Ammonites (or Ammolites) are organic gems which are the fossils of mollusks that lived up to 395 million years ago! Over millions of years after the mollusks died, the insides of their shells were replaced with minerals. These minerals vary, but can include pyrite, silica, calcite or aragonite.

Ammonites are used for jewelry in such countries as the United States, Canada and England. They are also occasionally marketed under the name “korite.”

When looking to purchase an Ammonite, the more iridescent colors the better! These colors can range from gray to brown, but highly prizes Ammonites will show flashes of green, red, purple and orange. The most colorful ones will be used in jewelry. What I love about them is that each one is different from the next, so you get a completely unique look! Manufacturers will often cut Ammonites as free form in order to retain the most color and beauty, so you can truly create a one-of-a-kind look. You will also find Ammonites in shapes such as squares, cabochons and ovals.
