This is a polished oval-cut ammonite fossil, showcasing the most striking spiral. Generally, ammonite fossils are either displayed as they are or, in some cases, made into beads or pendants by drilling holes through them. This results in a rough texture, and gives the impression of forcing a creature into an accessory. This particular piece, however, has been polished to remove that fossil-like quality, highlighting the beauty of the spiral, often referred to as the golden ratio. The spiral structure of the ammonite, resembling a series of chambers, is a result of the pursuit of functionality for survival. Therefore, polishing it into a form, like a loose stone, that is easier for us humans to appreciate can be considered a form of functional beauty. I don't believe that everyone will appreciate the polishing, but the beauty is undeniable. If you'd like to enjoy this spiral structure, please consider it.
