🤍 HAND-SELECTED CORNISH QUARTZ FEATURE STONES 🤍

RTC Quarry is fortunate to have natural quartz veins running through parts of our Cornish quarry, creating some truly stunning feature stones.

Formed millions of years ago when mineral-rich fluids filled natural fractures within the rock, these unique stones showcase striking quartz formations, crystal pockets and beautiful natural patterns. Many of the pieces contain subtle rose-tinted quartz, which is often more noticeable in person than photographs can capture.

Each piece has been hand-selected for its character and individuality, making it the perfect statement feature for gardens, rockeries, landscaping projects and water features.

From Quarry Face to Chelsea Gold 🏅

We’re extremely proud to share that stone from our Trebarwith Quarry was featured in The Lady Garden Foundation ‘Silent No More’ garden, designed by Darren Hawkes for this year’s RHS Chelsea Flower Show, where it went on to win a Gold Medal.

It is an incredible privilege to see our stone used in such a beautiful and thoughtful way. A truly wonderful example, not only for the use of natural stone to create stunning elements within the garden, but also playing an important role in raising awareness of the five gynaecological cancers.

Congratulations to Darren Hawkes, The Lady Garden Foundation, and everyone involved in bringing the garden to life and thank you for showcasing our stone. 🪨🤘

Every wall has its purpose, but they are not all crafted in the same way. Every now and then, we come across something special. Something extraordinary…

A hidden gem shaped by seriously talented hands, turning raw materials into a masterpiece.

Created using our slate, this stunning piece of craftsmanship is a perfect example of the finest.

We’re very proud to see our stone showcased to this high standard.

If you’re a skilled craftsman looking for your next walling material, get in touch for prices.
