Costa Smeralda Heavy Leather Quartzite Slabs in Los Angeles

A 2cm Costa Smeralda quartzite lot in heavy leather — 79″ × 123″ slabs of seafoam green quarried in Brazil.

2cm Costa Smeralda quartzite slab in a heavy leather finish, 79 by 123 inches, with seafoam-green field and delicate white crystalline veining, lifted on the vacuum gantry at the Royal Stone Los Angeles yard

Costa Smeralda takes its name from the Emerald Coast of Sardinia, but the stone itself is quarried in Brazil. A soft seafoam-green field, run through with delicate white crystalline veining and the occasional gold mineral trace — the visual softness of a green marble with the harder, denser structure of a true quartzite underneath.

This lot is 2cm in a heavy leather finish, worked after calibration with diamond-bristle brushes. The texture deepens the green toward true emerald, catches light unlike a flat honed surface, and forgives fingerprints and watermarks in a way polished stone never will. Each slab measures roughly 79″ × 123″ — enough for a waterfall island or a long uninterrupted counter run.
