IMPALA BLACK GRANITEImpala Black granite has a moderate grain and is black in colour, but it has several different tones that give it a more uneven appearance. Impala Black Granite is also available in honed, leather satin, river washed antique, thermal flamed, brushed, and sandblast finishes, but a gloss polished surface gives it the best aesthetic appeal.
