When backlit by sunlight, these love hearts come alive with beautiful colours across the whole colour palette.  The hearts are made using solid copper wire, semi-precious gem stones and glass, which are then given a patina bath to darken the raw copper.  The next step is to use a special metal polishing cloth to reveal some of the bright copper highlights again, and finally the finished piece is set with a lovely glossy varnish.  Read over the patina copper process in detail in our 'the story of copper' blog post.
