The Sun Stone Pokémon GO evolution item is one of several special evolution items used to evolve specific Pokémon that cannot evolve through Candy alone. While it’s less common than standard evolution methods, the Sun Stone Pokémon GO item is essential if you’re looking to complete your Pokédex or evolve certain Grass-type Pokémon.
If you’re wondering how to get a Sun Stone, which Pokémon need it and whether it’s worth keeping, here’s everything you need to know.
What Is a Sun Stone in Pokémon GO?
The Sun Stone Pokémon GO item is a special evolution item that allows certain Pokémon to evolve when used alongside the required amount of Candy.
Unlike Evolution Stones in the main series Pokémon games, the Sun Stone isn’t found in the wild. Instead, it must be earned through gameplay, making it one of the rarer evolution items available.
Once you’ve obtained one, it remains in your Item Bag until you use it.
Which Pokémon Evolve Using a Sun Stone?
Only a handful of Pokémon currently require a Sun Stone Pokémon GO evolution.
| Pokémon | Evolves Into | Additional Requirement |
|---|---|---|
| Gloom | Bellossom | 100 Oddish Candy + Sun Stone |
| Sunkern | Sunflora | 50 Sunkern Candy + Sun Stone |
| Cottonee | Whimsicott | 50 Cottonee Candy + Sun Stone |
| Petilil | Lilligant | 50 Petilil Candy + Sun Stone |
As new Pokémon are added to Pokémon GO, Niantic may introduce additional Sun Stone evolutions in future updates.
How to Get a Sun Stone in Pokémon GO
There are several ways to obtain a Sun Stone Pokémon GO item.
| Method | Chance |
|---|---|
| 7-Day PokéStop Spin Streak | Best chance |
| Special Research | Occasionally available |
| Timed Research | Event dependent |
| Pokémon GO Events | Sometimes rewarded |
| Collection Challenges | Selected events only |
For most players, the easiest way to obtain a Sun Stone is by completing the seventh consecutive day of spinning a PokéStop or Gym.
Although there’s no guarantee you’ll receive one every week, this remains the most reliable permanent method.
How Rare Is the Sun Stone?
The Sun Stone Pokémon GO item is considered an uncommon evolution item.
Because the 7-day streak can reward several different evolution items, receiving a Sun Stone depends on chance. Some Trainers may receive one quickly, while others may need several weeks before one appears.
Fortunately, once you’ve evolved every Pokémon that requires one, you’ll rarely need large numbers of Sun Stones.
Can You Buy a Sun Stone?
No.
Unlike Premium Battle Passes, Incubators or storage upgrades, the Sun Stone Pokémon GO item cannot be purchased from the in-game Shop.
Instead, it must be earned through gameplay by completing streaks, participating in Research or taking part in certain events.
Should You Keep Extra Sun Stones?
Yes.
Even if you’ve already completed every current Sun Stone evolution, it’s worth keeping a few spare Sun Stone Pokémon GO items.
Niantic regularly introduces new Pokémon and regional evolutions, meaning additional Sun Stone evolutions could be added in future updates.
Keeping one or two spare evolution items can save you from waiting weeks to find another if a new evolution is introduced.
Sun Stone vs Other Evolution Items
Pokémon GO features several different evolution items, each used for specific Pokémon.
| Evolution Item | Used For |
|---|---|
| Sun Stone | Bellossom, Sunflora, Whimsicott, Lilligant |
| King’s Rock | Slowking, Politoed |
| Metal Coat | Steelix, Scizor |
| Dragon Scale | Kingdra |
| Upgrade | Porygon2 |
| Sinnoh Stone | Multiple Generation IV evolutions |
| Unova Stone | Selected Generation V evolutions |
Collecting these items is essential if you’re aiming to complete your Pokédex.
Is the Sun Stone Worth Using?
Absolutely.
The Sun Stone Pokémon GO item is required for several Pokédex entries and remains one of the game’s most important evolution items. Whether you’re evolving Bellossom for the first time or finally adding Lilligant to your collection, you’ll eventually need a Sun Stone.
Since they aren’t available in the Shop and rely on gameplay rewards, it’s usually worth holding onto any Sun Stones you receive until you’re certain how you want to use them.
Is the Sun Stone Pokémon GO Item Worth Keeping?
Yes.
Although you won’t use a Sun Stone Pokémon GO item as frequently as Poké Balls or Berries, it’s an important evolution item that every Trainer should keep in their inventory. With several Pokémon requiring one to evolve, and more potentially arriving in future updates, having a spare Sun Stone ready can save you time when the next evolution becomes available.
