Overview
Container-direct Brazilian black riven slate hearths, supplied by Bluesky Stone Direct from Milton Keynes and Colchester. Five stock sizes, two thicknesses, two grades — all from the same quarry, all held in stock.
Straight edges, done properly. We cut any straight-sided shape: rectangles, squares, triangles, pentagons and angled corner hearths, plus the two-piece T-set. Angled or corner shape? Email your sizes to sales@blueskystone.com or call 01908 46 46 56 for a quote. If your opening needs a curve (a circle, a teardrop or a rounded front) or a one-piece T, we are not your supplier — and we would rather say so here than waste your time.

One word - FANTASTIC !! A very simple but well crafted website made ordering a straightforward process. Communication from Bhey at Bluesky Stone was excellent and customer care was superb. I collected my order and Brian at the workshop was just wonderful. I was late but nothing was too much trouble. He carefully loaded my stone in through the boot of my car helping me make it secure and even went the extra mile by giving me a bottle of cold refreshing water for my long journey home. Fantastic
Received an incorrect item to begin with but this VERY QUICKLY and SUPERBLY put right by one of the company owners (Leo) who personally drove down to me in London the next day to deliver the correct replacement - this was probably the best customer service I've ever received, which I'm very grateful for. A highly recommended company!
Delighted to find a local company that can supply first class premium product at a competitive price. Easy to order on line using their website and collection notification and process first rate. Highly recommended!

Specification, sizes and weightsSlip rating, strength, 20mm vs 30mm weights
Five stock sizes, 20mm or 30mm, with real weights
| Size | Thickness | Weight |
|---|---|---|
| 900 × 600 | 20mm | 30 kg |
| 900 × 900 | 20mm | 45 kg |
| 1200 × 900 | 20mm | 61 kg |
| 1200 × 1200 | 20mm | 81 kg |
| 1500 × 900 | 20mm | 76 kg |
| 1200 × 900 | 30mm | 91 kg |
| 1500 × 900 | 30mm | 113 kg |
All slabs are calibrated to ±1mm with clean 90° machine-sawn edges. 30mm is made in 1200×900 and 1500×900 only. 1200×1200 comes in Standard grade only. Every slab is a two-person lift and is delivered kerbside on a pallet.
20mm or 30mm is a look choice. 30mm has a thicker edge and a more substantial look, and is heavier to lift. Both thicknesses suit any hearth. As always, check with your installer in case there is a specific reason to choose differently.
Flat enough to pass the credit card test
- 14-Day Crack Guarantee. Fit it within 14 days of delivery. If it cracks in that time, we replace it free. Cut pieces included. Full crates are not covered.
- The credit card test. Every slab must let a standard credit card slide across the riven surface without catching on a ridge. A hearth that rocks under a stove is the fault nobody checks for.
- Container-direct pricing. Brazilian slate bought by the container, not through a UK middleman.
- Free pre-dispatch photo of your actual slab on every Premium order, and on any Standard order with a cutting or finishing service added.
- Free collection from our Milton Keynes workshop (MK8 8DD), booked at checkout, usually ready the next working day.
Standard or Premium: same stone, chosen differently
Both grades are the same stone, the same thickness and the same test results. The difference is how the slab is chosen.
- Standard Grade — the raw character of natural stone, with visible variation in texture, tone and pattern.
- Premium Grade — hand-sorted for even tone, so the face reads as one consistent colour.
Neither grade changes the edge finish: both come with clean 90° machine-sawn edges.
Tested for stove heat, slip and frost
- Slip resistance: PTV 62 dry / PTV 49 wet — low slip risk
- Flexural strength: 19.6 MPa after 48 freeze-thaw cycles
- Water absorption: under 0.50% — high frost resistance
- Surface: subtle natural riven
- Edge: clean 90° machine-sawn as standard
- Colour: graphite grey to black in its raw state. Sealing takes it to a noticeably deeper, darker tone.
- Suitability: designed for the weight and radiant heat of a wood-burning or multi-fuel stove. Not for direct flame contact.
Raw or sealed: arrives the way you want to fit it
- Unsealed — included. Delivered in 3–5 working days.
- Deep Clean & Seal — £30. Deep-cleaned to remove quarry dust, then two coats of Stovax Dressing Oil. This is what takes the stone from grey to black. Allow one extra working day for the oil to dry.

You arrange and pay the return pallet, which costs about the same as delivery. Sealed slabs can come back too; the sealing charge is not refunded.
