Two natural stones with real personality, from the grounded, tactile beauty of slate to the dramatic glow of backlit onyx.
Slate
When you’re weighing countertop materials, natural stones like granite and marble get most of the attention, but slate is an affordable and stylish option worth a look. It’s a fine-grained metamorphic rock made of repetitive layers, and it’s long been used for roofing and flooring because it’s durable, fireproof, and barely absorbs water, with a rate of just 0.4 percent. Yes, it’s the same material as old chalkboards. As a countertop, slate is hard, less porous than many stones, and resists heat beautifully, handling both intense heat and cold while changing temperature slowly.
Its beauty is in its simplicity, merging easily with modern, rustic, transitional, or traditional spaces. Colours come from its mineral composition and range from rich dark grays to lighter grays, blues, greens, reds, browns, and purples, often with subtle accents that make each piece unique. Chipping or scratching at the edges can happen and edges can be sharp, so take care with heavy objects and consider rounding the corners for safety.
To clean slate, a damp microfiber cloth handles dust and spills nicely. Wipe it dry afterward to prevent mineral deposits or water spots, and steer clear of abrasive cleaners and tools, along with products containing wax, lemon, or vinegar. Ask your sales associate about recommended stone cleaners and whether your slate should be finished with a penetrating sealer for extra protection.
Onyx
Onyx is a showstopper. This natural stone has a bold, moving appearance, and its most remarkable trait is translucency, which means it can be backlit to create a genuinely dramatic focal point. It comes in a wide spectrum of colours, from blue, green, purple, gold, red, and orange to gray, brown, and softer beiges and whites, and because it’s natural, every slab is unique.
That beauty does come at a price, as onyx is one of the most expensive natural stone countertops. It’s lightweight compared to other stone and quarried in smaller slabs, which gives you real design flexibility, but it’s also softer and prone to scratching and cracking. For that reason, it tends to shine in bar tops, backsplashes, bathroom counters, and vertical applications more than in busy kitchens. To keep it looking its best, onyx needs regular sealing and often a specific stone cleaner for everyday care.
The Character Of Onyx
Common Questions
It can be a great one. Slate is hard, heat-resistant, low in water absorption, and more affordable than many natural stones, with a tactile, understated look that suits many styles.
It depends on the slate. Some benefit from a penetrating sealer for added protection, so it’s worth asking about your specific stone. Either way, avoid abrasive or acidic cleaners.
Onyx is translucent, so it can be backlit for a dramatic glow that no other stone offers, along with bold natural colour and movement that make each slab unique.
Because onyx is softer and more fragile, it’s best suited to bar tops, backsplashes, bathroom counters, and vertical surfaces rather than heavy-use kitchen counters.
It’s one of the pricier natural stones. It’s quarried in smaller, lightweight slabs, which adds design flexibility, but the material itself sits at the higher end.
