Gloom's branched evolution family as demonstrated in the anime: both of Gloom's potential evolutions require an evolutionary stone.

An evolutionary stone (Japanese: 進化の石 Evolution stone) is a stone-like item that radiates a mysterious energy that causes some species of Pokémon to evolve.

Another stone, the Everstone, is different in that it radiates a type of energy that prevents Evolution in the holders; however, if a Pokémon holding the Everstone has an evolutionary stone used on it, it will still evolve.

Evolutionary stones may be used at any time, and cause instant Evolution in the Pokémon they are used on, which cannot be canceled. With the exception of the Everstone, which must be held for its effects to take place, all evolutionary stones are applied directly to the Pokémon. All stones that cause Evolution in a Pokémon are consumed upon that Pokémon's evolution.

Many Pokémon that result from a stone-based evolution have vastly different level-up learnsets than their pre-evolutionary forms, with several learning no moves after Evolution at all.

List of stones

In the anime

A giant Moon Stone

In Clefairy and the Moon Stone, a giant Moon Stone appeared deep within Mt. Moon, being worshipped by a group of Clefairy who lived there. It was soon stolen by Team Rocket, and ultimately ended up being blown up; the shards from the shattered giant Moon Stone rained down on the Clefairy and caused some of them to evolve into Clefable. In this episode, the characters speculated that the Moon Stone was how various Pokémon—Clefairy in particular—arrived in the Pokémon world.

In Electric Shock Showdown, Nurse Joy gives Ash a Thunderstone so that he could evolve his Pikachu in order to defeat Lt. Surge's Raichu. Pikachu, however, refused the offer. Ash kept the Thunderstone in case Pikachu ever wanted to evolve; however, in Pika and Goliath!, a similar scenario occurred and Pikachu still refused to evolve. Seeing his determination to not evolve, Team Rocket stole it, planning to sell it.

The remaining Generation I evolutionary stones made their debut in The Battling Eevee Brothers, as part of a collection held by the Eevee brothers. Additionally, two of the Eevee brothers offered a Fire Stone and Thunderstone to Brock and Ash to evolve their respective Vulpix and Pikachu, though both refused.

The Leaf Forest appeared in The March of the Exeggutor Squad, which is a reported hotbed of Leaf Stones. The radiation from these stones in the forest is so strong that it caused Melvin's Exeggcute to evolve.

A fake Leaf Stone, made by Team Rocket, appeared in Make Room for Gloom, where the discovery of its nature as a fake was central to the episode.

A real Leaf Stone first appeared at the very end of Pikachu's Rescue Adventure. With it, the Exeggcute that had been following Misty's Togepi evolved into an Exeggutor.

Ash won a Sun Stone in the Bug-Catching Contest during The Bug Stops Here, later using it to evolve a Sunkern in Moving Pictures.

Fire Stones played an important role in The Stolen Stones!, where they were intended to be delivered to a stadium as a prize for competitors.

Both a Leaf Stone and a Sun Stone appeared in Whichever Way the Wind Blows during an explanation of the branch in Gloom's evolutionary line.

In Once in a Mawile, a Water Stone belonging to Samantha appeared, which Brock's Lombre used to evolve into Ludicolo. This is the first time that a main character's Pokémon evolves via an evolutionary stone on-screen, although it is likely that James's Weepinbell was evolved using a Leaf Stone prior to The Breeding Center Secret.

A Moon Stone appeared in a flashback in Delcatty Got Your Tongue?, evolving Dr. Abby's Skitty into a Delcatty.

In Stopped in the Name of Love!, Dawn gave an Everstone to her Piplup to prevent him from evolving until he changes his mind.

Professor Oak gave a Water Stone to a wild Lombre in A Faux Oak Finish!, while a Dusk Stone was central to the plot of Try for the Family Stone!.

Ursula used a Fire Stone and a Water Stone to evolve her two Eevee in Last Call, First Round!, making them a Flareon and Vaporeon, for use in the Grand Festival.

Ash had to find a Thunder Stone as part of a scavenger hunt in Climbing the Tower of Success!. He came across a young man in possession of one who tried to toss it to him from a long distance. The Thunder Stone nearly came in contact with Pikachu but he jumped out of the way just in time leaving Ash to catch it.

Mystery on a Deserted Island! featured all evolutionary stones available as of Generation V.

A Thunder Stone appeared in To Catch a Pokémon Smuggler! as a part of Clemont's explanation of how Pokémon Evolution works, Pikachu's evolution into Raichu working as an example of stone-induced Evolution.

A full set of evolutionary stones was seen on display in a stone shop in Geosenge Town in The Cave of Trials!. In addition, an unnamed Trainer used a Sun Stone purchased from the shop to evolve his Helioptile into Heliolisk. Clemont then revealed that he had also used a Sun Stone to evolve his own Helioptile into Heliolisk.

