I'm polishing a cz on batt with 100,000 diamond. Getting very fine scratches visible with naked eye. Searching for best recipe to polish czs. Thanx.
You can find the results of a polishing CZ survey Gem Society conducted some years ago here. There are numerous recommendations and notes from members. Hope this helps.
100k Diamond should not provide scratches in a CZ. The can be polished with 8K, leaving no scratches. I had a similar problem- it turned out that my polishing equipment was contaminated with chips from the grinding process. I was using a soft rag to wipe the stone, and forgot to change it between cutting and polishing. Wash and wipe the equipment before polishing
I polish CZ with lead-tin lap and Diamond powder, an oil lubricant with low speed and it works well. Always befor polishing clean your machine.It could be contminated.
contaminated is the right word
I switched to my dark side lap. Very light wd40, slow speed, and light pressure. Worked very well, slow though. Then i got a diamatrix lap. Light wd40, slow speed ( 1.5 on my facetron ) and light pressure. Very fast polish on synthetic conundrum.
