Gem Dinosaur Bone
Gem grade agatized dinosaur bone is one of our favorite materials to collect and use in jewelry and lapidary art creations. Our collection greatly exceeds these examples but the photos in this set are some of our favorites.

What we call gem dinosaur bone is technically known as silicified fossil of dinosaur bone (agate is a form of quartz, which is a form of silica). The colors in agatized dinosaur bones come from trace minerals in the silica solution that replace the bone during petrification. In the best cases the incredible details of the cellular structure of the original bone have been reproduced, leaving the pattern in bone we refer to as cell patterns.
Dinosaur bone is a gemstone with a magical allure, enduring and preserving a bit of our past.

Non-gem grade fossilized dinosaur bones are found in many places around the world but the highly agatized and beautifully colored & patterned dinosaur bone known as "gem bone" is almost exclusively found in the four corners region of the Colorado Plateau in the USA (where the states of Arizona, New Mexico, Utah, and Colorado touch). Most of our bone was collected in Utah.


We have a great deal of respect for this extraordinary material. We choose to use the smaller chunks, slabs and incomplete specimens of top jewelry-grade bone for our work, while leaving the prized collector pieces intact. We have a passion for this material and show-case gembone in our jewelry as a means of sharing that with others.

We strive to be as eco-friendly as possible with both our private family life and our business practices. We use recycled precious metals, fair-trade and eco-friendly gemstones and we utilize as many non-toxic jewelry-making techniques as we can. We support small local family businesses whenever possible.

This set includes some our published gem dinosaur bone jewelry/specimens..... one of our rings was featured on the cover of Renee Newmans' Exotic Gemstones Vol 2.

*I have also included some coprolite jewelry within this album. Coprolite in agatized, gem-grade fossilized dinosaur dung.
