  The shape of a pearl is defined by degrees of roundness, symmetry, and irregularity. Shape is an important characteristic in determining the value of a pearl, and pearl shapes are generally categorized as Spherical, Symmetrical, or Baroque. Spherical, or round, pearls are usually the most valuable, especially if they are part of a well-matched piece.
