In the Pokémon game series, Water Stones are precious items that allow you to evolve certain Water-type Pokémon. Usually, Water Stones (like other elemental stones) are hard to come by - often only a few can be found in each game. In Pokémon Emerald, there are two ways to get a Water Stone: you can get one in exchange for a Blue Shard at the Treasure Hunter's house, or there find one on the Abandoned Ship.
Part 1 of 3: Getting a Water Stone from the Treasure Hunter
Step 1. Get a Blue Shard
This method uses the shard dealer (also known as the Diving Treasure Hunter) to exchange a Blue Shard for a Water Stone. To get started, you need a Blue Shard. These fairly rare items can be found in a number of places, including:
- Under rocks in a number of places, when using Dive to use underwater roads (such as Route 127, 128, etc.).
- Possibly after you defeat Wild Clamperl.
Step 2. Go to the house of the Diving Treasure Hunter
Once you have a Blue Shard you can go to the Diving Treasure Hunter. You can find his house on an island on Route 124 (near Mossdeep City.)
Step 3. Talk to the Treasure Hunter
He will offer to give you a Water Stone in exchange for your Blue Shard. If you agree to this transaction, you will have a Water Stone from that moment on!
Part 2 of 3: Getting a Water Stone from the Abandoned Ship
Step 1. Go to the Abandoned Ship
Another method of getting a Water Stone doesn't use Blue Shards at all. Instead, you'll find this Water Stone in the wrecked ship called the S.S. Cactus. You can find this ship on Route 108 (in the lower left corner of the world map).
You need a Pokémon that knows Surf to get to the Abandoned Ship. You also need to know Dive to get the Water Stone - the stone is not underwater, but it is in a part of the ship that you can't reach without going underwater
Step 2. Enter the ship and go to the part that is deep underwater
Once you arrive at the Abandoned Ship, follow these directions to navigate your way through the ship's labyrinthine interior:
- Walk up the stairs and go through the first door you come across.
- Go up, then to the right and then down the stairs at the top right.
- Go straight down to the door directly below your position.
- Walk to the waterhole.
Step 3. Use Dive to explore the depths of the ship
As noted above, you'll need a Pokémon that knows Surf and Dive to get through this next section. Use your Pokémon's Surfing Power at the edge of the waterhole to go swimming. Then go down and use Dive to get underwater to the next part of the ship.
You can find Dive (HM08) in Mossdeep City. You need the Mind Badge to use it
Step 4. Swim underwater until you reach your goal and then surface again
Use the following clues to get through the part of the ship that is deep underwater:
- Go left and through the door of the hallway, top left.
- Go a little way into the room and then surface.
Step 5. Get the Water Stone, which is behind the third door
Once you get out of the water, walk to the right and go through the third door. You should see two item balls in the room you enter next. One top right and one top left. The one on the left contains the Water Stone.
Part 3 of 3: Using your Water Stone
The Water Stone allows you to evolve certain Water-type Pokémon - without it, these Pokémon will not evolve, even if you constantly level them up. See the list below to find out which evolutions in Pokémon Emerald require the Water Stone.
|Base Pokemon||Evolution to…|
- Note that the Water Stone is consumed when you evolve a Pokémon with it. Since it is difficult to get such stones, you should think carefully about which Pokémon you use them for.
- You can also find the Scanner on the Abandoned Ship - to get to it you need Dive.
