An elegant matched pair of cut and polished ammonites from Madagascar, dating back to the Cretaceous period more than 65 million years ago. The polished faces reveal the classic spiral structure with beautifully defined suture lines and crystallized chambers, where deep black calcite contrasts with shimmering mineral inclusions. The natural balance between the glossy dark interior and the lighter mineral highlights creates a striking visual depth. Presented on clear acrylic stands, this pair combines both scientific interest and decorative refinement, making it a perfect choice for collectors, educational display, or interior decoration.
