Pearls that exhibit noticeable surface characteristics are classified as what?

The classification of pearls that exhibit noticeable surface characteristics typically falls under a category where the surface is not entirely smooth but has some degree of blemishing. Pearls that are described as "moderately spotted" acknowledge these visible surface imperfections without being overly pronounced. This classification is essential in pearl grading and valuation, as it directly impacts the aesthetic appeal and market value of the gemstone.

Heavily spotted pearls would indicate a greater extent of surface marks, potentially placing them in a lower quality category. Uniformly smooth pearls, on the other hand, would suggest a high quality with minimal to no surface imperfections, which is not the case for pearls with noticeable characteristics. Perfectly flawless pearls represent the highest grade and would be devoid of any noticeable blemishes, categorically different from those that exhibit visible surface traits.
