These are Swarovski Montana blue rivoli crystals, set into pewter (no lead) frames. The teardrops are Swarovski Indicolite crystals, a shade of blue-green which is lighter than Montana blue. These are great, uncomplicated earrings, not overdone, but with some substance, sparkle, and fashionable color. They are 3/4" wide, and 1 1/4" long from the bottom of the sterling silver leverbacks.