Evolutionary stones do not seem to be required for evolution in the anime as they are in the games. James's second Weepinbell evolved without a Leaf Stone in Here's Lookin' at You, Elekid. In addition, Pokémon that evolve via proximity of evolutionary stones apparently seem to control their evolutionary urges and physically touch the stone without evolving, as evidenced by Pikachu whacking away the Thunder Stone when refusing to evolve the first time, as well as a Clefairy holding onto a Moon Stone for prolonged periods of time before delivering it to the larger Moon Stone without evolving.

Pokédex entries

Mystery on a Deserted Island!

In the manga

In The Electric Tale of Pikachu manga

Evolutionary stones in a shop in Stone Town

In Clefairy Tale, Ash, Professor Oak, and Bill witness a Clefairy evolution ceremony involving a large Moon Stone.

The focus of the chapter To Evolve or Not to Evolve, That Is the Question! is evolutionary stones. Misty hopes to buy a Water Stone for her Poliwhirl in Stone Town, a town on Dream Island where all the evolutionary stones in the Pokémon world come from. However, she cannot afford one, remarking that an inexpensive one might make the evolution go bad.

She is later given a Water Stone by Mikey, who is being pressured to join the "Knights of the E Stone", a club which requires members to own a Pokémon evolved by an evolutionary stone. By battling club members, Ash and Mikey prove to the leaders that Pokémon which have evolved by evolutionary stone are not necessarily superior to their unevolved counterparts.

In the Pokémon Adventures manga

A Moon Stone was first mentioned by Professor Oak in Gyarados Splashes In! as a rock with a crescent moon-shaped indentation that boosts a Pokémon's power immensely. In the next round, Raging Rhydon, Team Rocket searched for one in Mt. Moon, however, it was Red who eventually found it. Later on, Red used this Moon Stone to evolve Green's Clefairy during the Silph Co. catastrophe.

In Buzz Off, Electabuzz!, Red's Poliwhirl was able to evolve into a Poliwrath with the help of a Water Stone when they were thrown into the water in Vermilion Harbor, although the cause of his evolution wasn't revealed until the Yellow chapter.

In The Kindest Tentacruel, Yellow found a Leaf Stone at the bottom of Vermilion Harbor, but the Fire, Thunder, and Water Stones were missing. Later, it was revealed Giovanni gave them to Red so he could evolve and devolve his Eevee freely. Noticeably though these four evolutionary stones don't disappear when used to evolved a Pokémon, allowing them to be used an unlimited amount of times.

In The Last Battle VI, Gold's Sunkern evolved into a Sunflora because the sun's energy reflected off of the rocks near Ilex Forest replicated the Sun Stone's effects.

In Guile from Mawile, Ruby's Skitty evolved into a Delcatty due to being exposed to one of Steven's Moon Stones.

In Give It Your Best, Blastoise, during the battle against the Deoxys Duplicates, Green evolved her Jiggly and Nido into Wigglytuff and Nidoqueen, respectively, using two Moon Stones.

In Leaping Past Lopunny, a Shiny Stone and Dawn Stone were seen amongst the rare stones that Steven had found during his stay in Sinnoh.

In Dealing With A Koffing Fit, Silver's Murkrow evolved into a Honchkrow due to gaining experience while holding a Dusk Stone, which had been given to Silver by Green.

In All About Arceus VIII, Gold's Togetic evolved into a Togekiss shortly after evolving from a Togepi using the Shiny Stone that had been given to him by Lance.

In Triple Threat, Cilan, Chili, and Cress used a Leaf Stone, Fire Stone, and Water Stone to evolve their Pansage, Pansear, and Panpour into Simisage, Simisear, and Simipour, respectively, during their battle against the Shadow Triad.

In Homecoming, it was revealed that Black's Musha evolved into a Musharna using a Moon Stone from Caitlin.

In PAORAS00, Sapphire's Kiruru evolved into a Gallade due to a Dawn Stone hitting him while training with Rara, who had evolved into a Gardevoir. Later, Steven found another Dawn Stone on the ground.


In the Pokémon Diamond and Pearl Adventure! manga

In (Violent) Earthquake! Cyrus's Consuming Ambition!!, it was revealed that Mitsumi secretly attached an Everstone to Hareta's Piplup before he started his journey, because she had thought Hareta would learn faster with weaker Pokémon. After Mitsumi removed it, Piplup immediately evolved into Prinplup, then into Empoleon.

In the Pokémon Zensho manga

In Indigo Plateau, Satoshi's Pikachu used a Thunder Stone to evolve itself into a Raichu before Satoshi left to challenge the Elite Four.
