Ammonite Fossil Pair - with Rainbows
Ammonite Fossil Pair with good rainbow colours on exterior surfaces
140gm combined - 8.25cm x 6.6cm
-
An ammonite pair is made from a single ammonite fossil that has been cut in half and polished to create two matching mirror-image pieces.
-
Ammonites are extinct marine animals related to modern squid and octopus, and they lived in the oceans from about 400 to 66 million years ago.
-
The fossilised shell is spiral-shaped and divided into internal chambers, which can be seen clearly when cut open.
-
Inside many ammonite pairs, the chambers are filled with minerals such as calcite or aragonite, which can form crystal-lined cavities.
-
Some ammonite pairs (including this one) show bright colours caused by thin layers of fossilised shell that reflect light, while others have more earthy tones depending on mineral replacement.
-
Each pair is unique, as the internal crystal patterns and colours vary from fossil to fossil.
-
Ammonite pairs are commonly sourced from locations such as Madagascar, Morocco, and parts of Canada.
-
Ammonite pairs are valued for their age, natural symmetry, and the clear view they provide into the internal structure of an ancient fossil shell.
