Diamond

[dawnhvr]

have quite a large collection that I love and have no clue what they are.

I did buy a diamond tester and recently was going through my finds to see if anything was worth keeping.(I have sooooooo many) my sunroom is starting to look like a small mine. I have smashed a lot with a hammer while going through a geode faze and while checking this rock I got this.........

Diamond testers are useless for this hobby, sorry. You have some sort of rock. A closeup photo might help, but it's not easy to ID stuff from a photo. Try joining a local rock and gem club, you'll learn a lot!

Cool, but...... I'm not sure how they react on other/regular rock. I know corundum will register a 4 on some.
Did you say these rocks came from beside the Arkansas diamond crater mine?
Location of find can be telling, as well. Not knowing location or source Diamonds have been found, in odd places.....
I don't have much else than that. Well this......

I LOVE those little acorns and I have seen them somewhere before! You make those?

The above posts are right. Diamond testers are to be taken with a pinch of salt. (or rather, a barrel of salt)

Learning a few basics like hardness tests, streak tests etc will be much more helpful. Also asking in this forum isn't such a bad choice.
