Identify skins by name

In most cases, when an item of one name can have multiple skins, I can figure out which is which.

But in the case of earth staves, I can't, and I can't find pictures.

What's an Orrian skin? What's an obsidian skin?

Thanks!

as far as i know there are at least (5) skins labeled "Earth staff"
1) looks like a long, standard earth wand
2)looks like staff of orr, from sanctum cay mission (orrian skin) - has a diamond shaped floating stone at the tip
3) Factions skin - looks like it has a spiral or fingerprint on the head
4)Old earth staff skin - looks like a rock crystal /bluish in color similar to standard earth staff appearance, but without defined handle area
5)Nightfall skin - has 3-4 floating rocks on the end - gray color

- i will look for pics and add them if i find

EDIT: found pics of all five at : http://gw.gamewikis.org/wiki/Earth_Staff

Thanks! That seems obvious, but I was being too precise in my searches.

So obsidian = Orrian. Got it.

I'm pretty sure all of mine are common skins.
