Ammolite Pendant - Dainty Silver Ammonite Inlaid With Fire Opal In Vibrant Iridescent Hues

What You're Receiving

A dainty sterling silver pendant featuring a natural ammonite fossil inlaid with fire opal, producing a layered play of iridescent color that shifts with movement and light. Each pendant is one-of-a-kind — the ammolite shell's spectral patterning and the opal's internal fire are unrepeatable in any two pieces.

Geological Profile

• Ammolite: An opal-like organic gemstone derived from the iridescent aragonite shell of extinct ammonite cephalopods, primarily Placenticeras meeki and Placenticeras intercalare. Found almost exclusively in the Bearpaw Formation of the Rocky Mountain region (Alberta, Canada). Formed over 65–71 million years ago during the Late Cretaceous period.
• Iridescence Mechanism: Ammolite's spectral color play — ranging from crimson and gold to violet and green — results from light interference within stacked layers of aragonite platelets, each only 0.5–0.8 microns thick. Thicker layers produce reds and greens; thinner layers produce blues and violets.
• Fire Opal: A transparent to translucent variety of opal (SiO₂·nH₂O) distinguished by its vivid orange, red, or yellow body color. Formed in ancient volcanic deposits, primarily in Quéretaro, Mexico. Unlike precious opal, fire opal's value lies in its warm body color rather than play-of-color, though some specimens exhibit both.
• Mohs Hardness: Ammolite: 3.5–4.5 | Fire opal: 5.5–6.5 — both require protective settings, which the silver bezel provides.

Historical & Cultural Significance

Ammonites are among the most iconic fossils in natural history, named after the Egyptian god Ammon whose ram's horns they resemble. They thrived in Earth's oceans for over 300 million years before the K-Pg extinction event 66 million years ago. The Blackfoot Nation of the Canadian plains called ammolite Iniskim — the Buffalo Stone — and considered it one of the most sacred and powerful talismans in their tradition, used in ceremonies to call buffalo herds and ensure survival through winter. Fire opal was revered by the Aztecs as quetzalitzlipyollitli, the stone of the paradise bird, and was mined in Mexico long before European contact. Both stones carry deep indigenous and geological heritage that makes this pendant far more than decorative.

Metaphysical & Energetic Properties

• Ammolite: Associated with transformation, evolutionary energy, and the Fibonacci spiral of life; used in Feng Shui as a prosperity and vitality stone.
• Fire Opal: Linked to the sacral chakra — associated with creativity, passion, courage, and the awakening of personal power.
• Combined: The pairing of ancient fossil energy with fire opal's activating warmth creates a piece traditionally associated with grounded vitality and inspired action.

Care Instructions

• Store in a soft pouch or lined jewelry box — both ammolite and opal are relatively soft and can scratch against harder stones or metals.
• Avoid ultrasonic cleaners, steam cleaning, and harsh chemical jewelry solutions.
• Wipe gently with a soft, dry cloth after wearing.
• Keep away from prolonged heat and direct sunlight — opals contain water and can craze (develop surface cracks) if dehydrated.
• Remove before swimming, bathing, or applying perfume or lotions.
