I am looking for an old genuine tortoise (hawksbill) chain necklace. This item is typically a Victorian to Art Nouveau time period and must not be faux tortoise shell but the real thing. I do not want something modern as making new jewelry from this material is very illegal. I am looking to repair a necklace that is missing pieces but is very ornate and if i get the right chain it could again be museum quality. Any condition is fine even broken will still work.
