Didn't see this one in this ID section, so thought I'd add it. I think this stuff is a bit soft to take a good shine (haven't tried). One theory for ocean jasper is that it formed as an orbicular rhyolite that became completely silicified. The patterns would seem to match at least. -Don Orbicular rhyolite, photo with slab wet:

Ive got a bunch of orbicular rhyolite. I just love the patterns. I have a slab just like the one you posted.
Only bad part about it is that because its softer than jasper, it often has pits. Rainforest Jasper is a good example of a rhyolite that is called "jasper".
Thanks for sharing!
