The texture of agate rock is typically banded, with alternating layers of different colors and textures. The bands may be straight, wavy, or even spiral. The color of the bands is determined by the minerals present in the rock. Common colors include red, orange, yellow, brown, and green. Agate can also be translucent or opaque. The hardness of agate is 6.5 to 7 on the Mohs scale, making it a relatively durable rock.
