Red Onyx is quarried in Mexico. This onyx ranges from deep burgundy & purples to reds & oranges, with some pinks and translucent white thrown in . Our polished field tile comes in a 12×12 size, and we carry tubled accents & mosaics to match. We also have honed slabs available. Red Onyx can be used in both interiors and exteriors, on both on floors and walls.
