24" Handmade Sterling Silver Link Chain Necklace

I love the chain it's beautiful but I texted a guestion about its authenticity for instance my jewelry repair man down the street could have made the very same chain but I asked for certificate of authenticity that a real Navaho jeweler made this chain and my response was that the Indian jewelry maker could not sign this certain product but can definitely send a certificate of authenticity from her but all I received was a receipt..like I said beautiful chain but for the price I paid I just wanted to have some kind of proof on who the maker really is, nice product but unhappy with company response.
