Re: Re: I am completely enthralled by this stone

If you look at the 'flash' pic, you can see planing near the lower finger amplified by the flash. Opal has the same fracture qualities of other silicons with the concentric circular lines. None of that is present. Plus, that really looks like black tourmaline, which would be quartz or feldspar.

Either way, a very unique specimen. If there is more, wow.
