The paper mentions the most important types of the precious stone in the Assyrian era and the different fields in which these stones were used. For instance, they were employed in decorating the regal badges like the crown, the scepter and the clothes worn by Kings and gods. They were also used in manufacturing some fatal and cylinder seals, inlaying the regal furniture which was made of wood. They also were used in inlaying the ivory pieces, not to mention their vital role as invaluable jewels and embellishments.
