Stone: Very Rare A+++ Blue Chalcedony on Stand, Turkey Weight: 3236.45 ct Size: 165x60x60mm Treatment: None Origin: Turkey It is a fossil wood dating back 200 million years, all parts from a log or branches have been silicified, meaning that organic components were little by little replaced by silicon in the form of jasper, chalcedony and more rarely opal. Without the organic parts, all the living matter was replaced by stone : there are growth rings, cell separations, almost like worm cracks. Its features are those of the mineral that would have pseudo-transformed the wood : the silicon. And that’s what we call a "petrified wood" in the common language.
