Green kryptonite has been used in a wide range of manners.

Other uses

Using kryptonite in combination with electricity, heat, or other media can cause numerous side effects among normal human beings.

Kryptonite seemingly possesses a variety of chemical characteristics and can be readily formed into all three states of matter. It occurs naturally in the solid mineral state. However, it can be readily melted into liquid and mixed with other solutions, and can also be vaporized into a fine mist or gas.

Used in jewelry

Kryptonite is occasionally used to make jewelry. Though not highly sought, it can be aesthetically pleasing. In Smallville, kryptonite jewelry is sometimes a token of personal memories from the meteor shower, which caused a lot of damage and some deaths. Some kryptonite jewelry was also used on Krypton.

  • Lana Lang wore a necklace with a meteor rock crystal on it which she gave to her boyfriend Whitney Fordman. Eventually, Clark obtained the necklace, but the radiation from the stone was neutralized by his spaceship, turning it clear. (See main article: Lana's necklace)

Red Kryptonite necklace

  • The Smallville High Class of 2005 was given class rings containing red kryptonite. Clark's class ring was destroyed by his father Jonathan Kent. Clark eventually put on another ring when he ran away to Metropolis the following summer to rid himself of his guilt, responsibility, and inhibitions. Alicia Baker also used the stones from a ring to make a necklace for Clark in an attempt to get him to run away with her.

Somehow the clone of Jor-El's wife Lara-El was able to have the ring when she was brought back to life through the blue crystal, and gave it to her son Clark as a part of Kryptonian tradition, unaware that it would take away his abilities. It was unbreakable, so Clark could not get it off until the blue crystal was destroyed. Zor-El studied the mineral's properties during an earlier trip to Earth. (See main article: Victory ring)
  • Seven months after he disappeared, Lex Luthor planned revenge against Clark and Lana. He was wearing a new green kryptonite ring with a letter "L" in the center of it. When he was apparently killed in an explosion by Oliver Queen, the ring was retrieved by Oliver.
