0.5 to 2 carat range: it is easier to notice the differences in their optical performance and variations in proportions, which are important factors for quality cutting. Larger diamonds typically allow for better visibility of these distinctions compared to their smaller counterparts, thus attracting consumer interest in diamonds with superior cuts. However, to what extent consumers would be interested in LGD (lab-grown diamonds) measuring 50 carats or 100 carats remains a question.
