My sister in MA. has taken an interest in going to rock shows, and I have become the beneficiary of some of that. I think honestly I'm helping her out, giving her slabs to focus on- gives her a purpose at the show.
And she knows, she'll eventually get some jewelry out of them.
So she sent me these nice slabs from her show in Kent, CT.
But I'm stumped on some of the ID's, mainly of these three.
First one was labeled "Canadian Jade". The color in the photo is pretty close, it's a lite sea green color. I have seen jade from Canada and I think it's darker, and there's no "waxy" look to this slab.
The next two, my sister was very proud to tell me she had the IDs- they are both a Jasper So, any specific type of jasper ?
I didn't pull out my hokey hardness test, as I think I throw off the ID's since the test is very inconclusive.
But if you think it will help, let me know & I'll make some chicken scratches
Thanks for any help on the ID's,
Patty

The first one (green) looks exactly like a chunk of aventurine that I have. Right down to the white and brown stripes through it. Will try to post a picture later. From what I have read, I suspect it is from India and likely dyed green. But it is a neat material to work with regardless.

WOW, Chris the dyed part is something I'm NOT going to tell my sister about.
Probably would have fooled me at the rock show too. In your experience, does the dye offer any issue with grinding & polishing ? I'm guessing at that rate the stone must have started out white or very light color?
Thanks for your input- I'd love to see a photo of yours.

Wow! Your jasper looks like good ocean wave jasper- cousin to ocean jasper.

In my excitement I forgot to mention the nice polka dot agate, too. And I agree with Indian Aventurine.

Thanks for the ID's Tela, & the confirmation. I never would have guessed Ocean Wave Jasper. I mean, oceans are blue, aren't they ? ! Glad for the Polka Dot agate ID, Tom keeps calling it "white blob agate" - so thanks for saving me from that !
Most excellent- I have real names Thank you,
Patty

Here is a photo of a aventurine rock that I have been taking slabs from. Also a couple of polished versions. You can give an opinion on how you like the color combination on the bracelet. My sister-in-law said you should make bracelets all one color but I like the black and green combination. Here is a description of aventurine that I found: Aventurine is a form of quartzite, characterized by its translucency and the presence of platy mineral inclusions that give it a shimmering or glistening effect termed aventurescence. The majority of green and blue-green aventurine originates in India where it is employed by prolific artisans. The most common inclusion in aventurine is fuchsite, a green chromium-rich mica. Just a few percent fuchsite by volume can impart a distinct green color to aventurine. Because it is quartzite, polishing isn't always great. I am thinking this is dyed (just a guess) because the rock shop where I bought it had tons of it and it wasn't very expensive. Somewhere I read that most or a lot of it from India is dyed. Regardless, I really like working with the material. Chris

I look forward to cutting some cabs with mine.
Your star ornament is wonderful, and I really like the 2 tone bracelet.
If it was all green stones, it wouldn't be as interesting, IMO.
Thanks for posting the photos.
