This copper cuff is formed from .7 mm copper sheet.

The sheet has been heated and folded.  The folds are hammered to set the creases.

The sizes and folds in these pendants are unique to each pieces.  Some are rectangular and others squares.  The folds vary from parallel to crossed.

The beautiful colour on the copper is a result of the heating process.  As a result each piece will have a unique colouring.
