Amarillo Martin Granite is a warm yellow to golden natural stone, predominantly quarried in the Badajoz area of the Extremadura region in Spain. This granite is renowned for its dominant golden-yellow background, which ranges from soft pale yellow to deeper golden tones, sometimes featuring subtle whitish or light beige shades. It is a compact and medium-grained crystalline composition primarily consisting of interlocked quartz, feldspar, and minor dark minerals.
