Sterling Silver Pendant Necklace

Someone with an allergy to nickel had a problem with the blue oval pendant necklace Tiffany wire?
I bought this pendant necklace (http://www.tiffany.com/shopping/Item.aspx?sku=18596474&mcat=&cid=288158&search_params=s+2-p+18-c+288158-r+101287465-x+-n+ 6-ri +-ni +0- t +) and took about two hours before getting a rash on my neck. I am allergic to nickel and I am convinced that the cable is not sterling silver, Tiffanys but insist that everything is the pound sterling. Has anyone else had problems? I bought the necklace in a Tiffany store and it is the thing real. Thank you very much! Siofra Ps I am not allergic to other .925 sterling silver jewelry, Tiffany jewelry or other …
This pendant is made of 0.925 pounds sterling … This is made up of: .925 sterling silver is the traditional rule of silver. It's called 925 because it is an alloy that is 925 pieces of silver of a thousand. It allows the other 75 pieces other metals (usually copper) to increase its strength, because pure silver is very soft and is not structurally strong enough for many jewelry applications. 925 Sterling Silver has the glow of silver and the durability for everyday use. So … I could have traces of what you are allergic to because it is not pure silver. I hope this will help.
