There around the hunters house west from mossdeep city. You need the HM dive to find them.
in lilcove in the cave is the green shard
You can trade them for evolution stones eg. yellow shard = thunderstone
nowhere, find a green shard and bring it to the shard hunter near mossdeep city... he will trade it for a leaf stone
There is a hunter west of Mossdeep city that will take special shards like the red shard trade your shard for a evolutionary stone so the red shard will give you a fire stone.
The moon shard was in a Pokemon movie, and it was apparently given out as a Promo item, along with the sun shard.
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.
Blue Shard- Route 124; Wild Pokemon. Green Shard- Route 126; Wild Relicanth. Red Shard- Route 124; Wild Pokemon. Yellow Shard- Route 126; Wild Pokemon.
Red shards are found underwater.
to get all the stones you need, first go underwater by using the HMO8 DIVE.. teach it to a water Pokemon then go to the sea behind the the mossdeep city, then go to a part where the water has a color of dark then use dive at the top of it then search for a GREEN SHARD,RED SHARD,YELLOW SHARD or BLUE SHARD.. then exchange that thing to a house behind the mossdeep city then talk to the man inside the house then you have it..
Yellow Shards and the other color shards are used for trading with NPCs for items or moves. For example in Pokemon Ruby, Sapphire and Emerald they are the main source of evolution stones.
give the shard hunter a yellow shard found under water near mossdeepcity and sootoplis
oh please you have to get a green shard then give it to some guy poacifdlog
