If Cleopatra the seventh was not lying down but standing, Zhang Zian would have noticed the amulet she was wearing.
It would be an insult to describe the eye of wajet amulet as a "priceless treasure". It was a real divine artifact, and was on the same level as the heirloom seal in China, or even half a level higher. The first reason was that the heirloom seal had only been born for one or two hundred years, while the eye of wajet amulet had existed for at least a thousand years or more. The second reason was that the heirloom seal represented the authority of the monarch, while the eye of wajet amulet represented the authority of God.
As for the gold and gems used to make the amulet, they were not worth mentioning compared to the symbolic meaning of the amulet.
The amulet was a dead object, and the carved eye could not move, but Zhang Zian looked down at the eye and felt that it was really looking at him.
