Names for six levels of gem qualities?

Names for six levels of gem qualities?

For my latest project I'd like to use gems to modify items, much like Diablo II did. I'd  asume that 5 or 6 level of gem qualities are enough, if they are scaled well.

Now the tricky part is, how to name them. I assume that "perfect gem" and "flawless gem" can hardly be a copyright issue, since those are quite common descriptions?

English isn't my mothers tongue, and I feel a bit uncertain about the lower ranks of gems. What do you think about these?

flawed [ruby], simple [ruby], average [ruby], fine [ruby], flawless [ruby], perfect [ruby]

Where the [ruby] is, the real name of the gem would go in the game.
