This is a loose stone created by cutting and polishing an ammonite fossil into an oval shape, highlighting the most striking spiral pattern. Ammonite fossils are often used as ornaments, or sometimes made into beads or pendants by drilling holes through them. These methods typically result in a rough, textured feel, giving the impression of a creature forced into an accessory. This loose stone, however, deliberately removes that fossil-like quality, focusing on the beauty of the spiral, often referred to as the golden ratio, through polishing. 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 loose stone, a form that is easily enjoyed by humans, can be considered a form of functional beauty. While I don't believe that polishing will appeal to everyone, the beauty is undeniable. If you'd like to enjoy this spiral structure, please consider it.
