Baroque pearls are pearls with an irregular, non-spherical shape. [ 1 ] [ 2 ] Shapes can range from minor aberrations to distinctly ovoid, curved, pinched, or lumpy shapes. Most cultured freshwater pearls are baroque because freshwater pearls are mantle-tissue nucleated instead of bead nucleated.
The English word pearl comes from the French perle, originally from the Latin perna ' leg ', after the ham- or mutton leg-shaped bivalve. [5] The scientific name for the family of pearl-bearing oysters, Margaritiferidae comes from the Old Persian word for pearl *margārīta-which is the source of the English name Margaret. [6] [7] [8]
The word baroque was also associated with irregular pearls before the 18th century. The French baroque and Portuguese barroco were terms often associated with jewelry. An example from 1531 uses the term to describe pearls in an inventory of Charles V of France 's treasures. [ 9 ]
A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as a conulariid.Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) [1] in minute crystalline form, which has been deposited in concentric layers.
The cultured pearls on the market today can be divided into two categories. The first category covers the beaded cultured pearls, including Akoya, South Sea, Tahiti, and the large, modern freshwater pearl, the Edison pearl.

[3] The cultured Tahitian pearl comes in various shapes, sizes, and colors; shapes include round, semi-round, button, circle, oval, teardrop, semi-baroque and baroque. [4] Because of their darker hues, Tahitian pearls are commonly known as "black pearls". [5]

Assorted keshi pearls. Keshi pearls are small non-nucleated pearls typically formed as by-products of pearl cultivation. A Japanese word also meaning "poppy" (ケシ, 芥子), it is used in Japanese for all pearls that grew without a nucleus. Originally, keshi pearls referred to those pearls formed when a bead nucleus was rejected.
