This slab

The recorded size of a slab in this lot is 115″ × 71″, about 57 square feet. Thickness is 2 cm. The color on record is blue with silver and grey. Natural stone still varies inside that description, so the slab itself is the reference for movement and shade.

The polished finish is reflective and lets the color read clearly. Two centimeters is a standard slab thickness for counters, vanities, and wall cladding.

In the yard

Where it works

For this kind of stone, the usual applications are feature walls, backsplashes, and accent panels. The right use still depends on the finish, the thickness, and how the slab will be cared for after it is installed. Inspiration photos show this stone in a Bathroom.

The material

Onyx is a banded, often translucent stone. It is chosen for feature walls, backlit panels, and accents more often than for a hard-working kitchen. It is softer than granite and should be treated as a decorative stone. Light passing through a slab is part of the look, so thickness and finish both change how the color reads.

About Blue Onyx

Blue Onyx is a rare and visually arresting variety of chalcedony, celebrated for its vibrant sky-blue to deep navy palette. Often characterized by dramatic, flame-like bands of white, orange, and gold, this translucent stone offers a sense of fluid movement. Primarily sourced from high-quality deposits in Argentina and Mexico, it is a favorite for luxury interior applications, including spectacular backlit panels that showcase its internal crystalline artistry. Geologically, its serene blue hue is a result of the Tyndall effect, where light scatters off microscopic particles. Historically, while jet-black is the common association for onyx, these blue specimens have been prized since antiquity for their calming elegance and use in intricate cameos.
