Schorl or black rutile?

From the cemetery --

The "V" twinning that can be seen on the top edge of the crystal makes me think rutile.

Extraordinary picture of the "V-twinning", Scott!
I have never seen that before. Very interesting.
I have to agree that it looks most like rutile, but is there something more going on there? Our missing Brookite? Just wondering.
Either or, a fantastic picture!

Here's one from the Cemetery that I "borrowed" from Josh.
The large black mass on this piece is what we have typically been calling schorl, and it may be. I cannot see any definite characteristics to say for sure. But a closer look at the small area of black at the top of the piece shows the reticulation of rutile underneath. Which poses the question: are these two areas of black different minerals?
The first picture is of the whole piece. Second is a close-up of the large black area. (Please excuse the hairs.) Last three pictures are of the smaller area.

And one more piece from the Cem, also borrowed from Josh.
I am "guessing" this is also black rutile. First two pics are one side of crystal, last two pics are the other side.

Oh yeah, that first one is weird! Huh
Thanks for all the great pics. I see you have been doing some searching!
I have been noticing that alot of the crystals look like "layers" welded together. Like in the 3rd to last pic above, it looks like each layer has it's own termination. The 5th from last pic above is a fantastic close-up of another example of layered crystal?
And, again, that first one is something else? Wink

My guess is that the black blocky crystals are schorl, and the long, reddish acicular crystals are rutile.  I've seen blocky schorl from Hiddenite that looked very similar.
