Here is a cute pair of earrings set with distinctive boulder (we call it "ribbon" for obvious reasons) turquoise. Keep in mind the hangers are also Sterling silver—so they shouldn't bother people sensitive to other metals. Each earring weighs a quarter-ounce. Length, excluding the hanger, is 1 and 1/8th-inches; width is one inch. Hallmarked "AL." The third pic is of a "boulder" with the ribbon of turquoise contained within.
