A beautifully polished Cobalt Blue Fiber Eye cabochon set in a gold or silver colored necklace with a beaded edge. Fiber eye is made from fiber-optic glass, and It polishes flawlessly. Iridescent streaks shimmer through the stone when it is rotated in the light.
Although fiber eye is man-made, it comes in rock form. Gary cuts it into slabs, then grinds and polishes it, one cabochon at a time, just as he does with any other stone.
