Check out this incredible ammonite! It's perfectly preserved and has a mesmerizing iridescence that’ll leave you in awe. The rainbow colors come from how light interacts with the tiny structure of the fossilized shell, creating the nacre or mother-of-pearl layer. It’s similar to the iridescence you see in modern oyster and abalone shells. These 1” thick polished blocks are made from a special casting method that makes them super clear, deep, and realistic. The image in the print is created by an artist using the Giclee process and has been enlarged for an amazing viewing experience. It’s the perfect addition to any shelf, desk, or table!
