Raw Terahertz Stone Appraisal

Terahertz Raw Stone

This item is identified as a large, raw piece of Terahertz stone, also known as Black Obsidian or Silicon. The stone has a somewhat irregular, organic shape, indicative of a natural break or unpolished state. Its most striking physical characteristic is its highly reflective, almost mirror-like surface, which displays a deep, dark, metallic-like sheen. This luster appears to be a result of its conchoidal fracture, creating a series of swirling, wave-like patterns and ridges across its dominant faces, which catch and reflect light intensely. The material itself is opaque, with a dense, solid appearance. While the exact dimensions are not provided numerically, a measuring tape, partially visible in the image, suggests it is several inches in height (possibly around 5-6 inches given the 'NORTH' marking at the top of the ruler) and seems to be of considerable weight. The visible ruler at the bottom, marked 'PIUMCREEK' and 'LEADERS', shows measurements up to 6 inches, indicating the width is also substantial. There are no obvious signs of significant damage like chips or cracks beyond what would be expected from a raw, fractured stone. One notable feature is a small, rectangular red mark on one of its flatter sides, likely an inventory or identification tag from the auction. The overall condition appears stable with no evident repair work. Given its raw state and the auction context, it is likely a relatively recent discovery or cut, intended for further processing or as a specimen. The quality is indicative of a well-formed mineral with excellent reflective properties, showcasing the unique beauty of Terahertz stone.
