How do we guarantee our quality standards

What transpires over almost a century is that our family business has always been a pioneer in the UK stone industry. By driving innovation in craftsmanship, we create, design and produce products that are optimised for longevity, sustainability and aesthetic beauty.

Gemini Quartz, the most durable worktop surface

Gemini Quartz has been independently tested by global quality standards company SGS and we are proud to have the industry’s highest rating performance quartz surface for heat, stain, impact, and scratch resistance.

In addition, our quartz has the highest flexural strength enabling the longest unsupported overhangs within the UK. Safe and Hygienic Gemini Quartz is NSF food hygiene and Greenguard Gold air safe certified.

The perfect fit

At Gemini Worktops we ensure your worktops fit perfectly in their new home with our vetted, safe and reliable installation teams who are local to your area.
