This is one seriously epic solid Australian Boulder Opal!! I could write so much but honestly this one clearly speaks for itself. Not only does it have amazing colours and patterns, but there are TWO totally different worlds going on within this beauty!! The purple/lilac side is super soft and really pops in sunlight, which is when you'll see amazing pastel rainbow colours in stripes, the whole way through it. The blue green side of the Opal is just super amazing and bright no matter what lighting, and where they meet is just as beautiful as either side.
