Dark Black Substrate?

So, I picked up a bag of black diamond a few months back, rinsed it, and dropped it in the tank. The first thing I thought was, this isn't as dark as I was hoping for. It was more like a dark grey color. Maybe it was just bad luck. I'm sure their QA isn't rejecting lots just because it isn't dark enough. So does anyone know of anything that's really dark? I was looking at the Flourite Black and the Black Moon sand, but it kinda hard to tell how dark they are by looking at pictures on the internet. Something that just sucks in all the light that hits it, not gloosy at all. A high CEC or lots of minerals would be great too, but for me it ranks lower on the list than looks for this project. Suggestions?

Tahitian Moon Sand is absolutely BLACK. IT is fine pieces, too, so no sheen.

Pebble Tek quartz is a blend, and while the BLACK pieces are really black, it is blended with lighter pieces. The pieces are a bit larger, so you might get some reflection of the faces, too.

Soil Master Select Charcoal (not available any more) was quite dark, but not true black. Flat black (or charcoal). No sheen.

Eco Complete (at least, the bag I had) is BLACK. Pieces are irregular enough that there is not much, if any reflection.

Sounds like Eco Complete Black or the Moon Sand then.

I think my eco complete lost its blackness over time. there are pieces of brown and red mixed in as well. its gorgeous when you first put it in and then it gets dirty and doesn't look as good, in my opinion

I have gone to a place far below up above and in between the middle.

How long did you have it in there before noticed it changed colors?
