Currently, I'm enchanting a Glass Bow (Exquisite) with Fire Damage. I have a Grand Soul Gem and a Petty Soul Gem available.

When selecting the Grand Soul Gem, the weapon has the following stats:

  • Damage: 30
  • Weight: 14
  • Value: 1702
  • Burns the target for 43 points. Targets on fire take extra damage.

When using the Petty Soul Gem, these are the stats:

  • Damage: 30
  • Weight: 14
  • Value: 1372
  • Burns the target for 43 points. Targets on fire take extra damage.

I've also noticed that the charge level of the weapon is just slightly less.

Since I plan on actually using this weapon, I really have a hard time seeing any worthwhile difference here. The only changes are:

  • Value is lowered. (Not relevant to combat.)
  • Weapon is slightly less charged. (Very small difference, and easily resolved by charging with another low-level gem.)

I could see using the higher gem perhaps if I wanted to go straight to market with this weapon. But other than that, is there really any point in using a higher-level gem to enchant weapons you actually plan on using?

The difference is how big the maximum charge will be. So, if you use the petty gem, you will have to recharge the weapon all the time. If you use the grand gem (assuming it contains grand soul), you will have to recharge it only rarely.

Source: Skyrim:Enchanting on UESPWiki:

The type of soul gem affects the amount of charges on a weapon or quality of the enchant on apparel.

    Thanks. This is a significant difference that is not well reflected in the "gem selection" phase of enchantment. You can only see this in the "spell selection" bit.

The gem doesn't matter.

The soul inside the gem does.

You can get a lot more out of a grand soul than you can out of a petty soul -- many more charges (attacks) for weapons, much better stats from armor. A gem can also fit in any soul its size or smaller.

I'd suspect, from the information given in the question, that your grand gem has a lesser or common soul in it, so you're not going to see much difference between that and your petty soul gem with a petty soul in it.

    To add onto this if you have a larger gem with a smaller soul in it (ie. grand gem with a petty soul) you can clear the soul out of it by dropping the gem on the ground and picking it back up again.

The Soul affects how much charge the enchanted weapon has for example- A petty soul in a petty soul gem will have the same charge as a petty soul in a common soul gem. The soul gem them selfs show what kind of size soul it can hold up to for example- common soul gems can carry common to petty souls but cant carry grand or greater souls.


sorry but this is all incorrect, on skyrim when you pick a grand level soul gem it dont change the charges available, as to a petty soul gem, before selecting a soul gem u have a slider that seems to have a predetermined amount of charges/power a weapon can have, you can sacrifice power for charges or visa versa, but the only thing that changes with the gem is the weight of the weapon and the value all irreverent to combat.
