Specularite is a variety of Hematite known for its metallic luster, in this case, naturally forming into a phantom mountain inside of crystal quartz.  This piece not only has shimmer from the internal specularite, but it also showcases a small glittering rainbow at the base of the internal phantom. 
 
Metaphysically, Specularite is associated with anchoring, protective, and grounding energies.
