I inherited a 1924 pearl necklace from Niagra Falls. My great-grandparents came from Canada and went back in 1924 for a visit. They purchased the necklace for my grandmother. The story about the trip is in our family geneology book as well as a photo of them at Niagra. After Grandma passed away my oldest sister inherited the necklace which she then gave to me. The necklace is in it's original box. I am interested in selling the necklace as I don't wear jewelery and do not have children to pass onto. Is the necklace of any value? Should I have it appraised? Thank you.
