This stunning cabochon is a rare relic of prehistoric life, carved from fossilized dinosaur bone unearthed in the ancient sediment layers of the Four Corners region—where the desert meets the echoes of long-lost giants. Once living, breathing creatures walked this land during the Jurassic and Cretaceous periods, and now, millions of years later, their legacy is captured in stone.

What makes this 58mm x 55mm cabochon so extraordinary isn’t just its massive face or its weight of 12.35 grams—it’s the sheer translucence and intense pink saturation held within its agatized cell structures. Blush pinks, shimmering rose quartz tones, and soft glassy luster glow from within each fossilized marrow chamber, making this piece feel alive with the whisper of deep time.

DinoGemBone is already rare—requiring a perfect blend of mineral-rich groundwater, pressure, and time to replace organic bone with colorful agate. But this piece pushes into an entirely different tier: its translucency lets light pass through the fossilized cells, giving it an ethereal, almost spiritual quality. You’ll also find delicate traces of lavender, peach, and faint gold, swirling through the pink matrix like fossilized fire.

Highly coveted by collectors and lapidaries alike, DinoGemBone of this caliber is nearly impossible to find today, especially in sizes this large and in colors this vivid. Most fossil bone cabochons are opaque, earthy, and small. This one is luminous—a portal into the marrow of the Mesozoic, transformed by geologic alchemy into wearable art.

Each cell is a signature of a vanished creature. Each pink glimmer, a testimony to the patience of time and the beauty born from ancient life.

Available for custom jewelry or as a standout collector’s piece. This is prehistoric elegance at its finest—and once it’s gone, there won’t be another.
