What is ammonite? Origin and mineralogy

The name ammonite derives from the ancient creature "ammonite," from which it originates. The ammonite itself was named because its shape resembles the spiral ram's horn held by Amun, the ancient Egyptian sun god. It can truly be said that this gemstone is a place where ancient history and mythology intersect.

From a mineralogical perspective, ammonite is classified as a "biogenic organic gemstone." It is formed when a very thin layer of aragonite (calcium carbonate), its main component, adheres to the surface of ammonite fossils that lived during the Cretaceous period of the Mesozoic era, approximately 70 million years ago, and is transformed over long periods of time by the effects of pressure and heat underground.

These fine layers of aragonite cause light interference, creating a rainbow-colored shimmer, or "iridescence," similar to that seen in opal and nacre. This shimmer is the greatest appeal of ammonite.

The highest quality ammonite is found only in the Bearpaw Formation, located on the eastern slopes of the Rocky Mountains in southern Alberta, Canada. This region was once an inland sea, providing an ideal environment for ammonite deposition. Ammonites exhibiting particularly vibrant red and green colors are highly valued, while rarer shades such as blue and purple are even more prized.

The history and culture of ammonite

Ammonite has a relatively short history among gemstones, having only been officially recognized as a gemstone worldwide in 1981. Its beauty and rarity became widely known after being certified by the International Confederation of Precious Metals, Jewellery, and Jewelry (CIBJO).

However, the ammonite fossils from which ammonites originate have fascinated people around the world since ancient times. The Blackfoot people, an indigenous group in Canada, call ammonite "Iniskim" or "Buffalo Stone" and cherish it as a sacred amulet that brings success in buffalo hunts. It is also said to have been used for healing illnesses and in rituals.

In ancient Greece and Rome, ammonite fossils were known as "Amun's horns" and were believed to be amulets for receiving oracles or to ensure peaceful sleep when placed by one's bedside. In medieval Europe, they were called "snake stones," and legends persist that they were snakes turned to stone by a saint. Thus, ammonites are steeped in rich stories that transcend time and culture.

Ammonite and color psychology

The spiral pattern, a symbol of ammonite, represents growth, evolution, and the cosmic cycle in nature. Its shape, spreading outward from the center, symbolizes the flow of life energy and infinite possibilities, and is said to bring positive change and development to its owner.

The iridescent shimmer, which changes its appearance depending on the viewing angle, is a symbol of diversity, creativity, and hope. This multifaceted light is believed to unlock the latent potential dormant within the wearer, freeing them from preconceived notions and providing a multifaceted perspective.

In particular, the fiery red color (#E63922) emitted by ammonite symbolizes vitality, passion, and energy. This color is believed to enhance the wearer's energy, encourage action and decisiveness, and support a strong will to achieve goals.

As a power stone, it is popular worldwide as a "stone that attracts good fortune and wealth." In feng shui, the spiral shape of the ammonite is thought to improve the flow of energy, purify negative energy accumulated in the body, and create a positive cycle. Because it shines with seven colors, it is also said to bring balanced good fortune to its owner.

FAQ

❓ What is the difference between ammonite and ammolite?

Ammonites refer to the fossils themselves of cephalopods, which were closely related to squid and octopuses and lived during the Mesozoic era.

On the other hand, ammonite is a gemstone name referring to the part of an ammonite fossil where a layer of aragonite has formed on its surface, causing it to exhibit a rainbow-colored "play of color." Therefore, not all ammonite fossils become gem-quality ammonite.

❓ Are there any precautions I should take when caring for ammonite?

Ammonite is a relatively soft gemstone with a Mohs hardness of 3.5 to 4.5, making it susceptible to acids, heat, and impact. When cleaning, simply wipe it gently with a dry, soft cloth.

Absolutely avoid using ultrasonic cleaners or steam cleaners, and take care to prevent cosmetics, perfumes, hairspray, etc. from coming into direct contact with the jewelry. When storing, handle it carefully by placing it in an individual bag or divider in a jewelry box to prevent it from bumping against other hard gemstones.

❓ How are the iridescent colors in ammonite created?

The iridescent colors of ammonite are determined by the thickness of the thin layer of aragonite covering its surface. When light strikes this layer, the light reflected from the surface of the layer and the light reflected from within the layer interfere with each other. This interference of light amplifies certain wavelengths of color, which is what we perceive as iridescent colors.

Generally, thicker aragonite layers tend to appear red or green, while thinner layers tend to appear blue or purple.
