Where Do Dinosaur Bones Come From?

March 14, 2013 2 min read

Dinosaur Bone Jewelry is Popular, Unique and, YES, it's REAL.

We field a ton of questions regarding our dinosaur bone rings and other accessories. Is it real? Is it ethical to use in jewelry? How do I know it's real dinosaur bone in my jewelry? Can I get t-rex bone in my ring? Here, you'll find information to answer all of those questions and more.


Gembone Jewelry

Before going any further, it's important to note that, our dinosaur bone jewelry is not crafted using whole or partial skeletal remains of a dinosaur like the ones you'd see on Dinosaur 13. The material we use in our dinosaur bone rings and other accessories is called gembone and is believed to be one of the rarest of gemstones.

What is a gembone?

A gembone is the fossil of an animal bone that contains gem quality minerals. It is sometimes also referred to as mineralized dinosaur bone, silicified dinosaur bone and agatized fossil. These gembone specimens can be traced back to dinosaurs that roamed the earth around 150 million years ago.

Where is gembone found?

The most highly agatized, beautifully colored and patterned dinosaur gembone is almost only found in the four corners region of the Colorado Plateau in the USA (where the states of Arizona, New Mexico, Utah, and Colorado touch). Here at Jewelry by Johan, we source our gembone from multiple suppliers who excavate it from the Morrison Formation in Utah which covers 600,000 square miles over several states.

What does gembone look like?

The different colors and very unique pattern in gembones are caused by minerals such as chlorite, chromium, iron-oxide and manganese that enter the cells during formation. Because of the unique and rare colors and patterns found in these fossils, and the very slim odds of a dinosaur bone not only becoming a fossil, but also being fossilized with gem quality minerals, gembone have earned gembone recognition as the "World's Greatest Treasure".

How do I know if gembone is real?

We stand behind the authenticity of all of our materials and all of our dinosaur bone jewelry comes along with a certificate of authenticity.
