Madagascar Ammonite necklace for two.

This polished fossil ammonite comes from the warm prehistoric seas that covered Madagascar over 65 million years ago, during the Late Cretaceous Period. Ammonites were marine mollusks related to modern squids and octopuses, their spiral shells forming one of nature’s most iconic shapes.

Over millions of years, the original shell has been replaced by minerals, often revealing stunning earthy tones, iridescent flashes, and intricate internal chamber patterns when polished. Each piece is a unique natural work of art — a blend of fossil history and gemstone beauty.

Holding a Madagascar ammonite is like holding a snapshot of an ancient ocean frozen in time. Whether treasured as a collector’s fossil, used in crystal healing for grounding and transformation, or displayed as a striking natural décor piece, it offers both geological wonder and timeless elegance.
