Greetings all: Been while since I have posted and it feels good to be back on this site. I came across an interesting blue/green tightly banded rock that I figured was some sort of aventurine, but upon slicing, it does not transmit light, so it is primarily opaque, which surprised me. It definitely occurs in layers when looking at the rough piece so something originally laid down as a series of beds, and then silicified. It will not be scratched by a nail, and somewhat redundantly I even splashed with muriatic to no reaction, so is rather hard in the jasper/agate range, and it has just a bit of porosity. Thinking maybe a banded jasper or brightly colored rhyolite? Does some of the Ocean Jasper look anything like this? Most interested in a name and place of origin. Can't wait to make goodies out of it given its colors!
Thanks in advance for your thoughts on this.
