Naturally Biterminated Clear Quartz Crystal with Specularite phantom. Specularite is a variety of Hematite known for its metallic luster, in this case, naturally forming into a phantom mountain.  Not only does this piece shimmer with an internal mountain, but it has a beautiful flashing rainbow at the base, further enhancing the magical quality of the stone.
