Hi, Elizabeth! I can describe each of those for you. I hope this helps!:)

Galvanized: The shiny finish on these beads gives them the appearance of metal and referred to as metallic beads. They are not in the metallic bead family. Until a few years ago (see PF beads) they were highly unstable and were avoided by some users. New technology has created a much more stable bead.

Silver-Lined: A sterling silver lining has been applied to the inside of a transparent or translucent bead creating a mirror like surface that transmits light from the center of the bead. These beads also come with a "frosted" finish.

Thanks!
