Heart and sodalite necklace

I made this pendant a while ago as a school project. Before I went home to Norway, I started creating a new chain of sodalite gems as a gift for my Mum.
Unfortunately, I soon saw that the cord was not strong enough, so took it back to the workshop for some extra work.

Instead of threading the cord through the jump rings on the back of the pendant, I have made it possible to disconnect the cord from both sides of the pendant. It is now easy to clean it and it can also be changed to a standard silver chain if wanted.
