You have this backwards., Onyx marble is incredibly soft and has no relation to Onyx, the gemstone, which is black. Onyx comes in different colors, which can also vary in hardness. I think white is probably the hardest, while red is the softest, the deep green is in between.

It is very dense though, and I have never seen it get stained and have never need to seal it.

"marble" has different levels of hardness, they are not all the same and can vary significantly

Brady is right, Serpentine is much harder than most marbles

It is very easy to get trailing scratches when refinishing onyx, so cleaning the surface thoroughly between gits and making sure your diamonds are clean, scrub the channels with a brush so old, hardened slurry doesn't fall out and scratch.

Polishing can be one with a number of polishes. MB-22 works great, our Monster polish works well too, it's got a very fine grain to it. Use a white pad to polish.
Used monster few days ago, loved it. Honestly thought it'd be harsh, wasn't at all. Had a nice bite to it and worked pretty fast.

Looking to get into polishing and already took the class from IICRC. What equipment do you all use for the countertops. I have seen everything from ones that have water inlets to cheap multi speed grinders...whats your preference.

Rough day here, Grandfather went into ICU today, been withering away for the past 6 months since we lost my grandmother, I call it the Johnny & June cash illness...can't live without her. Rough day for sure, can't deal with another family death.

Already sick of winter, don't feel like doing shit, but keep pushing

That's good to hear, I'm glad you like it.

The Makita 9227C, which is now the 9237C is the most preferred it seems. You don't need a waterfeed machine to refinishing counters.
