welcome, cheface99,
Please give us some additional photos. A close up of the clasp and description of any markings there. What size, at least approximately, are the pearls? We need some close up pics of a section of the pearls and photo of whole necklace. Also a photo of any blemishes on the pearls. Is the strand knotted? It doesn't appear to be from your photo. Please photograph the pearls against a white paper towel or something similar, as it helps us to evaluate the luster. I haven't seen a wooden box before, interesting.
