Tulsi japa mala beads from Vrindavana, India.

Tulsi beads are not cheap as Srimati Tulsi Devi appears as a small bush. So her branches are generally not very thick. Therefore to manufacture very large tulsi beads the beads have to be collected from many, many tulsi plants as the only place you can find wood thick enough to make very big beads is at the very base of the trunk of the tulsi plant.
