Madagascar Septarian Dragon’s Egg – Natural Crystal Geode

A Jurassic Relic, Cracked Open to Reveal Its Secrets

This striking Septarian “Dragon’s Egg” from Ambondromamy in the Betsiboka Region of Madagascar is a true natural sculpture, shaped and polished into a classic egg form and opened to reveal a dramatic, crystal-lined interior. The contrast between the smooth, patterned outer shell and the dark, sparkling crystal cavity makes this piece instantly eye-catching and full of character. Weighing 2853 grams and measuring approximately 155mm high, 125mm wide and 115mm deep, it is a substantial display specimen with real presence.

Septarian is a fascinating geological formation that began as ancient marine mud and sediment. As this material dried and shrank, it cracked, forming natural fissures. Over millions of years, mineral-rich fluids seeped into these cracks and slowly crystallised—most commonly forming calcite, aragonite, and limestone—creating the distinctive network of dark lines and segmented patterns that make Septarian so recognisable.

Specimens from this region of Madagascar date back to the Middle to Late Jurassic period, making them approximately 145 to 174 million years old—formed in a time when dinosaurs still roamed the Earth and vast shallow seas covered much of the planet.
