This slab

The recorded size of a slab in this lot is 129″ × 77″, about 69 square feet. Thickness is 2 cm. The color on record is grey with silver, black, and brown. Natural stone still varies inside that description, so the slab itself is the reference for movement and shade.

The leather finish is lightly textured, with a softer look than a full polish. 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.

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 Platinum

Platinum, also known as Hyperion or Platinum Silver, is an elite quartzite primarily quarried in the geological formations of Brazil. This natural stone is celebrated for its sophisticated silver-gray palette, featuring a luminous background interlaced with soft, flowing charcoal and white veining. As a true quartzite, it offers exceptional hardness and acid resistance, making it an ideal, low-maintenance alternative to marble for high-traffic surfaces like kitchen countertops. Interestingly, its dense crystalline structure often provides a subtle pearlescent sheen under direct light, reflecting the metallic elegance suggested by its namesake while providing the legendary durability of granite.
