'Grey Diamond' — Italian-named granite with a sleek, minimalist surface of uniform cool grey and virtually no visible patterning, accented only by tiny light-catching mineral flecks.
Grigio Diamante — 'Grey Diamond' in Italian — delivers diamond-hard durability beneath a surface of exceptional minimalist purity. This uniform, medium-cool grey granite features an extraordinarily fine, smooth texture with virtually no visible patterning, creating a sleek, modern surface that's as close to architectural uniformity as natural stone can achieve. Scattered tiny light-catching mineral flecks add a subtle diamond-like sparkle. The name captures both the stone's colour and its defining quality: diamond-like consistency combined with diamond-like durability. Composed of the classic granite mineral trio — mica, quartz, and feldspar — Grigio Diamante delivers all the performance characteristics associated with quality granite while maintaining one of the most consistent surface appearances available in natural stone. In2stone recommends Grigio Diamante for customers who love the minimalist aesthetic of engineered surfaces but want the authenticity, heat resistance, and UV stability that only natural stone can provide. It's the perfect choice for sleek, contemporary kitchens where uniformity is valued. Pair it with handleless cabinets in white, pale grey, or charcoal for a gallery-like kitchen that puts simplicity on a pedestal.

"We decided to get bespoke granite work tops for our new kitchen and have to say that we are over the moon with them. From the outset, Ian was very professional when selecting the stone, he listened to what we wanted, went through all of the possibilities that we could have for our worktops and went through the process in detail once we had made a decision. The templateing and fitting was carried out by an incredibly professional and helpful team run by Kev, who knew exactly what they were doing and just got on and made my kitchen look amazing. I would highly recommend In2stone for a helpful, knowledgeable and professional service from start to finish."— Nicky HavardGoogle Review
