[[File:Branched evolution.png|thumb|250px|right|Gloom's [[List of Pokémon with branched evolutions|branched]] [[evolution family]] as demonstrated in the anime: both of Gloom's potential evolutions require an evolutionary stone.]]
An '''evolutionary stone''' (Japanese: '''{{tt|進化の石|しんかのいし}}''' ''Evolution stone'') is a stone-like [[item]] that radiates a mysterious energy that causes some [[Pokémon (species)|species of Pokémon]] to [[Evolution|evolve]].

Another stone, the Everstone, is different in that 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.

The use of a stone is seen by many to be "forced" evolution, especially by the main characters of the anime, as the Pokémon is not in charge of its own transformation. Many Pokémon that result from a stone-based evolution also have vastly different [[level]]-up [[move|learnset]]s than their pre-evolutionary forms, with several learning no moves after evolution at all.

==In the anime==
[[File:Large Moon Stone.png|thumb|200px|A giant Moon Stone.]]
Evolutionary stones are showcased somewhat rarely in [[Pokémon anime|the anime]], as only a relative few Pokémon are able to evolve by using them. Despite this, they were among the earliest of items to have been showcased in the anime, appearing as early as ''[[EP006|Clefairy and the Moon Stone]]'', where a rather large Moon Stone appeared deep within [[Mt. Moon]]. It was being worshipped by a group of {{p|Clefairy}} who lived there, and was soon stolen by Team Rocket and ended up being blown up. The shards from it, however, rained down on the Clefairy and caused some of them to evolve into {{p|Clefable}}. It is also speculated in the anime that the Moon Stone was the reason why and how various Pokémon—Clefairy in particular—arrived in the Pokémon world.

The second appearance of an evolutionary stone occurred in ''[[EP014|The Electric Shock Showdown]]'', where the Thunderstone was introduced. This was likewise the first opportunity that a Pokémon belonging to a main character was given to evolve by stone. [[Ash's Pikachu]], however, refused the offer, intending to beat [[Lt. Surge]]'s {{TP|Lt. Surge|Raichu}} as a Pikachu. He kept the Thunderstone on hand, in case Pikachu ever wanted to evolve; however, in ''[[DP074|Pika and Goliath!]]'', the same scenario occurred and Pikachu still refused to evolve. Seeing his determination of not evolving, {{TRT}} stole it, planning to sell it.

The remaining Generation I evolutionary stones made their debut in ''[[EP040|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}}, respectively, to evolve their {{TP|Brock|Vulpix}} and Pikachu, though both refused.

A forest that appeared in ''[[EP043|The March of the Exeggutor Squad]]'', was a reported hotbed of Leaf Stones, and the radiation from these stones in the forest was so strong as to induce evolution in [[Melvin]]'s {{p|Exeggcute}}, which proceeded to cause chaos by hypnotizing a horde of other Exeggutor.

A fake Leaf Stone, made by Team Rocket, appeared in ''[[EP068|Make Room for Gloom]]'', where the discovery of its nature as a fake was central to the episode.

A real Leaf Stone finally appeared at the very end of ''[[PK04|Pikachu's Rescue Adventure]]''. With it, the {{p|Exeggcute}} that had been following [[Misty's Togepi]] around evolved into {{p|Exeggutor}}.

Ash won a Sun Stone in the [[Bug-Catching Contest]] during ''[[EP161|The Bug Stops Here]]'', later using it to evolve a {{p|Sunkern}} in ''[[EP187|Moving Pictures]]''.

Fire Stones played an important role in ''[[EP190|The Stolen Stones!]]'', where they were intended to be delivered to a stadium to be used as a prize for competitors there.

Both the Leaf Stone and Sun Stone appear in ''[[EP239|Whichever Way the Wind Blows]]'' as a demonstration of the [[List of Pokémon with branched evolutions|branch]] in {{p|Gloom}}'s [[List of Pokémon by evolution family|evolutionary line]].

The Water Stone appears in ''[[AG105|Once in a Mawile]]'' and is used by Brock's Lombre to evolve into {{TP|Brock|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 by way of a Leaf Stone prior to ''[[EP057|The Breeding Center Secret]]''.

A Moon Stone appeared in a flashback in ''[[AG060|Delcatty Got Your Tongue?]]'', evolving [[Dr. Abby]]'s Skitty into a Delcatty.

In ''[[DP122|Stopped in the Name of Love!]]'', {{an|Dawn}} gave an Everstone to her {{TP|Dawn|Piplup}} to prevent him from evolving until he wants to.

{{an|Professor Oak}} gave a Water Stone to a wild Lombre in ''[[DP139|A Faux Oak Finish!]]'', while a Dusk Stone was central to the plot of ''[[DP148|Try for the Family Stone!]]''.

[[Ursula]] used a Fire Stone and a Water Stone to evolve her two Eevee in ''[[DP174|Last Call, First Round!]]'', making them a Flareon and Vaporeon, for use in the Grand Festival.

Ash had to find a Thunderstone as part of a scavenger hunt in ''[[BW069|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 Thunderstone nearly came in contact with Pikachu but he jumped out of the way just in time leaving Ash to catch it.

Evolutionary stones do not seem to be required for evolution in the anime as they are in the games. [[List of Pokémon temporarily owned by the Team Rocket trio#Victreebel|James's second Weepinbell]] evolved without a Leaf Stone in ''[[EP261|Here's Lookin' at You, Elekid]]'', though this may just be an example of [[anime physics]]. 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 Thunderstone 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.

==In the manga==
===In [[The Electric Tale of Pikachu]] manga===
In ''[[ET03|Clefairy Tale]]'', {{Ash}}, [[Professor Oak]], and [[Bill]] witness a {{p|Clefairy}} evolution ceremony involving a large Moon Stone.

