Here are some photos of some Red Ribbon Obsidian that I have been staring at, cutting and polishing.
This is a rough piece that shows the red bands that I work with. They usually are somewhat wavy so it is hard to get a single band to go across the full surface of the cab but that doesn't keep me from trying. In these bands you can see that the red doesn't continue all across the band and the rest of the band sometimes has the same pattern but just not in red.

Here is a photo of the side of the piece where you can see indications of where the various bands are though most of the time most of the bands do not contain the desirable red colors.

The rest of the photos are of a single piece that I cut the slab from that I recently posted. This is the same end that the slab came from.

This is the smaller opposite side of the piece.

Same end turned sideways.

A view of the side of the piece showing faint lines where the bands are. This piece had the red bands more consistently throughout the piece than usual.

A small slab cut from the smaller end of the piece.

The other side of the small slab.

The original slab from the larger end of the piece that I had previously posted.

I hope everyone found this to be interesting and enlightening.
