Identity Helpneed id plz. im new here so i have several id requests

14th Apr 2014 05:29 UTCSandy sandy

I want to thank everyone in advance that takes the time to reply I really appreciate it I have been trying to ID the stones for quite some time and I just about gave up

Please correct my name suggestions for some of the stones.

The first picture is not sharp enough, and as it looks like a sulfide (or an oxide) the streak and the hardness are needed. The other ID's look correct.

We need a better picture of the first one. It may be a sulfide mineral of some kind or perhaps specular hematite.

Black shiny rock kinda heavy close up pictures with and without flash does anybody know the name of it?

If at all possible try the hardness test (search Mohs scale if you don't know what I mean) and tell us the hardness. Also try the streak test on unglazed porcelain, with the metallic minerals it can be easy to identify by color of the streak.

First one could be sphalerite but difficult to say for sure, could be a lot of other things as well. I would suggest a specific gravity test if it looks like it is just one mineral, also hardness and streak would help. The second amethyst and the last as noted, lepidolite (assuming it is soft).

The first specimen might not even be a mineral. I'm looking at it thinking maybe a gabbro or amphibolite, but a more detailed photo would help. The other two photos seem spot on: amethyst and lepidolite.
