Pink glass cat's eye beads, fiber optic glass, faceted round beads. Measure 4mm. These synthetic cat's eye beads are fully round with cut and polished facets. Made from fiber-optic glass, the way the light bends and plays in these glass beads makes these facets sparkle with color. Since each bead is a lapidary item, natural variation in color, shape and sizing may occur. No two are exactly the same, but that is also the charm of these stones. The color is just beautiful. Packages of ten (10) beads.
