925 sterling silver, Marcasite, Crystal & pearl necklace. I thought this was a Judith Jack necklace, but I do not see her signature anywhere on it. If it is hers, the pearls are most likely faux, I’m not sure. But this is a dainty necklace that can be worn with just about anything. Adjustable up to 2”. Measurements in pics. I would say this is vintage, probably from the 1990’s. Feel free to ask questions
