This Narmada Shiva Lingam carries the sign of Shiva across the head. It has a deep tone of purple underneath. Several bindis appear(markings that appear as circles)representing spiritual enlightenment.
What also makes this lingam unique is that it has a yellow bindi exploding from the end of a marking that starts from the top of the Shiva Lingam. These are hard to find but in this recent shipment we were blessed!
