Not sure what all these minerals are, going off of the 1st picture, I think the top right one is marcasite and the one under it I think is anatase, then would anyone know what the others would be? Im guessing the 2 on the left and 2 in the middle bottom are pyrite and some of them with galena/quartz/matrix but I'm not 100% sure if pyrite is that metallic. The only other guess I would have it maybe chalcopyrite. Then I have no clue what the top middle one is, but it does have some red translucent crystals. Thanks And I forgot how to get the correct image link from google drive, so here are just links to the viewer drive.google.com/open?id=0B0gO2dw2ik27dkZCSVBwcW1WUXM&authuser=0drive.google.com/open?id=0B0gO2dw2ik27djFQR3FRVHpwbzA&authuser=0Edit, galena is out on a streak test, and with a brown streak im guessing hematite on pyrite. And going through mindat the top middle mineral keeps going to marcasite, but I cant find a picture that looks the same.

Bottom left of the 3rd pic is almost definately Galena. Top right too.
Top left of the 4th pic is Pyrite.

First, garnet can take a number of shapes. Even massive with no defined shape.
On zooming your pics to the max, I can see cubic shapes in some. Have you tried scratching any of the pink material with a knife or needle ? If it scratches fairly easily. flourite is a possibility.

If not garnet as jakesrocks suggested, I wondered if it may be rubellite tourmaline? Do any of the crystals radiate? Are you able to give a locality for your specimens, jf23?

That is the only intact clear crystal on it that I can pick out, and the only pattern I can see is they are in/on the pink crystals. And possibly some of the minerals came from around the Missouri area maybe like the marcasite, but can't be 100% sure.
