The amulet was a mystical gem which originally belonged to a man named Chesterman until his daughter, Simone, killed him and stole it.
Powers[]
The gem could hypnotize anyone who directly gazed into it and force them to obey the commands of the wearer, even Kryptonians were susceptible to it. The gem could influence a person's actions, behavior and even personality.
Weaknesses[]
The gem could only hypnotize an individual if they gazed directly into it. It couldn't affect targets through video and Simone often drew attention to the gem by stroking it while giving commands. The gem was also as fragile as any other stone, as a bullet fired from a gun was able to destroy it, which freed those under its influence.
Early life[]
Previously it was in possession of Simone's father Mr. Chesterman, a world-famous hypnotist who used the blue mystical gem around his neck to hypnotize his patients. Some time later Simone killed her father and started using the stone around her neck to hypnotize people whenever she needed it.
Season Five[]
Simone hypnotized Clark into kissing her at the Talon; they were caught by Lois Lane, who told Chloe Sullivan about their escapade. Later, at the Kent Farm, Simone told Clark to get Lana to the loft under the pretext of him needing some kind of help. Meanwhile, Clark revealed his powers to Simone who then told Clark to make love to her. Lana then arrived to find them kissing in their underwear in the loft at which point Clark, under Simone's control, broke up with Lana. Chloe and Lois had meanwhile searched for information on Simone, and their suspicions about her were furthered when Lana told Chloe about her encounter with Clark and Simone.
Simone orders Clark to make love with her
Simone reported back to Lex that she had completed her task; however, Lex had also expected her to find out Clark's secret, but she refused to divulge her findings. When Lex threatened to turn her in, Simone returned to the Kent Farm and told Clark they would be leaving for California. Before they left, Simone instructed Clark to make a stop at the Luthor Mansion and kill Lex. Clark barged in on Lex and nearly killed him, but Chloe arrived and weakened Clark with kryptonite. With Clark out of commission, Simone hypnotized Lex and told him to kill Chloe and himself, but Chloe struggled for the gun with him. In the process, the gun went off and shattered the hypnotic jewel, as well as killing Simone, freeing Lex and Clark from her control.
