Change Is Constant

I knew I wanted a use a stone for this piece and this stone is perfect! It is a colour changing obsidian. On the left, the obsidian is a pinky-brown in natural light, whereas under fluorescent light, it is quite green, as seen on the right!
For me, this stone aptly symbolises the transience of life: ever changing, never stagnant, surprises at every turn! While my 4 leaf clover is meant to bring good luck, luck also moves in cycles and is unpredictable! Change,truly, is the only constant!
