Bangles are similar to bracelets but are a more rigid structure and can sometimes be worn higher on the arm. The most commonly worn bangle is the torque, but there are others like a Russian bangle which have three smaller bangles to make the whole piece, that are also easily recognisable.
There are still different metals to choose from silver, titanium and gold all with a great amount of design.  The designs are usually on a larger scale and use less stones.
