Mount Shasta Nebula Opal at its finest. This is a high-quality Mount Shasta Opal that we call Nebula. We call them Nebula because they remind me of a space Nebula. The Nebula Opals are the rarest of the Mount Shasta Opals we have. There is lots of orange coloring that comes from Manganese. This beauty measures 3 1/8 inches by 2 7/8 inches by 1 inch. This is a solid piece of Mount Shasta Opal. This would make a great addition to anyone's collection.
