Huge purple boulder opal, 21.20ct

Sometimes struggle is real and I spent ungodly amount of time to try and catch the purple this incredible boulder opal shows and after two days of chase I'm still not sure it's even close.

This is a fantastic large boulder opal where each stripe shows different patterns - with Purple dominating, and some blue, as well some green sparkles in direct sunlight.
