Off-white quartz with dense fine multi-tonal speckling — a calm, practical surface with subtle natural texture.
Sempre Sierra presents a quiet, dependable surface with genuine textural interest. Its off-white base is infused with a very fine, dense granular texture of abundant irregularly shaped particulates in shades of very light grey to subtle warm brown-grey, distributed evenly without any veining or directional movement. Scattered sparsely among these are tiny pin-prick dark grey to black speckles that add subtle contrast. The matte, honed finish avoids reflections, keeping Sierra feeling solid and grounded. The multi-tonal speckling gives it more character than a solid colour while remaining firmly in the understated category. Sierra is designed for kitchens that want their worktop to be practically invisible — always clean-looking, always appropriate, never distracting. Manufactured by AKG Surfaces in the Sempre range with a 25-year warranty. Available in jumbo 3200 × 1600mm slabs with 20mm or 30mm thicknesses. Supplied and installed by In2Stone across Hampshire.

"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
