Does it have a lot of color when you move it ? is there any red ? I have several opals and red is the hardest color to find in an opal. Blues & greens are more common & they are beautiful. I just need one for a friend and she likes the ones w/ red in them.. The color in all opals is referred to as the fire. but Fire opals are orange. based not white.. There the only ones I'm aware of that are actually called Mexican fire opals. I have a couple and one is actually all orange, its still a Mexican fire opal. Very pretty , will make a great gift. Thank you for letting me put my 2 cents in. Legends Gramma
