We've seen this red-enhanced fossil coral over here in China, recently. Thanks for explaining it in detail. We did not happen to take pictures. I'll try to find some in the next few days and see what I can show.

I agree that both the "white" natural form (beige, really) and the new enhanced are very pretty and make great beads.

I also agree that this material will probably show up with tall tales of ancient Tibetan origins. Maybe we can nip that in the bud, or should I say, polyp?
