The rare collector's stone Sphene is a brilliant transparent yellowish-green or green with a high luster and pronounced fire. Sphene's magnificent fire, unique color shades, strong pleochroism, adamantine (diamond-like) luster and double refraction make it ideal for earrings and pendants that catch the light and show its sparkling qualities. Occasionally pink, black or brown, most Sphene is predominantly green or yellowish-green, with colorful flashes of a rainbow of hues.
