This is nature’s own art created millions of years so. Looking just as if a human painted a dainty bird against a background of wood, it is actually agate that grew inside a thunder egg that is made mostly of rhyolite. While some thunder eggs do accidentally form recognizable images, very few are so perfect as this one, found in Chihuahua, Mexico. Our 1” thick polished blocks stand upright on flat surfaces and are made from a superior cast method for clarity, depth and realism. The print is created by the artisan Giclee process and has been enlarged for a superb viewing experience. Makes a stunning showpiece on shelf, desk, table! Also, a great gift for any occasion and available in several shapes and sizes. Photo credit: Thomas Shearer.
