Rare Polished one side display slab of Prehnite from Australia

This specimen measures 3.3 x 2.9 x .25 inches
( 84 x 74 x 6mm) and weighs 0.2 lbs ( 94g)
This slab is a fine specimen of the rare marra mamba tiger iron. Mined only from the crocidolite seams of the
Hamersley Range in the Pilbara region of Western Australia, it displays far thicker and more complex bands of
golden chatoyant tiger's eye, red jasper and shimmering black hematite than the more common version of tiger's
eye. It is also streaked and patched with areas of blue, gray and green. The resulting stone, when sliced and
polished, looks like abstract art, the colors combining and flowing into one another like unmixed oil paint, distinct
but intertwined. This specimen is polished on the face and has adhesive remnants on the unpolished back which
is left over from being displayed in the Forum Shops on the Las Vegas Strip by the previous owner. This specimen
measures 4.4 x 3.9 x 0.25 inches ( 111 x 100 x 6mm) and weighs 0.43 lbs (196g)
