There is a single 0.75mm black crystal at the arrow plus a black zone, which is probably also Melonjosephite. The matrix is Triphylite, perhaps partially altered to Melonjosephite. The type locality description notes that Melonjosephite is an alteration of an Alluaudite group member. But, it is interesting to note that at the type locality, Angarf-South pegmatite, Alluaudite is not found (according to Mindat). Furthermore, Alluaudite is only noted at only two of the five pegmatites where Melonjosephite is found. So it may be worth examining your specimens of Melonjosephite to determine which Alluaudite group mineral is associated.

There are hundreds of tiny 1 to 3mm slender, colorless prismatic crystals of rare Milarite as singles across half of the Microcline matrix. I am not sure what the green mineral is. Perhaps it is Gormanite?
