The faces or mukhi of a rudraksha bead range from 1 to 21 and, sometimes even more which is common in Indonesia/Jawa origin beads. Furthermore, a rudraksha bead which is mostly a single fruit sometimes has a natural twin formation, known as the Gauri-Shankararudraksha. There is also a case where a twin formation bead doesn’t have two distinct beads rather, one bead overlaps the other. Such bead is popular as Garbh-Gauri rudraksha. Rarely, it can also be a triple formation bead which is recognized as Trijutirudraksha. When a rudraksha bead has a peculiarly distinct elevated formation (trunk-like) on its surface, it is known as Ganesha rudraksha.
