Fantastic Ammonite Fossil Necklace from Madagascar - Natural Designer Gemstone

This exceptional necklace features a genuine Ammonite Fossil from Madagascar, expertly preserved to showcase the specimen’s intricate coiled shell and its characteristic warm brown hues.

Ammonites, key marine invertebrates from the subclass Ammonoidea, first appeared approximately 240 million years ago and thrived until their extinction around 65 million years ago, coinciding with the dinosaurs’ demise.

As free-swimming predators related to modern cephalopods like squid and octopuses, ammonites used their multiple long arms to capture prey. Their chambered shells, filled with liquid and gas, functioned as sophisticated buoyancy devices, enabling them to navigate ancient seas with ease.

Today, Ammonite fossils are commonly found embedded in sedimentary rocks spanning the Devonian through the Cretaceous periods, often exposed in mountain outcrops and sedimentary basins worldwide.
This necklace not only serves as a stunning natural gemstone accessory but also as a tangible link to deep geological time and the complexity of ancient marine ecosystems.

All Henryka Jewellery comes complete with a beautiful presentation / gift box.

Beautiful Gemstones Designed by Nature

The Henryka Designer Gemstones Collection is a celebration of completely natural and beautifully rare gemstones from across the world.

Each gemstone is carefully hand-chosen by us for its natural and un-treated colours and patterns. We look for vibrant gemstones we know you will love, as well as rare gemstones you may have never even heard of from all corners of the earth.

Instead of seeking perfection, we choose gemstones based on the natural quirks and inclusions that make them entirely unique. This means incredible stripes, bold spots, wave-like ripples and swirls that give each gemstone its own unique fingerprint.

These characterful gemstones are then cut, polished and set BY HAND into silver jewellery designs, from statement necklaces to rings, earrings and bracelets. When wearing a piece of Henryka Designer Gemstone jewellery, you can be assured that no one will ever be wearing the same piece. It is individual to you.
