Mystery rough identified: my friend @salmangems85 encountered a small parcel of unknown green crystal fragments in the gem markets of Peshawar, Pakistan, and kindly sent it to me for analysis. The rough exhibited interesting pleochroism that suggested it might be something interesting, possibly Kornerupine. These were found at one of the Andradite Garnet mines in Balochistan, Pakistan, and mixed in with the mystery minerals were some Garnets, including a few that were green and gemmy enough to qualify as Demantoid Garnet, as well as Diopside and some non magnetic yet metallic diamond shaped crystals. Raman spectroscopy was performed on the unknown samples and they were determined to be Enstatite, a mineral that is rather uncommon as transparent gem material. I've seen brown crystals from Tanzania, and brownish olive ones from Myanmar before, but I've never seen specimens this green before, and had never heard of gem Enstatite from Pakistan before. I was all excited to write up a Gem News article for GIA's Gems & Gemology Journal, only to discover that a small parcel of this material had first surfaced in 2007, and had been characterized and already published on in 2009. The article explained that the green color derives from both Chromium and especially from Iron. If you received a box of mineral specimens recently from me, there was likely a sample of this rather uncommon material in your package, marked as unknown.
