This extraordinary cabochon is cut from the agatized fossil of a dinosaur that once walked the ancient floodplains of the Four Corners region—where Arizona, Utah, Colorado, and New Mexico converge. Long before deserts and mesas claimed the landscape, this was a land of towering conifers, shallow inland seas, and enormous creatures whose bones now echo through time.

What you’re holding is a genuine piece of one of those ancient beings, preserved not in dust, but in agate—a transformation that took tens of millions of years under exacting geological conditions. Known as DinoGemBone, this material is rare in any form—but this specimen is truly exceptional.

Measuring 46mm x 34mm and weighing 16.81 grams, this piece boasts a stunning mosaic of well-defined fossilized cell structures lit by an unbelievable palette of color:

Orchid pinks, electric blues, glowing golden yellows, and even soft lavender and violet flashes. These colors result from a perfect storm of trace minerals—manganese, iron, and silica—infused during the slow fossilization process. Most DinoGemBone exhibits earth tones—reds, browns, blacks. But to find a piece with pinks and blues, let alone yellows, is almost unheard of.

Each polished cell is a portal into deep time, a crystallized echo of marrow and life from a lost era. This is more than a gem—it’s a geological biography, a moment of ancient motion captured in stone.

Whether you’re a collector, lapidary artist, or someone who feels the weight and wonder of the past, this piece is a once-in-a-lifetime offering. Available for custom jewelry or as a centerpiece in any high-grade collection.
