Luster

Pearls all have a deep inner glow and beautiful shine, which is known as luster. This effect is produced from light reflecting off abundant layers of calcium carbonate crystals, also known as nacre. The higher a pearl's luster, the more valuable it is.

Shape

Pearls are divided into five shape categories, round being the traditional favorite. Shape is determined mainly by the nucleus form that the pearl is structured around.

  • Round: Symmetrically shaped spheres -- the most traditional, popular, and rarest shape.
  • Semi-round: Spherical form with slight variations.
  • Baroque: Irregularly shaped
  • Semi-baroque: Drop, button, oval, pear shaped -- partially symmetrical.
  • Circular: Irregularities on the upper third of the pearl such as streaks, ridges, or rings -- mainly Tahitian and South Sea varieties.

Surface Markings

During formation, blemishes such as bubbles and spots can appear when nacre does not adhere smoothly to the surface of the pearl, which is completely normal. The most rare and sought-after pearls have few imperfections and high-quality smoothness.

Pearl care, when done properly, is simple and can make them last a lifetime. Due to the natural body oils in the skin, wearing pearls as often as possible is a great way to keep their lustrous look.
