Barytolamprophyllite from Tausonite Gora, Murun massif. This mineral is pretty rare in Murun, except at Tausonite Gora

Barytolamprophyllite from Rasvumchorr, Khibiny
Barytolamprophyllite from Yukspor, Khibiny. Often Barytolamprophyllite is paler and more golden in color, but this
material looks a lot like normal Lamprophyllite!
