What does the term 'process' refer to in cultured pearl preparation?

The term 'process' in cultured pearl preparation refers to a procedure that involves cleaning, buffing, and sometimes bleaching the pearls. This step is crucial to enhance their appearance and ensure they meet the quality standards expected by consumers. After the pearls are harvested, they undergo this process to remove any surface blemishes and enhance their luster, which is essential for the final product to be visually appealing.

While other options refer to different aspects of pearl treatment and cultivation, they do not define the term 'process' in the specific context of preparing cultured pearls for market. Cleaning and buffing improve the physical attributes of the pearls, while bleaching, when necessary, addresses color inconsistencies and can enhance overall brightness, thereby improving the pearls' attractiveness.
