This specimen is a custom-cut, mini slab of dolerite bluestone recovered downstream from the quarry at Craig Rhos-y-Felin located on the northern flank of the Preseli Mountains near Pembrokeshire, Wales. Recent petrographic studies have closely linked chippings from these dolerite bluestones to the bluestones installed at Stonehenge roughly 4,500 years ago.
