Beautiful 17.75” high-end / HEAVY Cultured/Graduated Pearl Necklace w/sterling

Very high-end Graduated Cultured Pearl necklace! Contains 17.75” of lustrous, and quite heavy/solid, pearls with a sterling silver clasp of Victorian design, with an inlaid Pearl. No pearls are drastically discolored or coming loose. This strand is extremely strong!!! I’m reluctant to say because I can’t be sure, but these may be Mikimoto pearls. They did make a clasp almost identical to this one, and I’m certain of that. I am not certain that they are Mikimotos, but they are surely comparable in quality.
