Sorry I can't help but would love to hear too! Considering honed caesarstone for my kitchen counter tops.

Someone will have a definitive answer, but I don't think you can hone the various quartz products. I wanted runnels for a drain board on my quartz counter. The fabricator said it would void the warranty. Instead, we designed a work around. He said any changes to the surface would void the warranty. I suggest checking with a fabricator to see if honing is permitted.

Caesarstone actually makes 2 or 3 products in a honed finish now. White, light grey and lighter grey. It comes from Caesarstone honed.

I have spoken to a couple of Caesarstone reps about honing a product that comes polished. They have told me it's expensive, you're adding the cost of honing onto the entire purchase and fabrication cost, which isn't cheap to start with. But they've never said anything about the warranty.
