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.
Design Notes: About any Quartz design will work well. As the rough gets more saturated, I prefer checker boards and bar cuts.
Design Links: 4-Way Stop - This is great for saturated rough if you have a piece that will work in the shape.