The focus of the chapter ''[[ET06|To Evolve or Not to Evolve, That Is the Question!]]'' is evolutionary stones. {{an|Misty}} hopes to buy a Water Stone for her {{TP|Misty|Poliwhirl|Politoed}} 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===
In the {{chap|Red, Green & Blue}}, a Moon Stone is first mentioned by {{adv|Professor Oak}} in ''[[PS006|Gyarados Splashes In!]]'' as a rock with a crescent moon-shaped indentation that boosts a Pokémon's power immensely. In the next round, ''[[PS007|Raging Rhydon]]'', [[Team Rocket]] searches for one in [[Mt. Moon]], however it is {{adv|Red}} who finds it. Later on, Red uses this Moon Stone to evolve {{adv|Green}}'s {{p|Clefairy}} during the [[Silph Co.]] catastrophe. Additionally, [[Poli|Red's Poliwhirl]] was able to evolve into a {{p|Poliwrath}} with the help of a Water Stone when they were thrown in the water.

In the {{chap|Yellow}}, {{adv|Yellow}} finds a Leaf Stone in Vermilion Harbor in ''[[PS058|The Kindest Tentacruel]]'', but the Fire, Thunder, and Water Stones are missing. Later, it is revealed {{adv|Giovanni}} gave them to Red so he could evolve and devolve his [[Vee|Eevee]] freely.

In the {{chap|Gold, Silver & Crystal}}, {{adv|Gold}}'s [[Gold (Adventures)#Sunbo|Sunkern]] evolves into a {{p|Sunflora}} in ''[[PS172|The Last Battle VI]]'' because the sun's energy reflected off of the rocks near [[Ilex Forest]] replicated the Sun Stone's effects.

In the {{chap|Ruby & Sapphire}}, {{adv|Ruby}}'s [[Kiki|Skitty]] evolves into a {{p|Delcatty}} in ''[[PS194|VS. Mawile]]'' due to being exposed to one of {{Steven}}'s Moon Stones.

===In the [[Pokémon Diamond and Pearl Adventure!]] manga===
In ''[[DPA19|(Violent) Earthquake! Cyrus's Consuming Ambition!!]]'', it is revealed that [[Mitsumi]] secretly attached an Everstone to [[Hareta]]'s [[Hareta's Empoleon|Piplup]] before he started his journey. She thought Hareta would learn faster with weaker Pokémon, and removed it. Piplup immediately evolved into {{p|Prinplup}}, then into {{p|Empoleon}}.

==In the TCG==
The Moon Stone and Dusk Stone are featured in the [[Pokémon Trading Card Game]] on a {{TCG|Trainer card}} and on Pokémon cards as held items. These held items work in the same fashion as Poké-Bodies, in that the effect the item provides is active whenever the Pokémon is in play. The following is a list of cards named or including Moon Stone or Dusk Stone.

==Trivia==
* Of all {{cat|Pokémon that evolve by evolutionary stone}}, only {{p|Eevee}} and {{p|Gloom}} can use multiple ones; together they can use any of the stones introduced in Generation I or II except for the Moon Stone.
* Only four Pokémon that evolve by stone can evolve using another method: {{p|Poliwhirl}}, {{p|Eevee}}, {{p|Kirlia}}, and {{p|Snorunt}}.
* Only {{type|Grass}} Pokémon evolve using the Leaf Stone and Sun Stone, and all of the Pokémon that evolve using the Sun Stone evolve into pure Grass types.
** Simisage is the only Pokémon evolved via Leaf Stone which is not dual-typed.
* The {{DL|Evolution-inducing held item|Oval Stone}} is sometimes considered an evolutionary stone, and can even be selected to be used like one. However, unlike other evolutionary stones, the Oval Stone does not trigger evolution in any Pokémon when it is used on them. It must instead be held and the Pokémon leveled up, making it an [[evolution-inducing held item]].
* All Pokémon that evolve with the Fire Stone are in the {{egg3|Field}}, and all the Pokémon that evolve with the Sun Stone are in the {{egg3|Grass}}.
* Through {{DL|List of glitches in Generation I|Evolutionary stone glitch|a glitch}} in the Generation I games, Pokémon can be evolved without the use of a stone, provided that the player has sent out the correct Pokémon in the same battle that a Pokémon that evolves using a stone levels up.
* The Dawn Stone induces evolution in only two Pokémon species, {{p|Kirlia}} and {{p|Snorunt}}, the fewest of any stone. Both of them only work if the Pokémon is of a specific gender.
** This also makes it currently the only stone that only evolves Pokémon introduced in a single generation, as Kirlia and Snorunt were both introduced in [[Generation III]].
** Both of the evolved forms from the Dawn Stone gain a secondary type.
** It is also the only stone not to gain a new use in [[Generation V]].
* As of [[Generation V]], the Fire Stone is the only one not used in a three-stage evolutionary line.
* The {{wp|Sunstone|Sun Stone}} and {{wp|Moonstone (gemstone)|Moon Stone}} share their names with actual {{wp|gemstones}}.
* [[Generation III]] and [[Generation V]] are the only generations in which an evolutionary stone is not introduced.
** Both these generations introduced a new Pokémon to evolve with Leaf Stone, Water Stone, and Moon Stone.
* Though six Pokémon families evolve with the Moon Stone, only the four introduced in [[Generation I]] can be readily caught in a {{ball|Moon}}, since Moon Balls can be acquired only from [[Kurt]] in [[Azalea Town]].
* The Leaf Stone is the only evolutionary stone that cannot be sold to the {{DL|Item maniac|ore maniac}} in {{2v2|Black|White}}; this was corrected in {{2v2|Black|White|2}}.
