How To Get Sun Stones in Pokémon Platinum (All Methods)

At the Hotel Grand Lake in Pokémon Platinum
Sun Stone Acquisition Methods
# Method Repeatable?
1 Valor Lakefront—In a wall at the top of a series of terraces to the east of the Hotel Grand Lake (requires Surf and Rock Climb) (hidden) No
2 Mt. Coronet—On a rock on Mt. Coronet’s fourth floor (requires Rock Smash, Rock Climb, Strength, and Surf) (hidden) No
3 The Underground—Potential treasure found in the mining minigame Yes
4 Held item (5% chance) found on the following wild Pokémon:

  • Solrock (Lake Verity, Lake Acuity, Lake Valor, Mt. Coronet, Sendoff Spring, Turnback Cave) (on a DS console with Pokémon Ruby in the GBA slot only)
Yes

The easiest way to get a Sun Stone is by picking one up at the Valor Lakefront. But since this specific location requires Rock Climb, this Sun Stone won’t be available until close to the end of the game.

You can alternatively get Sun Stones much earlier by searching for them in the Underground, but this can take a massive amount of time to produce any results.

Acquiring Sun Stones

Method 1: Valor Lakefront (Step-by-Step)

The easiest Sun Stone you’ll get in Platinum is found at the Valor Lakefront. You’ll find it on a terrace directly east of the Hotel Grand Lake.

You will need Pokémon that can use Surf and Rock Climb outside of battle in order to find this Sun Stone. So you’ll first have to beat Leader Candice in Snowpoint City and receive the Icicle Badge from her.

With the prerequisites out of the way, start by Flying to Pastoria City and heading east from the Pokémon Center.

Method 2: Mt. Coronet (Step-by-Step)

There is another Sun Stone hidden on a rock deep within Mt. Coronet. Like the Sun Stone at the Valor Lakefront (Method 1), you will only have access to this one after receiving the Icicle Badge.

You will also need Pokémon with the following Hidden Moves:

This will be an arduous journey, so you might also want to bring healing items, Max Repels, and Escape Ropes just in case.

The entrance to Mt. Coronet that you want to use is northeast of Oreburgh City. So Fly to the Oreburgh Pokémon Center and head north along the main road.

Method 3: The Underground (Repeatable)

You can get Sun Stones much sooner in the game if you commit to searching in the Underground for one.

However, this is a highly unreliable method. And it can take several hours of playing the mining minigame to produce results.

But if you need one earlier in the game, this is probably your best option.

To start searching for Sun Stones, dig down to the Underground by using the Explorer Kit. You will receive this from the Underground Man in Eterna City.

When you have control of your character, head for one of the glittering areas shown on the map.

Digging into bulging walls will begin a minigame.

Alternate between your hammer and your pickaxe to dig as many treasures out of the wall as possible before the wall comes crashing down from the repeated banging.

  • The hammer breaks more rocks and dirt per hit, but causes the minigame to end quicker.
  • The pickaxe is weaker, but more precise and less damaging to the wall.

Every time you mine a new spot in the Underground, there is only a 20% chance that a non-sphere item will be hidden beneath the rocks and dirt.

There are close to 50 different non-sphere item types that can be uncovered. Because the odds of finding a Sun Stone in a single minigame are pretty low, you can expect to spend a while searching for one.

Remember to send your items aboveground by selecting them in the Treasures sub-menu.

Method 4: Held Item on Wild Solrock (Repeatable)

Another repeatable way to farm Sun Stones is by taking them from wild Solrock.

There’s a catch to this though:

You will only find wild Solrock by playing the game on a DS or DS Lite console with Pokémon Ruby in the GBA slot.

With Ruby in the GBA slot, you’ll be able to find wild Solrock at:

  • Any of Sinnoh’s major lakes
  • Mt. Coronet
  • Sendoff Spring
  • And Turnback Cave

This method can also take a while. Solrock has only an 8% encounter rate, and a mere 5% chance of holding a Sun Stone.

However, you can greatly speed up the process of farming Sun Stones by building a designated item farming team.

These special teams use Pokémon with the Abilities Frisk and Compoundeyes to both increase the odds of finding items and identify any items being held.

If you’re using an item-farming team, the Compoundeyes Ability will raise the odds of a Solrock having a Sun Stone from 5% to 20%.

Frisk will also alert you to any items the foe is holding, saving you from wasting time on guesswork.

After discovering a Solrock with a Sun Stone, either use a stealing move (like Thief or Trick) or catch the Solrock to obtain the item.

Then just end the battle however you prefer—you will keep the Sun Stone even if you flee.

Sun Stone Details and Uses

The in-game description of the Sun Stone / Pokémon Platinum
The in-game description of the Sun Stone.

In Pokémon Platinum, the Sun Stone is used to evolve the following two Pokémon species:

Sun Stone Evolutions
Species Evolutionary Form
Gloom Bellossom
Sunkern Sunflora

To use a Sun Stone, simply select “Use” from the Bag and choose a Pokémon to use it on.

Bellossom

You can use a Sun Stone on Gloom to make it evolve into Bellossom.

A newly-evolved Bellossom.

Bellossom is one of two possible evolutions of Gloom, the other being Vileplume (via the Leaf Stone).

Both Bellossom and Vileplume are nearly identical in stats, Ability, and movepool.

The biggest difference between them is that Vileplume has a marginally higher Special Attack stat, while Bellossom’s Special Defense is slightly superior.

To help make Bellossom more viable in battle, you’ll want to put its Chlorophyll Ability to work. Chlorophyll will double Bellossom’s miserable agility to a base stat of 100 in harsh sunlight, which still isn’t astounding, but at least allows it to be competitive.

If you can factor Sunny Day into Bellossom’s strategy, Bellossom can be a hard hitter that’s quick on its feet; otherwise Venusaur or Roserade would be a better option.

Sunflora

You can use the Sun Stone on Sunkern to make it evolve into Sunflora.

There’s no getting around it:

Sunflora is terrible.

It has a base Speed stat of 30, rendering it as slow as Snorlax and Steelix. And the rest of its stats don’t fare much better.

In fact, its only decent stat is its Special Attack – which still isn’t high enough to justify how crippling the rest of its stats are.

Even with the Chlorophyll Ability it’s too slow to be competitive.

Generation IV introduced Sunflora to another Ability: Solar Power, which increases the user’s Special Attack by 50% in harsh sunlight. This was possibly added in an attempt to even its odds in battle.

However, Solar Power subtracts ⅛ of Sunflora’s health at the end of every turn that harsh sunlight lasts. It’s almost like Sunflora was set up specifically to fail.

You should get Sunflora for the Pokédex entry, but trying to use it in battle is an exercise in futility.
