Yup! maybe we should show why though, so we can see reasoning. So, why?

I like to think of Malachite being "fuzzy" (or circular, ringed, and very smooth) and green. Azurite is blue and "rocky" and it comes along with Malachite, just like the picture.
Identify both and describe how you arrived at your conclusion.

Ummm the first would be apatite because... well, heres my thought process --> 1) if it's blue it's either azurite, apatite, celestite, fluorite, or tourmaline 2) I ruled out azurite because azurite is usually opaque where this mineral is translucent 3) celestite, fluorite, and tourmaline can't possibly be it because of their cleavage and crystal habit 4) therefor it's azurite
I did the same process for the second but sodalite just popped into my head because sodalite is opaque and dark blue in color

1st image is not azurite.
2nd image was correct in your response.
