Where to find Rainbow Shard in Emerald?

[Eramemory]

Hi, I'm new to the game... I adore the Advent Touhoumons ever since I read the awesome Advent Cirno series, but I can't find any Rainbow Shards so far I'm at the 6th gym; is there somewhere to attain one in the game?

You have two options- either catch a boatload of CYukaris in the Safari Zone and hope one of them has a Solar Shard (5% chance), or wait until you have access to the shard traders' house (out in the ocean west of Mossdeep). You'll need Red UFOs for the latter but those are fairly common if you search the ocean, and can be found on certain UFO characters sometimes.

in addition to the aforementioned methods, you get a free solar shard in the mossdeep space center.
