Crystal habit: Flattened wedge-shaped crystals, Mohs scale hardness: 5 to 5.5 Crystal system: Monoclinic Free USPS / Free Economy Shipping The rare collector's stone Sphene is a brilliant transparent yellowish-green or green with a high luster and pronounced fire. Sphere'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. The name "Sphene" comes from the word meaning wedge shaped, as it normally occurs in wedge shaped crystals. Several gemological characteristics make it beautiful and desirable as a collector's stone or, with care, for jewelry use. Its dispersion (fire) is one of the highest of all gem materials, even higher than diamond. The body color, degree of inclusions, cutting orientation and cutting style may enhance or obscure this feature. If well polished, the luster can approach or equal that of diamond, but the gem is difficult to polish well. The high birefringence usually makes some doubling of facet images visible within the stone giving it a degree of internal fuzziness similar to that often seen in zircon or peridot.
