u can get it from shard hunter near mossdeep
On the abandoned ship.
Water Stone...Well... If I remember correctly, there's a guy who's willing to trade a water stone for a Blue Shard. Oh! And you can find one on the Abandoned Ship.
Abandoned ship, Rm. 2, while trying to get the Scanner after diving.
To get a Water Stone in Ruby, Sapphire & Emerald. You can find one on the Abandoned Ship. Additionally, you can get many of them from the treasure hunter near Mossdeep City by trading him Blue Shards.
You can find it on the Abandoned ship and on route 124 or exchange A Blue Shard to the Diving Treasure Hunter.
You can't get Lucario in Ruby, Saphire or Emerald. Diamond, Pearl and Platinum only. sorry....
from trading a blue shard with hunter on island near mossdeep. There is one you can find in the abandoned ship.
I have heard there is one on the Abandoned Ship, but I'm not sure. You need to use dive, find a clamperl, use thief or covet on each until you find a blue shard. Then, go to the Collector in Mossdeep and trade the blue shard for a water stone.
There are two ways of getting a water stone: 1) On the abandoned ship there is one inside a pokeball. 2)Dive to the bottom of the sea and find a blue shard then take it to the shard hunters house and he will trade you one for your blue shard. Hope this helps.
go underground and keep digging till u find a water stone or a fire stone
The water stone is found in the Solaceon Ruins. Go into all the chambers with a rock in the middle of them. You will find a Water stone. Also, in the Solaceon ruins, you can also find a Thunder stone and a Fire stone.
