See a gem's upgrade?

I'm a noob and sorry if this is a stupid question... I have looked online and have been unable to find an answer and asked in game as well to no avail. When leveling up a gem, is there a way to see what the new damage/mana cost/etc is before upgrading? I seem to only be able to see its current state and not what I gain from leveling it up. I'm a nerd and I like such things.

Thanks.

edit: For the purpose of your question, no, you cannot view it ingame currently. The link I provided will give you a list of most/all gems and most/all of their respective level up bonuses.

Thanks for the quick response. I can't view the link in my current state but are all the levels 'equal'? In other words, every time you level gem x it's damage is increased by 3% for example? Or will it sometimes be 4% or a different upgrade entirely?

Yeah, you can generally assume they're equal. An aura gem which improves your armour by 32%, will improve it by 33% on it's next skillup, then 34% and so forth. Some other gems are set damages, but you get the idea.
