To get stones in Pokemon ruby you have to go to the shard hunter (surf left from Mossdeep). He will trade you stones for shards. You have to find shards by diving in the waters around route 124 (right around his house). You can use your itemfinder to find them, but they're usually just in the spots that are lighter than the surrounding area. Shards can also be found on Pokemon in the wild. The easiest way to get them is to dive, find Pokemon in the grass, and then use the move Thief on them, which will steal whatever they're holding.
Relicanth- green shards
Chinchou- yellow shards
Clamperl- blue shards
Corsola- red shards
The type of stone you get from the shard hunter corresponds to the shard's color. For example, green shard=leaf stone, red shard=fire stone, etc.
