The different types of pearl shape. **
*Freshwater once had a reputation of being small, wrinkled and blemished. These early pearls were known as ‘Rice Krispie’ pearls, and they dominated freshwater pearl production from the 1970s throughout the 1980s. Modern culturing technology and the introduction of the Hyriopsis cumingii pearl shell to replace the native Cristaria plicata has improved these pearls’ shapes by leaps and bounds. Today gem quality freshwater pearls can mimic fine saltwater pearls in shape and luster.
*Tahitian pearls come in a variety of shapes, the most valuable of which is round. Other shapes such as semi-round, drop, button, oval, semi-baroque, baroque and circle are also valuable and popular with jewelry designers.
*White South Sea pearls grow in an array of natural shapes. As with all other pearl types, perfectly round pearls are the most valued. Other more common shapes are symmetrical drop, button and free-form baroque, which can exhibit many beautiful variations in texture, luster and color.
