I really never considered purchasing boulder opal before. That is, until my friend Patty told me how beautiful it is. So, I took a close look and she's right! It has wonderfully rich coloration and lots of lovely matrix and inclusions. I've taken some photos in my hotel room, which explains the poor quality.
And just for fun, here's a photo of the HUGE amethyst brios mentioned in my previous post. Stop drooling Brenda!
