Why are round pearls generally more valuable than other shapes?

Round pearls are generally more valuable than other shapes primarily because their production is more challenging. The formation of round pearls requires specific conditions and influences, such as the quality of the oyster or mollusk, the type of irritant that results in pearl formation, and the environment in which they are cultivated. As a result, achieving a perfectly round shape is much rarer than other shapes like baroque or drop pearls.

The round shape is often considered the most aesthetically pleasing and desirable for jewelry, which further increases their value in the market. Additionally, because round pearls demand greater care and precision during the cultivation process, there is a limited supply of high-quality round pearls, which contributes to their higher valuation compared to other shapes that may be produced more easily or in greater quantities. Thus, the challenges associated with cultivating round pearls in the context of desirability make them a sought-after choice in the world of pearls.
