ABSTRACT

The color of abalone pearls cultured in the Indian Ocean is bluish green, in the Pacific Ocean is greenish yellow, and in the Atlantic Ocean is greenish blue. Aragonite-like lamellar structures were observed in all pearls, with nacrethickness measured at 0.5~0.7µm. Ultraviolet-visible (UV-Vis) spectroscopy showed high reflectance at 475 nm, 500 nm, and 575 nm, corresponding to the colors of the abalone pearls. Additionally, X-ray diffraction (XRD) analysis confirmed the crystalline structure of aragonite. These results indicate that abalone pearls exhibit productivity, gemological characteristics, and material properties suitable for use as jewelry. If abalone pearls are produced and further developed in Korea (a country surrounded by three seas with a long history and advanced technology in abalone pearl cultivation) they could contribute to creating added value in the abalone aquaculture industry and fostering growth in the domestic jewelry sector.
