The second one looks kind of like Marra Mamba Tiger Eye to me.

First one is Apache Gold - or other chalcopyrite in black schist from a different location.
Second one does look like it could be some kind of tiger eye matrix, based just on the band near the bottom of the rough piece.

Thanks! Do you know if there a specific method for polishing apache gold? I thought that might be what it was and read can get good polish on it. Assume would need to be done not in tumbler as it's super soft. The black practically melts when use any dremel bit on it.

I LOVE the way you cut that cab! Thanks! Still learning/playing around with dremel to make shapes and pendants. Though it's super time consuming and frustrating at times its relaxing in a way.

So I picked both of these up from keith harmons last rock sale in rusk tx and wondering what they are. The first one is really soft, tile saw cuts it like butter. It is really messy when cut and seems the black parts of rock are the culprit since water gets stained really dark greenish black color and sorta stains fingers/hands black. The goldish colored area has lots of shimmer wet or dry. Rough piece is wet and shaped piece is dry. The first ones look like Josephine's crown (I have seen other posts with different names, but similar material), which is Chalcolpyrite or Pyrite. The black is likely from the sulfides - my Josephine's Crown has a white quartz matrix and still turns the water black. You should also see a green/black on a streak plate. The lower stones look like a fairly new stone called green blanket, which has patterns similar to Indian Blanket and Noreena, but is fairly soft with a low luster polish. BP Next for id is definitely harder than first stone but softer than agate. Wild guess on hardness would be 5-6. Entire stone has almost a metallic/glittery look to it. Hoping this one can take a run in vibe to polish bc daughter requested a necklace pendant with some green in it for Christmas and this is one of few rocks I have with a nice green color to it. Both pics are wet. Thanks for looking and for any help can be in identifying these!

Can actually see a small amt of it on edge of the shaped pic.

Dry file your cracked areas with a nail file 180 grit is good. Only take about half the dead skin the first time around, keep it soft with something then file it again in a few days.

Hello again. Some of the Apache Gold from Jerome - I assume it was from a boundary layer in the deposit - can have harder light gray areas. Similar material has been found in other places, so it's almost inevitable that other matrix material would be found in some specimens.
For shaping and polishing softer materials I like Eastwind resin disks on a variable speed flat lap. Nova wheels that are well broken in work, too, but sometimes a slower speed is a big help. Smooth side of a soft leather is also good.
