%X A dark and lead to silver grey soft irregular-shaped with heavy weight stone has been analysed as
a part of research work for determining the components of the stone thereby
leading to identify curiously to
pinpoint whether the stone is in a category of gemstone, radioactive elements,
raw or ingredients for making a powerful bomb or otherwise. In addition to the
physical and optical parameters measured such as specific gravity, hardness, luster,
transparency, cleavage, streak and other associated minerals for identification
of unknown stone, Powder X-ray diffraction (PXRD) is one of the primary
techniques in identification of minerals to examine the physico-chemical
make-up of unknown materials, and has also been employed
using Philips, DY993 X-ray Powder Diffractometer. The diffraction spectrum has
been measured with the proportional counter in the 2° to 100° range at room
temperature 300 K. This study reveals that the stone is not a category of
precious stone; instead it is a category of mineral deposition, PbS, Galena.
