iridescent ammonite

Product Overview

This exquisite ammonite specimen is a palm-sized window into the prehistoric oceans. A member of the extinct group of marine mollusks, this shell has undergone a stunning transformation over millions of years. While many ammonites are valued for their geometric "suture" patterns, this particular piece features a rare iridescent layer. When caught in the light, the surface displays a delicate red and green sheen—a natural phenomenon caused by the light reflecting through layers of aragonite within the fossilized shell.

Origin & Location

Specimens featuring this specific red and green iridescence are most commonly sourced from the Mahajanga Basin in Madagascar, though similar iridescent fossils are found in various high-quality deposits worldwide.

Specifications

• Material: Iridescent Ammonite Fossil

• Dimensions: Approximately [Insert Size, e.g., 3–4 inches] (Palm-sized)

• Weight: Light and easy to handle

• Color Palette: Natural earthy tans and greys, highlighted by luminous flashes of fire-red and emerald-green.

Key Features

• Natural Iridescence: The shell retains its original mother-of-pearl layer (nacre), which has fossilized into a shimmering, "opalescent" finish.

• Classic Fibonacci Spiral: The specimen perfectly showcases the logarithmic spiral growth pattern that makes ammonites a favorite for collectors and artists alike.

• Tactile Appeal: Polished to a smooth, comfortable finish, this piece fits perfectly in the hand, making it an ideal "pocket stone" or meditation aid.

• Vibrant Flash: The red and green colors are not fixed; they shift and "glow" as the angle of light changes, giving the fossil a sense of life.

Important Notes

• Authenticity: This is a genuine prehistoric fossil. The colors are entirely natural and have not been enhanced with dyes or coatings.

• Fragility: While stone-like, the iridescent layer is thin and can be scratched. Handle with care and store away from harder minerals.

• Cleaning: To maintain the flash, avoid using water or oils which can dull the iridescence over time. A simple wipe with a dry, soft microfiber cloth is recommended.
