This is one SERIOUSLY AMAZING OPAL! It is a natural Australian Boulder Opal, and it is HUGE and has the most amazing array of colours going through it - to the point where it needs a name like Mermaids Tail. It overall has a dark lilac colouring, then in the light, you will see beautiful flecks of literally every single colour of the rainbow. If you are a lover of pastel purple and rainbows, this ring is definitely for you. Handmade into a Sterling Silver bezel set ring.
