At 9.5-10.5mm, these cultured freshwater pearls sit at the larger end of the freshwater size spectrum — and in black, that size carries real authority. The deep, dark body color is achieved through dyeing, resulting in a rich, consistent tone with the subtle surface complexity that genuine pearl nacre provides. Black freshwater pearls at this scale are a smart value play, delivering the visual drama of darker pearls at a significantly more accessible price point. The near-round shape preserves the natural character of the pearl while coming close to the visual impact of a perfectly round stone. Rhodium over sterling silver keeps the clasp clean, tarnish-resistant, and complementary to the cool depth of the pearl. At 18 inches, this necklace sits at a classic length that works at the collarbone on most necklines. This is a statement necklace that earns its place in a serious jewelry wardrobe. Specifications: Metal: rhodium over sterling silver. Stone: black cultured freshwater pearl, 9.5-10.5mm, near-round, dyed. Closure: spring ring clasp. Length: 18". Approx. 3/8" W.

Note that the black color in freshwater pearls is achieved through dyeing, while Tahitian pearls are naturally dark.
