In the current market, there are mainly ten types of shapes that rough diamonds are polished into.
Naturally, some have become more popular over the years due to changes in consumer tastes and fashion. Without a doubt, the top seller among the shapes is the round brilliant cut. When cut to ideal proportions, round diamonds offer the best sparkle and light performance compared to any other types of shapes.
Coming in at 2nd place based on popularity is the cushion cut, cushion cut diamonds had overtaken princess cuts with a recent surge in demand. On the other hand, shapes like the triangle cut are considered as rarities and seldom seen in the consumer market, they might still appeal to people looking for exquisite choices.
