MsAli I am not sure what that is, but I do like the colors.

I am not sure what that is, but I do like the colors. To me, it looks like some of the more translucent Colorado amazonite. It definitely has blue crystal forms showing that resemble amazonite feldspar, and the "webbing" pattern also seems right. That said, some of the Mt. Antero aquamarine can also look similar in a photo - going to have to do a Mohs hardness test if you have any scraps left over. You certainly made a trio of attractive cabs from it!

</div> Amazonite is colored by lead so a lead or density test could probably help.
To test for lead or copper I would probably try a flame test.
