This lot consists of a beautiful matched pair of genuine ammonite fossil slices from Madagascar, carefully cut and polished to reveal their intricate internal chamber structure. The spiral pattern displays natural crystalline formations within each chamber, creating a striking visual effect. Ammonites are extinct marine mollusks that lived between approximately 420 million and 65 million years ago. These specimens showcase the natural mineralization process, where the original shell has been replaced by minerals such as aragonite, sometimes producing subtle iridescence. The pair is well-matched, making it ideal for collectors, display, educational purposes, or even jewelry making. Each piece measures approximately 38 mm and weighs a total of around 27 grams. As natural fossils, slight imperfections, small chips, or variations in color and structure may be present, adding to their authenticity and uniqueness.
