What breed are these chickens?

[LunaMoriarty]

I obtained these two together late last fall and I am still confused about what breeds they are.

This is Nymphadora.

This is Artemis.
Nymphadora (or Nymph for short) Is the only chicken I have with spurs. She looks allot different from Artemis so I don't know for certain if they are the same breed. Artemis had an emerald green shimmer to her feathers which is gorgeous. She is also the most gentle one of the flock. I love her to pieces. I love all of my chickens to pieces!
If anyone can help me identify their breeds I would be greatly appreciative.

First hen is a Black Sex Link. Second hen could be a Black Australorp.
