Barse Sterling Silver Blue Stone Earrings

Sterling silver earrings by Barse and set with blue faceted stones. I am unsure of the type of stone but looking through the backside it looks like they might be agate. Earrings measure from top of earrings down, 1 and 1/4th of an inch length and 5/8ths of an inch wide. Stamped Barse, Thailand, 925, and acid tests positive for sterling silver. C2
