This is beautiful male troca shell hand cut into graduated rounds that drape like elegant pearls. Troca shells are conical shaped shells of sea snails which boasts a premium, very high grade, mother of pearl. The female has a pearly white shell, while the male shells may have colored striping. Here, you'll find pearlescent swirls that come together in an elegant bead accented with thin green, and occasional red, striping. Because they are hand cut, there is some slight variation in shape. But, they are very smooth with a high gloss polish. The graduated beads are perfect for a ready made necklace, or use different sized beads for different designs. Great to add a natural element, with a touch of elegance, to your designs. Come on, let's make something beautiful!
