Ulas? Oceanic teaser

[Tim Simmons]

Okay I think I have solved the origin. Looking over this again I saw some white bits stuck deep inside one of the root cracks. Frist I though bits of foam packaging then insect remains then rice but with magnification they turn out to be one circular pearl shell disc bead and a broken sort of barrel shape bead. I think most unlikely to be anything else than Fijian Ulas.
