Kelly,

 

Treat the onyx the same way you would a marble, hone  it polish it . you may need to hone up to an 800 grit then I would 5 X polish.

 

I would start cutting the lippage with a 40 grit metal or 100 metal then move to resin diamonds once the floor is flat.  40 , 100 metal then 50 , 120 220 400 800 resin diamond 5 X polish

Hello Gang -- I have an onyx floor job and there is some severe issues. Wondering if anyone knew how difficult it is to grind down bad lippage on this stuff. Is it more like marble or granite or somewhere between? Thanks in advance for any insight. steve k

To everyone,
We are doing a restoration job for an entire apartment in Manhattan and they have a onyx vanity and sink in one of the bathroom which have become dull and needs some facelift .
They were originally polished, but across time and use they have lost their
sheen. I have no experience with onyx. Does it polish like marble? Is it
hard like granite? I haven't the slightest idea. Any experience out
there polishing this stone?
