About Cosmic Black
Its dramatic pattern stands out when a whole slab is used for a feature wall, counter or kitchen island. Every slab is different, so we recommend choosing it in person.
Where is it used?
Hard and resistant to water and frost, granite is used inside and out: facades, floors, stairs, landscape paving and kerbs, as well as kitchen and table tops.
Good to know when choosing
The position and amount of the wave pattern differs from slab to slab, so for countertops and feature walls where one large piece is used, it is best to choose the slab in our yard. Polishing makes the contrast between the black base and white pattern even sharper.
