Light Green glass cat's eye, fiber optic cabochon, synthetic oval stone, flat back. Measures 40x30mm. Made from Fiber-Optic glass, the way the light bends and plays in these synthetic stones makes them a wonderful alternative to genuine Cat's Eye stones. Each stone is a hand worked lapidary item, so 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 and will look good on many skin tones. Sold by the piece.
