It is a geometrically exact spherical cactus, depressed at the apex. Generally solitary, this bright green plant has beautiful yellow variegations, which make each specimen unique, you will never find two identical plants. The epidermis is covered with large conical-shaped protruding tubercles, where short golden spines emerge, which are arranged in a star shape. Between the grooves, a short white down is evident, which separates the tubercles. Its lime yellow flowers are small; when bloom, they form a corolla around the apex.
