Pearls are typically assigned to four categories in the sorting process: Round/Semi-Round, Drop, Baroque, and Circle Baroque.
Round pearls are the most valuable and often most desirable of all pearl shapes. Semi-round pearls are virtually round, and will appear round when strung on a necklace or bracelet.
Baroque pearls are irregular in shape and at times elongated. Many people love the unique "character" of these pearls. These pearls are frequently found in designer and one-of-a-kind jewelry pieces.
Drop pearls are symmetrically elongated pearls that typically take the shape of a tear-drop. These pearls are truly unique and are very valuable when a pearl has that perfect "tear" or "pear" shape.
Circle-Baroque pearls are easily distinguished by their unique rings surrounding the pearl. This shape is most commonly found in South Sea pearls including Tahitian, Golden, and White South Sea.
