Re: Calling all faceters

Hi Ward,

I am not familiar with "Fantastic Film". However, there are polishing disks available which consist of a thin layer of mylar-type plastic embedded with polishing compounds such as cerium, aluminum, chrome and tin oxides as well as diamond bort in 1200 through 100,000 grit.

These are the ultralaps and spectralaps. They have no structual integrity and must be used on top of a master lap or directly on top of your prepolish lap. I particularly like the spectralaps for polishing quartz and other materials that polish well with cerium oxide.

The diamond impregnated ultralaps seem rather pricey to me ($22.00 each for an 8" lap) considering their relatively short lifespan. If you regularly polish materials requiring diamond I think you will be better off in the long run with a rechargeable metal lap, but you pays your money and makes your choice. There are some situations where a diamond ultralap can provide a magic bullet without breaking the bank when having difficulties polishing a particular stone that normally responds well to oxide polishes.

More information on these laps is at:

Keep on rock'n and may all your scratches be small ones... :)
