Lex Luthor used a green kryptonite ring to protect himself from approaching Kryptonians; this particular ring is a square shaped ring covered with a kryptonite gem. The ring has an L underneath the gem, to signify the name Lex or Luthor.

When he was separated from his inner evil self due to black kryptonite, an incarnation of him dubbed "Alexander Luthor", was released and he used this green K ring to overpower Clark Kent. Clark later used his heat vision to turn the green K into black K, fusing the two versions of Lex back together. It is unknown what became of the black kryptonite ring.

Another green K ring was seen on Lex's right-hand ring finger in a caravan-based laboratory, and he was seen watching Clark and Lana Lang on the Daily Planet rooftop. Oliver later took it with him.

Oliver Queen, a shareholder of LuthorCorp stocks, later used this ring to defeat Rudy Jones, a powerful metahuman who stole Clark's abilities through his absorbing powers ability, and he returns Clark's powers to him.

Action Comics # 654.

After discovering that the villain Metallo was powered by a heart made of kryptonite, Lex Luthor used a sample to fashion a kryptonite ring for himself. He wore the ring at all times in an effort to keep Superman away from him. Continued exposure to the low level kryptonite radiation proved harmful however and Luthor developed cancer. To keep the cancer from spreading, his right hand was amputated and replaced with a cybernetic prosthetic. When Lex Luthor cloned himself a new body, the cybernetic appendage was no longer necessary.

The ring eventually came into the possession of the Batman. Clark entrusted the ring into the care of Bruce Wayne his closest ally, who keeps the ring secured in the Batcave in case Superman ever loses control of his powers or if he falls under the control of an evil influence. On several occasions Batman has been required to use the ring to keep Superman at bay so usually it's located in his utility belt in a lead-lined case. In one case Batman's partner Robin, had to use the kryptonite ring in order to keep Superman's clone Superboy under control.
