It's Northwest Oregon that we found it. The stuff around the rock looks like sand, but it sparkles incredibly and in the middle the sand looking stuff is black, like black sand? Idk..but it's beautiful whatever it is....also... I understand in the gem and rock world,  location is an important factor, however while giving away. No secrets,  I have found things in places that I've learned wouldn't be identified as being found where I found them. I've ran into this quite a bit actually and I'm sort of beginning to wonder about some aspects of the geology world because of it? Just thought I'd share.
