Slabs - VALONGO BLACKTM

VALONGO BLACK™ Slate has become one of the most sought-after building materials in today's homes due to its smooth, satin texture and durability. The appearance and composition offer a warm aesthetic to any room; whether the architectural theme is modern or rustic.

Unlike other black stones, VALONGO BLACK™ slate is low in porosity; exhibits very little grain, and won't show stains or fingerprints. Its uniqueness, durability, and strength make it a great choice for kitchen counter tops, bath vanities, and floor tile. With an optional cleft or honed finish.

VALONGO BLACK™ is suitable for any design. To compliment your counter top, we also offer solid block sinks, shower pans, and custom bathtubs.

VALONGO BLACK™ cleft slate is also known as ‘natural slate’. It has a rough, textured, and inconsistent surface. 

VALONGO BLACK™ slate's resistance to acids gives it exceptional stability and durability.

VALONGO BLACK™ natural cleft slate slabs are The Real BLACK slate.

VALONGO BLACK™ honed slabs show interesting characteristics of Fools Gold (Pyrite), with small off white or black markings and an occasional larger marking, which adds graceful character.
