You cannot buy but you can teach your pokemon new moves in exchange of shards.
The color shards you can find in Pokemon Platinum are Red, Blue, Green, and Yellow Shards.
there is a man in the resort area who trades shards for moves you will have to have a pokemon that learns rock climb though. hope this helped
Go to the underground and dig in the walls to find shards. It may take a while but you can get TM's from someone. They are sunny day, rain dance, sandstorm.
Uh??? There's no such thing!
fossils, shards, stones, plates, spheres
Shards can be found underground commonly. So you can look there if you want. There might be a code too but I wouldn't know. I hope it helped a bit!
shards can be used to trade with other people. in return, they may teach your Pokemon moves. there are 3 move tutors in Pokemon platinum that will teach your Pokemon moves in exchange for shards in a specific color.
You can trade them to the move tutors so that your Pokemon can learn different moves.
yo cant get it BUT you can go to the man in the way from hearthome to pastoria and he will teach it to a Pokemon for shards.
Sadly, no. You can get stones in the underground. Just keep digging.
