Mostly pearls are not perfect round in shape, so the round shaped are more expensive. Always look at the pearls holding against a neutral background. Examine the pearls surface under daylight or fluorescent light. If possible, you should examine all the pearls at same time in the day at the same location. Pearls may look different when examined under some other type of light.

Use your naked eye for examining the pearls for scratches, pits or discoloration. Check the pearls for luster. Good pearls look shiny and appear as if lit from inside. They reflect light better as compared to flawed pearls.

Study the orient of pearl. The orient means the colored glow on the surface of the pearl. Check the color of the pearl. Pearls having their natural color tend to be more expensive than the dyed pearls. The overtone of the pearl is either warm pink or a cool blue.
