Black Diamond
The Stone
See the natural beauty of Black Diamond up close — the surface texture, colour depth, and veining that make this porcelain unique.
A deep, atmospheric dark stone porcelain with warm brown undertones and subtle mineral veining.
Black Diamond conjures a moody, atmospheric depth through its rich charcoal-grey surface punctuated by cloudy lighter patches and fine mineral veining. The base is a deep, complex dark charcoal with warm brown undertones that prevent it from reading as merely grey or black. Patches of lighter grey-brown create soft, cloud-like transitions across the surface, lending an almost weathered quality. Very fine white hairline veins and golden-brown mineral traces thread through the stone, catching light and adding geological authenticity. This is a surface with genuine depth — each section reveals different tonal subtleties depending on the light. A sophisticated choice for kitchen islands and feature walls where the warm, layered darkness creates an enveloping, luxurious atmosphere.

"Excellent Service and Beautiful Results - Highly Recommended! I recently had In2stone install new quartz worktops in my kitchen, and I couldn't be happier with the results. From start to finish, the experience was completely stress-free. The team was not only competitively priced but also incredibly friendly and professional throughout the entire process. They handled everything seamlessly - removing the existing sink, hob, and old laminate worktops before fitting the new quartz surfaces. The finished worktops are absolutely beautiful and have transformed my kitchen into a modern, minimalist space that I love spending time in. The quality of workmanship is outstanding, and the attention to detail really shows. I'm a very satisfied customer and would highly recommend In2stone to anyone considering new worktops. Well done to the entire team - you've exceeded my expectations!"— Ashley ChapmanGoogle Review
