Looking like it's right out of the Guardians of the Galaxy movie, this Opal concretion from Ethiopia resembles the orb hosting the Power Infinity Stone! This is just totally surreal and fascinating with its overall purply bronze color covered in patches of colorful orange, green and red. And then there's the surface texture which is amazing with its rounded, raised, polygonal pattern that adds to the intrigue and mystery of this wonderful Opal. It is likely quite gemmy inside, but the natural shape and colors of this complete and naturally formed nodule make me resistant to cut it open and see. Both sublime and futuristic...almost otherworldly! 255 grams. (In person, with strong lighting, you can see depths to the opal as well)
