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.
