London Grey, in motion. 🐆

Look past the polish and the slab starts to move: long, layered strokes in charcoal and grey, with a depth that feels almost alive. The finish stays smooth and cool to the touch.

Come see it in person at our showroom!

London Grey has long, layered strokes that look like fur, and a finish as smooth as glass. 🐾

Charcoal and grey move across the slab in soft, directional strokes. Up close, the surface reads like fur, but it feels polished and cool under your hand.

Swipe through to see up close.

London Gray is a natural stone that is pure art! 🖤

Looking at the brushstroke-like pattern, it’s hard to imagine that this slab came naturally this way. It’s hard to imagine that it was once a very large rock, buried under a mountain.

Credit where credit is due: humans extracted these blocks, cut them into slabs, and polished the surface. Humans shipped them across an ocean and store it for display. And humans will cut these slabs and install in your home.

But way before humans were involved, these beautiful black brushstrokes were being formed overtime into pattern we see today.

Let’s just take the time to admire God’s work!

October is a reminder that Black goes with everything 🖤

Mahogany Black is our latest addition to Gramaco.

White crystals in the shape of cat eye poke throughout the brown and gold veining, against a beautiful black background. 🐈‍⬛

Since it’s a natural quartzite, it’s extremely durable. And because its darks it’s easier to maintain.

Visit us at www.gramaco.com and come set an appointment to see this beauty in person.

There’s more to Bronzita than meets the eye. 👁️

Quarried in Brazil, this stone carries a quiet magnetism 𓍹 Natural stone becomes magnetic when it holds magnetite or other iron-rich minerals, whose atomic structure lines up with a magnetic field.

Those same iron-rich minerals are what give Bronzita its warm red undertone, glowing beneath layers of bronze, espresso, and gold veining.

A stone shaped by the earth’s own forces, now ready for yours!

Come see it in person at our Laurel, MD showroom.
