I'd really like the help of the rest of you here (the experts) You know, if you don't use it (which I haven't in years) you do lose it I think I know what it is, but before I even say, I'll wait to see what you all have to say I got this a few years ago from a guy that sells all kinds of stuff out of his garage. He's a garbage man (literally). He had a few rocks one day and I went CRAZY when I found a huge museum quality piece of water melon tourmaline. It was bigger then this rock here (But, that's another story! Later ;D) Anyway, here are the pics... Attachments:

It's hard to tell just from a picture, but it kinda looks like adventurine. If it is, it's a darn fine piece!

Hi Laurie, thanks for responding! I thought it may be aventurine, but am unsure. I was looking at pictures of aventurine on line, but like you say, it's so hard to tell from pictures. Is aventurine somewhat or have a semi transparency to it though? Like around the thinner areas, I thought aventurine may...but, I dunno  I'll take it to my mothers, have her take a look and we'll look in her books. I told her about this forum. Now, "she's" the real rockhound addict! (the apple doesn't fall too far from the tree though  ) I'm sure she'll come by here... |

I also think it is aventurine, and here's a good photo/closeup: en.wikipedia.org/wiki/File:Aventurine.jpgDoes the surface look similar to this picture? Aventurine can be "translucent", because it is a chalcedony. "Transparent" is more like clear optical.. I think "translucent" is what you are referring to as "semi-transparency". (If I'm wrong, please correct.) Aventurine will also have little flecks/shimmers in it (at least mine does) at certain angles because of the feldspar that is mixed in with the chalcedony. I haven't cut it in a while, but if I recall correctly, I you need to be sure of the orientation to get the full effect. otherwise you just get a flaky surface and no little shimmers or specks from the included feldspar. |

Hi, yes that's what I meant, translucent. The image you provided is a good one to compare (well, for the translucent part) There are no flecks of anything in my piece, and it really hasn't the translucent look to it what so ever (nothing like in the picture anyway) Ah, I wish my eyes were better...grrrr @ old age! lol While sitting here looking at it, it looks bluish green (in darker lights, with these old eyes anyway) and it's got some pretty bluish places on it (blues and green, greens) This is what made me think it was turquoise when I first saw it. But, I know very little about turquoise (used to be my least favorite stone) The other thing about it, is it looks naturally wet (shiny), compared to other rough stone/rocks I've seen, for whatever that's worth Also, I wanted to ask, are there pretty knowledgeable people here with artifacts or ancient stone works? I'm just all over the place! lol...I knew this would happen. I'm so excited I found this place ;D I can't wait to post more, pick brains, learn and share (I'll be careful with the brain pickin part) |

Chrysocolla, possibly agatized from Arizona.

Going to have to agree with Redrummd.
Looks like it might be a piece of chrysocolla.

If it is chrysocolla, it is certainly silicified. However, the silicified chalcedony that i have seen has a smooth texture, not grainy like this piece, which is why I thought adventurine. Definitely not chalcedony, does not have the correct texture.

Hello again all! Sorry I was away the past few days. The images I googled on chrysocolla sure seem like a very good fit. The color is pretty spot on. I know nothing about chrysocolla, so I'm off now to read up! Thank you so much for this info. It may or may not be chrysocolla...but, at least I'm learning something new  I'll be back, you all be good! |
