I figure he's referring to 【水精の卵】.

It's a water blade, so I'm not sure it's "Crystal Origin" or whatever the ability is.

We'd need to know what the ability actually does to make any sort of judgement on that.

In the meantime, as was said in the comments...if you read them separately (like the author loves to make us do, sometimes, heh)...then it would be "Water Spirt/Fairy Origin" or something like that (not Egg, I'm guessing...which is the other meaning for the last kanji).

I'd suggest that it's that way, instead of Crystal...since unless the ability says "This is has something to do with crystals"...it's better to use the context and say it's meant to be the water stuff instead. ^^
