Super-lustrous crystals of deep amber color, to over one centimeter. The luster is near-metallic in quality and its one of the BRIGHTEST specimens of the material I have ever seen, in terms of sheer "sparkle." The amber crystals have formed over a layer of very dark crystals, making them really stand out and also giving the specimen fine 3-dimensionality. From the finds that re-defined how beautiful orpiment can be and also set a new standard for orpiment from the US. 6.3 x 4.5 x 4 cm
