Each Rainbow Ammonite is a breathtaking fossil from Madagascar, formed millions of years ago from an extinct, squid-like marine mollusk. What makes these fossils truly special is their natural iridescence — flashes of blue, green, red, and purple shimmer across the surface as light dances over preserved microscopic layers of aragonite (mother-of-pearl.)

These colors are completely natural and occur through a rare process where light diffracts within the fossilized shell structure. No dyes, no treatments, just pure Earth magic.

Each piece is 100% natural material and is entirely one of a kind. Variations in color, pattern, texture, and small natural imperfections are to be expected and celebrated—they’re part of what makes every Rainbow Ammonite uniquely beautiful.

Perfect for collectors, crystal lovers, fossil enthusiasts, or anyone drawn to ancient ocean energy and bold, rainbow shine.
