HAND-SELECTED

Petra Onyx travels across the world to personally source exceptional natural stones from the most renowned quarries. Each selection is made with a focus on the stone’s distinctive character and timeless story, ensuring every piece reflects the heritage and artistry of nature itself.

TIMELESS CRAFTSMANSHIP

At Petra Onyx, we prioritize quality over quantity. Each slab we offer is carefully chosen for its exceptional grade — only those that meet our highest standards of 9 or 10 in quality make it into our collection. We refuse to compromise by stocking materials that fall short of excellence, regardless of market demand.

ABSOLUTE TRANSPARENCY

At Petra Onyx, transparency defines our approach. Our online and in-gallery prices are always the same, so you know exactly what you’re paying for — materials and craftsmanship, clearly separated. Each stone is professionally photographed in high fidelity, capturing its true color and character, ensuring that what you see is precisely what you receive.

UNFORGETTABLE JOURNEY

From our showrooms, where each stone is showcased in a museum-like setting, to our dedicated team of experts offering personalized guidance and exceptional service — Petra Onyx is committed to creating an experience that is as inspiring and memorable as the stones themselves.
