Boulder Opal Wood Fossil Replacement (often just called Wood Replacement Boulder Opal) is a type of natural opal that forms when silica-rich water slowly replaces the organic material of ancient wood, molecule by molecule, over millions of years. This rare process fossilizes the wood structure while filling it with vibrant opal.

🔹 Key Features:

• Natural Opal Replacement: The wood is entirely replaced by opal, not just coated.

• Preserved Wood Texture: You can often see wood grain, rings, or organic textures.

• Vibrant Play-of-Color: Commonly displays electric blues, greens, or even rare reds and purples.

• Natural Formation: No two pieces are alike—each one tells a geological story from millions of years ago.
