Not every kitchen wants a mirror shine on the counter. Avant Chamonix takes the opposite route with a matt grey engineered quartz, 20 mm thick and made in China, that keeps reflections soft under pendant lights.
Sealing never enters the picture, since quartz is non-porous; just keep a trivet handy for hot pans. Our own installers fit the worktop, so the people who measured your kitchen are the same team that sets the stone in place.
Frequently asked questions
How much does Avant Chamonix cost?

Kitchen worktops and islands in a modern or industrial scheme, bathroom vanities and window sills. The matt finish is a good fit wherever you want low reflection.
How do I maintain a matt quartz worktop?
Engineered quartz is non-porous and never needs sealing. Clean it with a mild detergent and use a trivet for hot pans.
When can Avant Chamonix be installed?
Installation 10 working days from drawing approval. Our team laser-measures within a week of the order, and a lifetime warranty on the stone surface applies when Stoneks measures, delivers and installs.
