Ther large somewhat flat bright yellow beads are treated cow horn from East Africa, made to be frankly fakes—though in one instance I know of someone buying them as "African amber." The horn is apparently boiled in oil to make it more translucent, and then dyed.

The spheroid beads to the top left and lower right look like the "late phenolic" beads that made their first appearance in the late 1980s. Although they were also sold as "old amber" they have a distinctive (and new) look, even though they are derived from preformed canes (like the older phenolic beads). Since I haven't tested any of these, I am not positive they are phenolic.

The small shiny bead looks like glass.
