Wearable Prehistory, Set In Sterling Silver

About Our Fossil Jewelry

Every piece in our fossil jewelry collection carries something genuinely ancient. An ammonite that coiled through Jurassic seas 65 to 400 million years ago. A shark tooth from a creature that patrolled the ocean long before humans walked the earth. An orthoceras — a direct ancestor of the modern nautilus — preserved in stone for over 400 million years. We set each fossil by hand in 925 sterling silver, creating jewelry that's as scientifically fascinating as it is extraordinary to wear.

Our ammonite pendants and earrings showcase the famous spiral geometry that has inspired artists, architects and sacred geometry traditions across cultures for centuries. Fossilized shark tooth necklaces and pendants range from subtle everyday pieces to genuine statement jewelry. Orthoceras fossil rings and pendants feature the distinctive elongated chamber structure of this ancient cephalopod, often with dramatic contrast between the dark matrix and the pale fossil. Each piece is one of a kind — no two fossils are identical, which means no one else in the world owns exactly what you're wearing.

Fossil jewelry makes an extraordinary gift for the collector, the nature lover, the person who has everything, or anyone who wants to wear a piece of natural history.

Frequently Asked Questions

Is fossil jewelry made from real fossils?

Yes. Every piece in this collection is set with a genuine fossil — real ammonite, orthoceras, fossilized coral, fossilized shark teeth, or dinosaur bone. These are authentic prehistoric materials, not resin castings or imitations, hand-selected and set largely in 925 sterling silver.

How old are the fossils used in this jewelry?

It depends on the material. Ammonites and orthoceras are cephalopods that lived roughly 65 to 400 million years ago. Fossilized coral and Turritella agate preserve ancient marine life from tens of millions of years back. Fossil shark teeth are typically several million years old. Each piece is a wearable fragment of deep geologic time.

What is an ammonite and why is it used in jewelry?

An ammonite is an extinct marine mollusk whose coiled, spiral shell makes a striking natural design. Some pieces are pyritized, where the shell mineralized into golden pyrite, and rare opalized ammonite (ammolite) shows flashing iridescent color. The spiral shape is why ammonite is the most common fossil in this collection — it reads as both ancient and ornamental.

Is fossil jewelry a good gift for men?

It's one of the strongest natural-art gifts for men we carry. Fossilized shark tooth pendants and orthoceras rings have an understated, rugged character that appeals to collectors and anyone drawn to natural history. Because each fossil is one of a kind, the gift carries a story most jewelry can't.

What metal is your fossil jewelry set in?

The large majority of this collection is set in 925 sterling silver, with select rings on adjustable bands and some bezel-set and prong-set designs. Sterling silver holds detail well and pairs cleanly with the earthy tones of fossil material, from tan shark teeth to deep brown ammonite and red fossilized coral.

Will two fossil pieces ever look exactly alike?

No. Because each piece is cut from a unique natural fossil, no two are identical in pattern, color, or matrix. Even within the same style, every ammonite spiral and every shark tooth differs. When a piece sells, it is genuinely gone, which is why much of this collection shows very low stock.
