Named directly after the Kuppam region of Andhra Pradesh where it is quarried, this stone carries notable variation in colour and veining even between blocks extracted from the same quarry — a characteristic that defines the individuality of each slab. The light grey-green ground is marked by shifting clouds of darker and lighter tones, drawing a structural parallel with Viscount White Granite in terms of texture and surface behaviour. Petrologically, the stone is classified as a gneiss of the Precambrian period under European standards, distinguished by its flaser texture— a geological detail that speaks to both its age and its enduring surface hardness.
