Grade Guide

STANDARD OR PREMIUM - THE QUICK GUIDE

Brazilian Natural Riven Slate

Same quality. No compromise

Two different looks

OVERVIEW

Standard Grade: The Beauty of Nature

Unselected to showcase the stone's natural, organic variety
Because these slabs are not filtered for uniformity, you can expect a wider spectrum of colour, texture and pattern.
It is the perfect choice for those who appreciate a unique, organic look.

Premium Grade: Curated Consistency

Our Premium slabs are hand-selected
Individually photographed for their visual harmony.
Choose Premium if your project requires a highly consistent appearance and more predictable patterning.

Regardless of grade - ALL slabs must pass the surface smoothness test - see video below

PREMIUM GRADE

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: To maintain integrity, Premium slabs are packed in their own dedicated crates, separate from standard inventory.

These photos, taken by our quality control team, provide a clear look at the uniform texture and refined finish of our hand-selected slabs

STANDARD GRADE

Celebrating the Unfiltered, Organic Character of Natural Stone.

What to expect from our Standard Grade

Natural Diversity: A beautiful, wide spectrum of colour, tone, and pattern.
Unique Character: A less homogeneous appearance, ensuring 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 to ensure safe delivery.

These warehouse photos, captured by our quality control team, provide a transparent look at the natural variation and authentic character you can expect with your order.

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.

Our Signature Quality Benchmark

To ensure a surface that is level and comfortable to the touch, we perform the “Credit Card Test.” This assessment guarantees:

Zero Sharp Ridges: A flush, surface-level.
Seamless Transitions: No excessive roughness or catching.
Tactile Perfection: If a credit card cannot slide freely across the entire slab, it doesn't leave our facility.
