Ammolites are a semi precious gemstone variety of natural fossils known as Ammonites. The nacreous shell of the ammonite is comprised of alternating layers of aragonite and conchiolin. Under certain conditions related to fossilization, the nacreous shell becomes highly iridescent; the resulting gemlike material is called "ammolite." The human eye perceives this as an flash of iridescent colors.
Cabochons are stones cut for jewelry and are measured in mm. One inch is equal to about 25 mm.
