However in 1996, another natural abalone baroque pearl weighing 685 carats, discovered off the coast of California, and which is now in the personal collection of K. C. Bell, has replaced the "Big Pink Pearl" as the world's biggest natural abalone pearl, in the Guinness Book of World Records.
Having held the record for the world's largest natural abalone pearl, the appellation "Big" used for this rare natural pearl, discovered in the Pacific, off the coast of California, appears to be more than amply justified.
So is the name "Pink" which refers to the highly iridescent pink color of the abalone pearl that appears to have originated either in the pink abalone Haliotis corrugata, or the red abalone Haliotis rufescens, two species that can have a pink colored mother-of-pearl on the inner surface of their shells.
