caption_attribution_description: English: Apatite, Aegirine Locality: Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia (Locality at mindat.org) A totally unique piece to my experience, that is really quite mesmerizing! The aegerines or dark tourmalines as they had been previously (mid)identified add to the weird effect of the piece. It seems to be complete all around, nearly a floater, and its just plain weird-lookin'. But for an apatite or Russia collector, weird is good...It is so weird, I had never seen one and had no idea that i was passing along a label error as i bought it as Heliodor with Elbaite 2.7 x 2.3 x 1.7 cm Deutsch: Apatit, Aegirin Fundort: Kola, Murmanskaja Oblast', Northern Region, Russland (Fundort bei mindat.org)
