A small green shard. It appears to be a fragment of some sort of implement made long ago.

No effect. In Diamond and Pearl, trade ten for a []{move:hail} [TM]{item:tm07} in the house midway along the southern section of []{location:sinnoh-route-212}. In Platinum, trade to [move tutors]{mechanic:move-tutor} on []{location:sinnoh-route-212}, in []{location:snowpoint-city}, and in the []{location:survival-area}. Eight shards total are required per tutelage, but the particular combination of colors varies by move. In HeartGold and SoulSilver, trade one for an []{item:aguav-berry}, a []{item:lum-berry}, and a []{item:rawst-berry} with the Juggler near the Pokémon Center in []{location:violet-city}. In HeartGold and SoulSilver, trade one for a []{item:durin-berry}, a []{item:hondew-berry}, and a []{item:wepear-berry} with the Juggler near the []{location:pal-park} entrance in []{location:fuchsia-city}.
