Upcycled Screw Back Shell Earrings

From the pile of leftover pieces from converting/remaking my vintage jewelry stash. Old fashioned screw back tops, with rhinestone, probably from the 60's. Hanging from them we have some shell pieces left from a necklace that was re imagined. The shell pieces are approximately 1" by 7/8". Total length 1 5/8" . As with all natural jewelry, the pieces are not an exact match to each other. Fun colorful earrings!
