Jurassic World: Dominion is the 6th and final entry in the Jurassic Park movie franchise. The original Jurassic Park debuted almost exactly 29 years ago on June 11th, 1993, the same year that Park City Jewelers opened. Each time a new movie debuts, we’ve noticed a similar trend: People become more interested in dinosaur fossils and dinosaur bone jewelry and the cost of gem-quality dinosaur bone doubles or even quadruples. 

We’ve compiled a list of our most frequently asked questions about dinosaur bone jewelry. Whether your curiosity is piqued or you’re shopping for a rare and unique piece of dinosaur bone jewelry, here are some basics.

Gem-Quality Dinosaur Bone History

Gem-quality dinosaur bone is also known as gembone, agatized dinosaur bone, or dinogem. The fossils date back to the Jurassic period, about 150 million years ago.

How Does Gembone Form?

Gembone forms when dinosaur bones are mineralized. This process occurs when the minerals from groundwater replace the natural tissue and crystalize. This slow process requires specific conditions, and gembone is only found in one place on earth.

Where is Gem-Quality Dinosaur Bone Found?

Gem-quality dinosaur bone is only found in an area known as the Morrison Formation, which spans a large section of the western United States and Canada. More specifically, most gembone is discovered in the four-corners region of Colorado, Utah, Arizona, and New Mexico

Can You Tell Which Dinosaur the Dinosaur Bone Came From?

We get this question often. Unfortunately, there is no way to tell which dinosaur the specific fossil came from.

What Colors and Patterns Does Gem-Quality Dinosaur Bone Come in?

Gembone is found in various colors, including blue, green, orange, red, white, yellow, etc. Each piece has a unique cell structure that forms a unique pattern. Some patterns feature larger cell structures, while others are much smaller. The combination of color and cell structure makes each piece striking and beautiful.

How Rare is Gem-Quality Dinosaur Bone?

These pieces are extremely rare because they are only found in one area on the earth. They also vary significantly in their quality, making high-quality pieces especially rare. Park City Jewelers only uses the highest quality gem-quality dinosaur bone in our jewelry.

Dinosaur Bone Jewelry Care

We only use the strongest agatized dinosaur bone in the jewelry we create. That being said, it’s crucial to treat gembone jewelry with care. Avoid exposing your gembone pieces to harsh chemicals, including chlorine, household cleaners, acidic substances, cosmetics, and hairspray.
