You can distinguish between real Tiffany and Co. bracelets and fakes by inspecting the engraving, smoothness of the links, the material it's made of and its length, according to FashionAccessoryForum.com.
According to FashionAccessoryForum.com, Tiffany and Co. bracelets are made with links, which aren't quite round but are more oval. In addition, the links never pinch; however, they're sealed together to appear smooth.
The lobster clasps on all Tiffany and Co. bracelets are stamped with the numbers 925, according to FashionAccessoryForum.com. Some of the pieces even include signatures along with the 925 stamp.
Material and Length
Tiffany and Co. bracelets are created from .925 sterling silver, with a length of 7 1/2 inches.
According to FashionAccessoryForum.com, the Tiffany and Co. bracelet has an engraving that says, "Please return to Tiffany." This engraving is easy to see and read, because it's clear, not blurry.
