Here is a really unique mineral specimen oddity from Utah. It is difficult to fully appreciate this specimen in a 2D photograph because it is so 3-dimensional in person, but it's something quite eye-catching an unusual. What we have is what appears to be a wavy, cloth-like sheet of black goethite that has white calcite accenting it. The theory is that this goethite was once covering some other mineral, and then it sloughed off in a slow-motion melting-like process to form this crazy sheet of material. One of a kind for sure!
Condition is excellent. A previous owner used silicone to attach this to a base, so there is still some silicone residue on the very bottom of the specimen. Could probably be removed with a long soak in acetone, but it really doesn't affect the piece since you don't notice it at all as most is covered by the new base mount.
The specimen comes with a labeled acrylic display base.
