Red Fire Iridescent Cleoniceras Ammonite from the...

Red Opal Iridescent — A specimen of a fossil ammonite of the genus Cleoniceras, from the famous Cretaceous Malagasy deposits. This piece is not only a palaeontological testimony of extraordinary preservation but also a work of rare natural beauty, thanks to its polished surface that reveals spectacular iridescences. The shell has been skillfully sectioned to expose its complex internal structure and accentuate the color play that makes it a unique piece. The logarithmic spiral shape, perfectly preserved, is the iconic symbol of these ancient cephalopods. The surface, mirror-polished, enhances a rich range of warm colors, ranging from tobacco brown to translucent caramel. It is along the sutural lines—the intricate partitions that separated the shell’s inner chambers—that the true magic of this fossil manifests. Here, the interference of light on the original aragonite layer, preserved by the fossilization process, produces an intense opalescence with fiery red dominants and orange flashes that dance and change with the viewing angle. This magnificent specimen began its existence about 110 million years ago, navigating the oceans of the Late Jurassic (Early Cretaceous). After the organism's death, its shell settled on the sea floor and, under favorable environmental conditions, was covered by sediments. The fossilization process mineralized the structure, replacing organic tissues with minerals such as calcite. In Malagasy deposits, a layer of the original mother-of-pearl (aragonite) has often been preserved, giving rise to the iridescence phenomenon, structurally similar to that of the precious organic gem Ammolite. Beyond its undeniable scientific value, this fossil is a highly prized collectible piece and a decorative element with strong visual impact. Its natural elegance and chromatic vibrancy make it a perfect candidate for a contemporary Wunderkammer, a library, or as a focal point in a study. The specimen tells a story of eons, uniting the geometric perfection of nature with an explosion of color that seems almost alive. The preparation through partial cutting and careful polishing transforms an ancient find into a natural sculpture, one that captures light and the imagination of those who observe it.”} ) } Wait there is extra characters at end; ensure JSON proper.
