Echinometra mathaei grows to a test diameter of about 5 centimetres (2.0 in). The colour is quite variable but the test is usually a dark colour. The spines are sometimes green and purple with purple tips or entirely green with purple tips but this sea urchin can be distinguished from other species by a characteristic pale ring at the base of each spine.
