What makes Gemini Quartz the best?

Gemini Quartz was first launched in the UK in 2003, and our mission has remained the same since that day; we want to offer both quality and affordability.

We don’t believe our customers should ever have to compromise. We have used our four generations of stonemasonry know-how to ensure our product is the very best there is on the market.

Here, we list the key reasons we know Gemini Quartz delivers the ultimate value and performance our customers can expect.

At Gemini Worktops, we don’t believe in empty words and claims. We rely on empirical data to verify what we know to be true.

As a result, we had Gemini Quartz tested by the global leading testing company, SGS. We compared our own Gemini Quartz against the international brand, Silestone. The results speak for themselves.
