What kinds of stones are these?

Question

I'm starting a small jewelry "business" for myself while I'm at college, just for some extra cash. My brother gave me his rock collection a while ago, but I have no idea what kind of stones these are:

The earrings (A) are quartz, I believe. Also, I'm pretty sure B is hematite. Can anyone else identify the others? Also, are there any really good sites on the web where I can find an easy way to determine what kind rocks I have? I'm thinking something with pictures and reliable to someone who is brand new at categorizing rocks. Thanks!

Answer 1

You are correct about B.

Be aware that ID'ing rocks and minerals from pictures is very hard, so I may not be correct.

Also, rocks and minerals are not the same thing.

C) Looks like quartz with perhaps some rose quarts inclusions or potassium feldspar ones.

D) I cannot tell due to the glare. Perhaps tiger iron, agate, or a jasper.

E) Looks like blue quartz or a very blue piece of sodalite

F) Unakite

G- M) These all look to be some sort of jasper or other types of microcrystalline quartz. A few of the colors look artificial.

If you are at college, I bet there is an Earth Sciences department who could help you much more than a glared pictured shown to people on the Internet.

***Anything artificially colored is most likely some sort of microcrystalline quartz. You can try webmineral.com or just web search for mineral and rock identification.
