Impressive 5,370ct split Ammonite fossil with Ammolite Opal

This large fossil was professionally cut and exhibits a beautiful fibonacci sequence with well defined chambers filled with druzy crystals and shifts to chaotic chambers that flow together and everywhere at once. The outer shell displays vibrant red and violet ammolite opal, and you can observe the crisp flaired maple leaf patterned sutures peaking out from behind the opal development. This piece has amazing size, measuring approximately 182.5mm x 148.1mm x 39.5mm (when together) and weighing over two pounds! And it comes with display stands!
