Guess by Marciano Silver & Blue Hoop Earrings

Really cool turquoise and silver (not sterling...i think these are pewter, but I am not sure of the contents) lever back hoop earrings. These were purchased at a Guess store in 2005. Not quite vintage, but getting there. In perfect condition. I just don't really wear earring ever. They are about 3" long. Hoop part is about 1.5" wide.
