Identification of Two Kinds of Seawater Cultured Gray Pearls by Fourier Transform Infrared Spectroscopy and Ultraviolet-visible Absorption Spectroscopy

BACKGROUND Akoya pearl is a biomineralized organic gemstone. The mineral composition and microtextural analysis, and the identification method of color formation of this type of pearl are still lacking. OBJECTIVES To identify natural gray pearls from treated-color gray pearls. METHODS The spectrosco...
