If it is from Kovdor Iron mine - it is rather labuntsovite-Mg, or lemmleinite-Ba, or both them.

I was told that EDS was done on it and that Parakuzmenkoite was the best match? Unfortunately I don't have a copy of the results and they are not available. Is it possible to distinguish the labuntsovite species by EDS? From what I can see from the published formulas they should be but then maybe in reality they are not compositionally that well defined? It would seem that Parakuzmenkoite is distinctive in that it has Fe and no Na whereas lemmleinite-Ba does?

Here is the qualitative EDS pattern for the sample. The thin vertical white lines mark where Ba should be, any thoughts on what it is based on this? Except for the color, Lemmleinite-K would seem to be a good fit.
