What are the Different Grades of Pearl?

  • Pearl Grading

    When buying pearl jewelry, it’s important to understand the grading system used to evaluate pearls. Pearl grading is based on several factors, including size, shape, luster, surface quality, and color.


    The size of a pearl is measured in millimeters. Pearls that are larger than 10mm are considered large, while pearls that are smaller than 7mm are considered small. This also has to do with the type of pearl.


    Pearls come in a variety of shapes, including round, drop, oval, button, and baroque. Round pearls are the most valuable and sought-after, while baroque are have a random shape. Their prices are determined by there rarity in the market.


    Luster refers to the brightness and reflection of a pearl’s surface. Pearls with high luster have a bright, mirror-like surface, while pearls with low luster have a dull, matte surface. This is often referred to A, AA, AAA luster.

    Surface Quality

    The surface quality of a pearl refers to the number and size of blemishes on the pearl’s surface. Pearls with high surface quality have few or no blemishes, while pearls with low surface quality have many blemishes. It is important to remember that these are natural imperfections.


    Pearls come in a variety of colors, including white, cream, pink, gold, and black. The color is determined by the type of oyster the pearl grows in. Japanese Akoya pearls are usually white, or silver-blue. South sea pearls can come in white or gold. Tahitian pearls are also known as black pearls, and range in color from silver to jet black. Freshwater pearls come in an array of pastel colors.
