An Australian wood replacement opal is a unique type of opal formed when wood is gradually replaced by opal minerals over millions of years.
This process happens as silica-rich water fills in the spaces left by decayed wood, leaving behind a fossilized form of the wood with vibrant opal colors.
These opals often showcase an array of colors, ranging from deep blues and greens to fiery reds and oranges, with intricate patterns resembling the original wood grain. Australian wood replacement opals are highly prized for their rarity, natural beauty, and fascinating geological history.
