This lovely bracelet is composed of 7.5-8.0 mm off-round AA+ quality, color-treated, multi-hued black freshwater pearls. The colors are nicely blended, creating a peacock effect similar to the look of exotic Tahitian pearls. The pearls feature smooth surfaces and sharp, reflective luster. The pearls are knotted on black silk, and the bracelet is finished with a 14-karat fish hook clasp.As black is not a naturally occurring color in freshwater pearls, the pearls have been treated with a permanent organic dye to achieve their dark coloration. Blue overtones.
