Without seeing the back of the piece i cannot be positive. But i suspect it is glass. No stone i have ever seen has a pattern like that one.Hope this helps.

The back is closed up so I guess I'll never know for sure.
I thought it might be a jasper or agate but I'll take you word for it.
Thanks for trying.

Glass is very cold,compared to stone.cant you compare it with a piece of stone?
Jade is poor conductor of heat and cold but not cold enough compared to glass/

It reminded me of glass marbles i had when i was a boy at school. If it was agate the lines would not join to a point like that. At least none that i have ever seen. I used to mine agate. And most jaspers i have seen are usually a plain color. or they dont have lines like this one does.

I may have to redo the photo - it has less lines or they aren't as defined as in the photo. Too much flash I guess. I'll try to post another photo tomorrow.
It is cool at first but warms up fast. Does that mean anything?

I still think it is glass. unfortuanately the best way to find out is to have the piece taken out of the setting. It looks like it is glued in. The back will tell the story. there will be some sort of mold mark or mold pattern on it.

Thanks Paloma - nice sites - I had the first one already but the other are great as well.
Here another piece I have if anyone can help ID this one - I have the photo but I can't put my hand on the ring at the moment. I think the back is open and it's definitely a stone if I remember correctly.
Agate - I'm sure you must be correct - I guess it really doesn't matter that much anyway as agate doesn't really add much to the value.

Could it be shell (the first ring)? The 2nd ring looks like variegated jasper to me?

ladyjewels2000. I have been in touch with an glass maker of cabochons. They said it is what they call an art glass cabochon.

Pixie - I think it's too smooth to be shell. I believe Agate18 is correct it's glass.
The ring maybe Zoisite - I'm going to check the site Paloma gave us and see if that works.

I would use "slag" as a keyword on the glass piece.

The second photo is a real stone. I was double checking with a friend just to make sure. It is Morenic chrysocolla Malachite.

Thought malachite and chrysocolla were two different types of stones. I do know that most chrysocolla is generally too soft to be cabbed but there are some varieties that are hard enought to be worked Isn't it called an eliat stone in Israel and popular in the jewelry that comes out of that country?

The one thing they all have in common is that they are all copper. Just different types. And yes they can all be polished. You just have to be careful how you go about it. As they are all soft. Inc malachite.
I have cabbed chrysocolla on its own and it was of a high grade but i still had to be careful. when you get them all together they seem to be a little harder.
The quality of your polish will depend on the quality of the material. And yes there is definitely some you wont polish. eliat stone is very soft and you do have to be careful when polishing it.
Most of these really are too soft for jewllry, at least i personally think so. If you brush something like a timber wall you will scratch it or even gouge .
