Not sure which stone is right for your project? Order up to 2 free samples — just £5 flat delivery. Each sample is a genuine 100×100×20mm swatch cut from the same container-direct stock as our full slabs, so you can check the true colour and texture before you buy.

  1. Brazilian Black Natural Riven Slate
  2. Brazilian Black Honed Slate
  3. Brazilian Black Brushed Slate
  4. Black Riven Limestone
  5. Grey Riven Limestone

Highlights & Key Features

  • Direct-from-Quarry Stock: Samples are cut from the same container-direct slate and limestone we sell as full slabs — not a separate printed sample card.
  • True Colour & Texture: A genuine 100×100×20mm swatch, so you can see the riven, honed or brushed surface up close.
  • Flat £5 Delivery: Order up to 2 finishes for one flat delivery charge, however many you choose.
  • Compare Before You Commit: Check colour and texture before ordering a full slab, crate, or bespoke cut.
How Sampling Works

Choose a finish in Step 1 and add it to your cart. To compare two finishes side by side, add your first sample, then pick a second finish and add that too — both ship together under the same £5 flat delivery charge.

Delivery & Turnaround

Samples are dispatched from our Milton Keynes site for a flat £5, whether you order one finish or two. Delivery is to UK addresses only. As 100×100×20mm cut-offs rather than fabricated slabs, samples aren't covered by the crack guarantee or photo service that apply to full slab orders.

Choosing Between Finishes

Riven surfaces keep the stone's natural cleft texture; honed surfaces are ground flat and smooth; brushed sits between the two, with the texture softened but not polished away. Photos and screens don't reproduce true colour, so if you're deciding between our Brazilian Black slate finishes, or between Black and Grey limestone, ordering a physical sample is the most reliable way to check before committing to a full slab or crate.

After Your Sample Arrives

Once you've checked colour and texture, head to the Hearth Slab range to order the full slab or crate in your chosen finish. Trade customers can log in for trade pricing before ordering.
