Horizon Stone is a secondary brand run by Classic Quartz. Historically, Horizonstone tended to be used for commercial, large scale, multi-unit kitchen jobs – blocks of flats and other new developments. It was regarded as cheaper and not as good as other Classic Quartz materials.

We feel that this has changed. Some really very striking materials have come through from Horizon Stone – probably at the top of the list their amazing Calacatta Bronzite.

The Horizonstone range is not huge but it is quite fluid and we can’t track all of the changes on this website. So here are some of their offerings in quartz worktops, as of March 2025.

Horizonstone Monsanto

Whether or not it is a good idea to name quartz worktops after a brand of genetically engineered soya beans, we have actually fitted many kitchen countertops in this stone. People really like it.
