pornite

a particularly attractive geologic specimen that upon expert examination provides a uniquely or strikingly well articulated lithographic expression, mineralization, or other geochemical condition

As the geologist scanned the unusual outcrop his eyes fell on an exceptionally gorgeous specimen. With chisel and hammer in hand, he moved to carefully separate the country rock from the sample he knew others in the office would admire with great enthusiasm. This went far beyond basic bornite; this qualified as genuine pornite!
