RIVER BLACK QUARTZITE
Geologically rare, this exotic jet-black quartzite has an unusual, bottomless presence. Composed of fine individual grains of black sandstone washed, compressed and welded together by hundreds of millions of years of heat and pressure, the result is unique and timeless.
Strong and durable, the quartzite withstands heavy weather and heavy foot traffic. Its dense structure flawlessly retains carved details and crisp arises. Even when hand finished, it will not refract light, so tool marks lend texture but minimize color variation. No other building stone has such amazing characteristics.
Like all quartzites, the River Black is inert – it is not affected by chlorine and will not discolor with pollution or acid rain. When wet, the stone has a striking jet-black sheen. It is often used as a border to highlight other materials, bringing out the depths of fountains and pools. In fact, modern architecture often draws on its pure color to contrast with glass and stainless steel.
