Vogue Pearls

I was just given some pearls from my Grandfather that were my grandmothers who just passed away. She wore them up to 70 years ago but I am not sure if they are older than that. They are in a grey box that has "VOGUE" & underneath that word "London Paris New York" they are a double strand with an antique looking clasp. The only thing written on the clasp is "A Silver". Any idea if these are valuable please?
