Well, not sure if I can do this picture thing but I'm going to give it a shot. I do have quite a few things to identify if you guys don't mind. Like I said, I'm new to this and I don't have a clue what anything is  This first one is the back of a piece that I started to work on. One of my first 3 pieces, it's not done yet but I left the back rough and only polishing the front and sides  |

Okay, I'll take a stab at some of them.
I would call the first two pics lace agate.
The third pic also looks to be some kind of agate.
4th pic... agate? jasper?
5th pic... I'm thinking jasper, mainly because of the orbs.
6th pic... I'm guessing milky quartz with a few inclusions of black biotite mica.
7... no clue.
8... looks like calcite to me.
9... might also be calcite?
10... looks like quartz, with some red colouring either from feldspar or more likely from impurities in the quartz.
next few... no clue.
very last pic... looks like another agate, maybe a moss agate?

thanks a bunch
The 8th one I found with the petrified wood and it has all the lines like the pet wood. One of the old guys on the trip said it may be opalized wood? could that be right? Again, I have no clue
I dipped all the stuff in water so some of them look a bit off. Should I take pics without the water on them?
The first 2, the lady told me they were mexican marble but again, I have no clue and have not been able to find anything on such a thing

I don't think so, since I don't see any flash or fire like you get with opal, but maybe someone has a better idea here. You can certainly differentiate it between my guess of calcite (Mohs 3 hardness) and petrified wood (usually Mohs 7 hardness). Take a piece of glass (mohs 5.5) and see if it can/can't scratch the mystery rock...glass will scratch calcite but not petrified wood (and I think not opalized wood either). Mexican marble?... I wonder if this is maybe onyx then ... onyx comes from Mexico and has banding like that, but it is softer than agate. Glass won't scratch agate, but it might scratch onyx... you'd have to do a google search on "mohs onxy" to find out. |

#7 - Howlite??? Just a guess
I'll have to go with rollingstone on the rest

I just tried glass on that piece in pic 8 and it's not touching it. If I look at it really close I can see stripes in it..........I'm going to try to grind it down a bit to see if that helps to see what it is

Fox, not all agates are hard. There are some pretty soft ones out there ... like Rosetta lace agate... VERY soft

alright, here's 8 again but I ground it down a bit in one spot. The first one is taken without sun, the second in the sunlight   |

Hi, new here. Photo's could be:
The first two look like Rhodocrosite to me.
Probably a B grade due to the black band at the top.
3. An agate.
6. + 7. possibly green moss agate.
9. Petrified wood.
12. + 13. look like Jasper
14. Agate (moss)
Possibly!

The rock you think is opalized wood one way to tell is by weight, opalized wood isn't as heavy as pet wood, another way to check is to do the scratch test. Opalized wood isn't as hard as pet wood.

#8 could be Opalized wood- but usually Opalized wood looks more like the last pic. I have a chunck of common opal (NO FLASH) that looks a lot like #8 so I would guess that maybe it is just common opal- Still they all look cool- BTW if possible always Photo wet- shows color and texture soo much better (IMHO)
