Chiapas Fossil Amber – Specimen with Iridescent Colors - High Quality Mexican Amber - Height: 86 mm - Width: 72 mm- 138 g - (1)

Mexican Fossil Amber — This splendid specimen of Mexican fossil amber comes from the Simojovel region, in the state of Chiapas (Mexico), an geologically exceptional area for the formation of transparent and polychrome ambers dating back to the Early Miocene. Polished and carefully finished, the surface reveals an extraordinary internal complexity made of plant inclusions, natural pigments, and iridescent zones that respond to oblique light or UV. Scientific and Geologic Data Name: Chiapas Amber Geologic Origin: Mazantic Shale Formation Locality: Simojovel de Allende, Chiapas, Mexico Age: Early Miocene, about 22-26 million years Formation environment: Ancient tropical subtropical forest, similar to today’s humid Central American forests Resin-producing tree: Hymenaea mexicana (extinct species of the Fabaceae family) Chemical composition: Polymers of organic terpenoid compounds, approximate formula C₁₀H₁₆O Fossilization: Slow polymerization in an oxygen-poor environment, which allowed the preservation of internal structures, inclusions, and chromatisms Characteristics of the Specimen Dominant color: Amber-red with transparent zones and golden and orange reflections Optical effect: Three-dimensional internal luminosity, with flashes emerging from different depths In inclusion: Possible fragments of vegetal material or mineralized organic traces UV fluorescence: Strong (yellow-green), with possible blueish reactions Finish: Hand-polished and ground, irregular but harmonious shape Chiapas amber is among the most valued in the world for transparency, rarity, and the presence of fossil inclusions. It represents a natural archive that preserves ancient evidence of plant and animal life in tropical Cenozoic environments. This specimen, for its beauty and its peculiarities, is ideal for collectors, researchers, and natural history enthusiasts.
