Found these two strands while clearing off my work station. Obviously I have a favorite color when it comes to beads!

The smaller, rounder beads are a costume-jewelry necklace, and they are plastic. They look like a lot of work for plastic!

The larger beads are glass. Looks like a partial necklace, or perhaps restrung.

Both "bases" look similar, sort of a concrete texture, with the blues drizzled on.

Any info would be deeply appreciated.
