Exceptional Marra Mamba Tiger's Eye Bowl
Mount Brockman Station, Western Australia
Only rarely do Marra Mamba specimens find their way to market, as the source for this brilliant stone has now been mined out. Fortuitous geologic circumstances produced the limited deposits of this material, located in central Western Australia, more than 1,000 kilometers northeast of Perth. Over millions of years, water heated by volcanic activity dissolved much of the silica from the banded iron formation in this region, leaving huge iron ore deposits of almost pure hematite. In other places, red and yellow iron oxides and/or silica were deposited as veins or replaced the wall areas of fine cracks in the host rock. The resulting stone, a highly sought-after variety of tiger's eye, is found only in this region.
The present decorative and functional bowl displays spectacular bands of golden tiger's eye and brilliant red jasper. The gentle curves of the layers are a testament to the immense pressures to which the rock was subjected over the millennia. Measuring 14 x 10 x 6 in
