This slab

The recorded size of a slab in this lot is 136″ × 78″, about 74 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. Blue Roma is also known as Blue Deep. Searching either name should lead to this same material. This material is recorded as quarried in Brazil.

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

Where it works

For this kind of stone, the usual applications are kitchen countertops, islands, and vanities. 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 Kitchen and a Powder.

The material

Quartzite begins as sandstone and is metamorphosed into a hard, quartz-rich stone. It is chosen for kitchens and islands when a project wants marble-like movement with more scratch and heat resistance than marble. Density and absorbency still vary by quarry, so sealing should be confirmed on the slab in front of you, not assumed from the name. Movement can change across one lot, which is why the pieces are best compared side by side in daylight.

About Blue Roma

Blue Roma, also known as Blue Deep, is a rare and visually arresting quartzite quarried in the Bahia region of Brazil. It is defined by a sophisticated robin's egg blue or blue-grey background, dramatically interlaced with bold, linear veining in shades of gold, copper, and warm amber. As a metamorphic rock originally formed from sandstone, it offers exceptional hardness, outperforming many granites in resistance to scratches and heat. This durability, combined with its distinct, painterly aesthetic, makes it a premier choice for statement kitchen islands and book-matched feature walls. Interestingly, the stone's complex patterns often create "pools" of color that give it a sense of fluid, natural movement.
