A rarely seen, sharp, euhedral, orange-pink, hexagonal single crystal of Sapphire from the Morogoro area in Tanzania. This is one of the few crystals that I have seen from this area in a while, mostly because nearly 99% of the crystals from Morogoro end up either being faceted into stones, or are sent to Asia to be carved. This crystal has good luster for the locality, and the color is not terribly common from this area either.
