Rainbow or ???? Black Obsidian
Ahnlaashock:
I went to get a good sample of rainbow out, but all I have is the purple sheen material left.
Outbackbob48:
Stocker, looks like banded obsidian to me :o I'll see if I can find a blade someone sent me of Rainbow, I'll try and get some pics tomorrow. Later Bob
StevenT:
Yea, from the pic it looks to be obsidian. I have my doubts it originated in NM. Doesn't really matter though, it is a nice looking chunk of material.
aaron:
rainbow is hard to photograph. I'd say the o.p. may or may not have it,,,the colors show when light bounces off it, not shining through. the colors only show at a certain angle of view- you have to turn it in your hand until the colors pop out (or not). Some is much more colorful than others. google it for some striking examples. viewed under different light or angles these would all look black
Stoker:
aaron - Thanks for your example and explaination... I can see some voilet colour but not a lot.. It is hard to photograph.. I took 15 pics and showed the best 3...
Thanks Leroy
