Ammolite vs Ammonite | What's the Difference? - Rare Earth Gallery

AMMOLITE OR AMMONITE?

An Ammonite is the commonly used word describing ammonoids. Ammonoids were a large and diverse group of sea creatures similar to cephalopods like cuttlefish, squids, octopuses and even the modern Nautilus. With tentacles like a squid and a multi-chambered shell, these were the most diverse and widely found creatures on earth from the Antarctic to the Great Plains. There have been over 10,000 species of different ammonites over time and they have even survived two of earth's three major extinction events, unfortunately the last one 66 million years ago killed off their main food source, marine plankton.

⚡ Quick Answer

An ammonite is the fossilized shell of an ancient sea creature — a cephalopod related to squid and the modern nautilus — that lived hundreds of millions of years ago. Ammolite is the rare, iridescent gem material formed from that fossilized shell, flashing red, green, blue, and orange. In short: the ammonite is the fossil, and ammolite is the gemstone made from it. Scroll down for the full comparison.

Ammonites as Index Fossils

Due to their longevity and unique suture connections, ammonites are a great index fossil. Index fossils help to age and date other fossils, especially if they're in the same marine rock.

What Is Ammolite?

Ammolite is when the fossil is opalized and gives them an iridescent sheen of red, blue, orange and more. When the Ammonite shell fossilizes the shell can form Ammolite on the outside.

Spiritual and Metaphysical Meaning

Spiritually Ammonites or Ammolites are very powerful earth healing fossils. The spiral shape symbolizes continual change and evolution. Ammonites stimulate the life force (Chi) within humans. Ammonites are often used for activating Kundalini and life path energies. The Ammonite is also often recommended to put in the home to attract health, prosperity and success.

Frequently Asked Questions About Ammolite and Ammonite

What is the difference between ammolite and ammonite? ▼

An ammonite is the whole fossil of an ancient, spiral-shelled sea creature, while ammolite is the thin, iridescent gem layer that can form on the outside of that fossilized shell. Put simply, the ammonite is the fossil itself and ammolite is the colorful gem material made from it. Every piece of ammolite comes from an ammonite, but not every ammonite develops ammolite.

What is an ammonite? ▼

An ammonite is the fossil of an ammonoid — a group of extinct sea creatures related to modern cephalopods like squid, octopus, and the nautilus. They had tentacles and a coiled, multi-chambered shell, and with more than 10,000 species they were among the most widespread animals on Earth before dying out about 66 million years ago. Their distinctive coiled shells make them excellent index fossils for dating rock layers.

Is ammolite a fossil, and what is it made of? ▼

Ammolite is an organic gemstone made from a fossil — specifically from the aragonite shell of certain ammonites. Over millions of years, the shell's microscopic mineral layers survive and refract light, producing ammolite's flashing sheen of red, green, blue, and orange. Because it comes directly from a fossilized ammonite shell, ammolite is considered both a genuine fossil material and one of the few gem-quality organic gemstones.

What are pyritized and opalized ammonites? ▼

The terms describe how an ammonite fossilized. In an opalized (or opalised) ammonite, the shell takes on an iridescent, opal-like play of color — this is the process behind ammolite. In a pyritized ammonite, the shell is replaced or coated by pyrite (fool's gold), giving it a metallic golden shine. Both are prized by collectors and simply reflect the different minerals present as the fossil formed.

Is ammolite a gemstone? ▼

Yes. Ammolite is recognized as a rare organic gemstone, in the same broad family as pearl and amber, because it is made from once-living material rather than a crystallized mineral. Its brilliant, shifting colors make it popular in pendants, rings, and other jewelry, and high-grade ammolite showing several bright colors is especially sought after.

How are ammonite and ammolite used in jewelry? ▼

Whole or polished ammonite fossils are often set as striking pendants and statement pieces that show off the natural spiral. Ammolite, with its gem-quality iridescence, is cut and set into pendants, rings, and earrings, frequently backed and capped for durability. Both make distinctive jewelry precisely because each fossil is millions of years old and no two are exactly alike.
