Picked this up from the river on the way into Yellowstone, from a gravel bar. It was half buried and a pain in the butt to get unstuck. I couldn't resist that incredible green but I have no idea whether it will polish or what it is. It was a major decision to pick it up and bring it back, especially since this was relatively early in the trip! But it came back. It is now 2 huge green rocks because it had a crack in it so I dropped it on the sidewalk & it broke!   Thanks for lookin'! |

Good-Looking Rock...s,
This stuff looks like it should polish up very nice!

Looks just like the rock that I got from Ebersole's called Prase.  Tami |

Hey Tami, does your prase take a polish? I keep picking up green river rocks and they hardly ever polish. My fear is that this one is more of the same. Doc, I don't think it is aventurine, based on the fact that I picked up a big piece of aventurine last summer (I have finally gotten ID's on it so that I'm sure) and this rock isn't like that one -- that one had a very uniform texture and was very tough, while this one is more textured and has a lot of crystal in it. The photos make it look even better than life. Obviously I thought it was worth it to carry it thousands of miles in the back of a car -- that thing was bigger than a bowling ball! All I can do is try to tumble some, if it won't do anything it will still make a great yard rock -- what an amazing color it is!
Just another thing to annoy the dealers with, in a couple weeks at the next local rock show.

Hey puppie, it really looks like oxidized copper in the rock. Try a little ketchup(the acid will remove the oxidation) or copper cleaner on a spot of the green and see if it removes the green color. This will work if the copper has just infiltrated the space between the crystals. It won't come off if the copper has chemically combined with another mineral. Copper will sometimes be found in Quartzite which is made up of a mass of small crystals instead of one large crystal like Quartz.

I don't know if the prase will polish or not I haven't had time to break it up yet. It has been way too hot here to do something like that and I can only do that outside.

Sure looks like amazonite.It's a greenish/bluish (aqua?) feldspar related to the more common pink-colored variety. It's usually found in areas with lots of granite or other igneous rocks.

It also looks like it could be malachite. A green copper ore related to azurite (the bluish variety) and turqoise.

I have some small rocks like that and I was thinking they were amazonite but not sure. Havent tumbled them yet cause didnt want to put them in with the wrong rocks.
I have some malachite and its a darker green unless malachite comes in different colors.

Malachite tends to layer and swirl. Doesn't look like Malachite to me.
I'd lean more towards aventurine like Doc.

Puppie, The mysterious green roxk revealed! It is a wonderful specimen. Have fun with it. csroc HA! Was it worth the wait? There's a thing about green rocks. I find them a lot in river rock and such, in the west. Also on the coasts. A lot of it doesn't want to polish. Aventurine is the one I'd rule out since I've found it before and this is different. If anybody thinks they can tell I'd be glad to send you a piece. |

Ron, I haven't done the ketchup test yet. I want to do this when I'm awake and paying attention, that's really interesting!
