Hackmanite, Cryolite, and Feldspar; Kola Peninsula, Russia

Some think this piece looks like a cross between Nemo and Dory, regardless, it's an interesting and allegedly relatively rare. It's hackmanite, cryolite, and feldspar from Alluaiv Mountain, in the Lovozero Massif on the Kola Peninsula in Russia. The hackmanite is very bright in longwave, mildly bright in shortwave, with a slight tenebrescence (not shown). The cryolite is baby blue in shortwave, while the feldspar is a dull, deep red in shortwave. The piece is about 3 inches by 2 inches, and shown here in shortwave, longwave, midwave and natural lights.
