Same quality.No compromise.Two different looks.
Standard or Premium — the quick guide to how we grade Brazilian Natural Riven Slate, and exactly what to expect from each.
The beauty of nature
- Unselected to showcase the stone's natural, organic variety.
- Not filtered for uniformity — expect a wider spectrum of colour, texture and pattern.
- The perfect choice for those who appreciate a unique, organic look.
Curated consistency
- Hand-selected from production for the most desirable patterns and tones.
- Individually photographed for visual harmony before it ships.
- Choose Premium if your project needs a highly consistent, predictable appearance.
Hand-selected for uniform appearance
Our 5-step premium selection process
Hand-selection — we filter production for slabs with the most desirable patterns and tones.
Surface calibration — we ensure a smooth, uniform finish that eliminates sharp ridges.
Strict tolerance testing — we apply the Credit Card Test to guarantee a perfectly level surface.
Digital approval — every slab is photographed and sent to our team for final aesthetic verification.
Secure logistics — Premium slabs are packed in their own dedicated crates, separate from standard inventory.
Celebrating natural character
What to expect from Standard grade
Natural diversity — a beautiful, wide spectrum of colour, tone, and pattern.
Unique character — a less homogeneous appearance, so no two slabs look identical.
Surface calibration — we ensure a smooth, uniform finish that eliminates sharp ridges.
Strict tolerance testing — we apply the Credit Card Test to guarantee a perfectly level surface.
Secure logistics — all materials are packed in designated, reinforced crates for safe delivery.
Precision you can feel: the credit card test
While beauty is in the eye of the beholder, the quality of a finish is undeniable. Regardless of the grade you choose, every single slab we produce must meet the same rigorous smoothness standards.
- Zero sharp ridges — a flush, surface-level finish.
- Seamless transitions — no excessive roughness or catching.
- Tactile perfection — if a credit card can't slide freely across the slab, it doesn't leave our facility.
Grade guide FAQ
What's the actual difference between Standard and Premium?
It's 100% visual. Both grades are cut from the same rock and are equally durable. Standard Grade has heavy natural character — varied shading, raw clefts, and rustic mineral tracking. Premium is hand-sorted for an ultra-flat surface and uniform, minimalist colour.
Is the cheaper Standard grade lower quality?
No. We don't sell structurally weak stone. Every single slab — regardless of price — passes our Credit Card Test before it leaves the yard, guaranteeing zero sharp ridges and smooth, flush edges on every tier.
Can I hand-pick a specific slab from the photos?
No. To keep pricing fair for everyone, we ship straight from the crate by volume. If your project needs an ultra-consistent look with zero surprises, choose Premium rather than Standard.
Will a new order today match an old order from months ago?
We can't guarantee it with natural stone — geological veins vary with every container we import. If matching an existing order matters, order any extra you need upfront rather than reordering later.
Does Premium come with the same crack guarantee?
Yes. Every slab we sell, Standard or Premium, is covered by the same 7-day crack guarantee — the grade only affects appearance, never the guarantee.
