deb gave me a strand of ancient excavation beads which included these incredible fossilized sea urchins. nomadic people in mali made them into beads 2000 years ago. the carnelian beads are of the same age and region.
old pressed amber beads tina and i collected in the 70s when we were teenagers. i bought the victorian coral just after the import ban, before the price went up- i could never afford it now.
