A very beautiful opal, Michael. I am a fan of precious Australian opal since childhood, this was one of the minerals that fascinated me from the beginning. And it took me long as a serious collector to find one I like AND I can afford. And that opal that became one of my most beloved pieces is like yours from the Quilpie area :-)
