1-?. 2-quartzite? 3-jasper? 4-?
1 and 3 are really nice in any case. Find them yourself?

#1 and #4 may be ricolite varieties. I'm used to seeing more banding in ricolite but the colors are right for this serpentine type material. Or they could simply be green quartzite.....Mel

Saskrock- My grandparents picked them up (along with two more 5 gallon buckets worth) a few weeks ago while they were in NM.
sabre- Are they good for tumbling?
Thanks for the help! =)

Any that are quartz hard ( can't be scratched with a knife blade) should be fine for tumbling. Serpentine is usually a mixed hardness material so does not tumble well. If it's green quartzite though, it'll work up well....Mel

Thanks! I'll have to sharpen my knife and test them tomorrow. I was just informed though, that these came from Silverton, Colorado instead of NM.

#1 almost looks like some sort of jade, but hard to tell

I tested #1 and a knife blade wouldn't scratch it but I don't know how hard jade usually is.

Jade is usually between 6-7, typically 6.5. Best way to tell is specific gravity...jade will usually hit between 2.9 and 3.1
