This stuff cabbed up super nice, I thought it was going to be like rhodonite but it's not at all similar. Any thoughts?

No, and I expected it to Tela. It's much harder like an agate. See the clear areas?

The black looks like manganese and the pink looks like orthoclase. Could actually be pink Tiffany stone, which is much more rare than the purple.

the cab on the dop stick is Tiffany and leans into the brown pink colors, the slab on the left isn't reminding me of Tiffany now that I compare them. It's denser than any of the 3 other types of Tiffany I've cabbed so far. That was leading me into another question maybe for another area. Why so many different types of TIffany? The first I got is more clear and has lots of fractures and crustal drusy areas, the second is way more opal-like and opaque. The third is pictured here.

There are various types of Tiffany stone because it is not a specific mineral. Tiffany stone is a name given to a mix of different minerals, up to 16 different minerals. These include quartz, chalcedony, fluorite, manganese, dolomite, calcite, opal, bertrandite, etc. So it can vary in color, pattern, hardness, density, stability and composition.
Look at the pink and black Tiffany stone at this site:
And some other examples:

Could be an odd CA rhodonite, too. I'm thinking it's not tiffany. I've seen rhodonite in agate.

This is the first slab of Tiffany I ever saw. If it hadn't been written on I wouldn't have thought it could be Tiffany. This is so much clearer and more brittle than the waxy opaque material I got the second time around.

Could be an odd CA rhodonite, too. I'm thinking it's not tiffany. I've seen rhodonite in agate. I'm in agreement. I am almost certain it is rhodanite. It's a local material here and I see it for sale frequently at shows and sales and the pink white black mix in areas of your slab are very common - I have a piece around here that looks just like it. The presence of clear areas indicating agate is less common but not unprecedented.

It only matters because I intend to sell it, so you think I can call it rhodonite with reasonable accuracy? If not it goes into "mystery/freebie" pile. Still is pretty no matter how it's named

More of an educated guess? Around here when we see pink interspersed with stringy black and areas of white it's always labeled as Rhodonite.

James you're much more than a rock enthusiast! What is your profession? Posting another pic in next reply Been in medicine for 40 years. Rocks are more of a hobby that I was brought up with since that is pretty much all there was to do growing up Las Vegas. I spend a lot of time doing research though on various subjects including rocks.
Problem with your stone is not knowing where it is from. Again Tiffany can be pink and often has black manganese veins. But so can some other rocks. And there are different stones that can be pink such as this orthoclase:
Knowing the origin would help. Otherwise would probably take an analysis to determine what it is composed of to give it a name. Without that it is only narrowing it down by guessing based on what can be seen in the pic.
