Can you trap the souls of monsters you have summoned into a soul gem in Skyrim

Black Soul Gems are exactly like Grand Soul Gems - with one significant perk:

They can trap humanoid souls.

Regular soul gems are restricted to creatures and undead only.

But black soul gems?

Tired of the blacksmith sending out hits on you? Kill him, trap him in a black soul gem, enchant him into a ring, and then sell the ring back to his wife. Justice is served!

A captured soul will be put in the smallest available soul gem that will hold it. So if you capture a lesser soul, and you only have a grand soul gem available, it will be automatically put in the grand soul gem. If you have a empty grand and lesser soul gem, a lesser soul will always be put in the lesser soul gem.

If by chance you accidentally fill a larger soul gem with a lesser soul, you can drop it to the ground and pick it back up. Dropping soul gems to the ground causes them to lose the stored soul and this prevents the waste of larger gems filled with smaller souls.
