What I prefer to polishing with: Cerium oxide with a Spectra Ultralap.

Jeff’s Comments: Cuts and polishes like any other Quartz, usually no problems. I like to use a 1200 Nu Bond lap for pre-polish, it makes the polishing stage faster and easier. Orientating on the “c” is slightly better.

Design Notes: About any Quartz design will work well. As the rough gets more saturated, I prefer checker boards and bar cuts. I prefer to cut large clear Quartz, they are actually pretty impressive, especially for material that costs almost nothing.

Design Links: 4-Way Stop – This is great for saturated rough if you have a piece that will work in the shape.
