Pearl – Natural, Rough, Black

Different lighting can reveal the body color and orient of a pearl. Flash was used in the top photo of these cultured black pearls, while the bottom photo was taken without flash in fluorescent light. Bottom photo was edited somewhat to increase saturation, but the rainbow orient was present in the unedited image. Photo by James St. John. Licensed under CC By 2.0.
