BANDED IRON TIGER EYE SPECIMEN
MT BROCKMAN STATION, AUSTRALIA
From the early Proterozoic (circa 2.5 billion years ago) the panel of Marra Mamba iron formation cut and polished in the form of a table top
31 7/8 x 18 7/8 x 1 1/8 in. (81 x 48 x 3 cm.)

专家说明

Found only in the blue crocidolite seams of the Hamersley Range in the Pilbara region of Western Australia, this highly iridescent ironstone, Marra Mamba, is amongst the rarest and most colourful of all Tiger-eye. Probably stromatolitic in origin, this fossil is amongst the earliest signs of life on Earth, and as a semi-precious stone is also one of the most beautiful.
