This is Okenoite from Kenya. Gichuchu Okeno was a gem dealer and mine owner in his native Kenya. While exploring mining in Kenya, he discovered an interesting blue-green feldspar variety. After submitting to a few gem labs for identification, it became apparent that this was a new variety of feldspar, and is named after him: Okenoite. Sadly, Okeno passed away in March of 2016, so the future of this gemstone is uncertain.
