Chakra Mala is a strung mala (no knots between beads).
 
Lava Stone is a grounding stone strengthening one's connection to Mother Earth, giving strength and courage, and manifests stability through times of change.  A calming stone, Lava Stone is useful in dissipating anger. It promotes positive changes where needed in behavioural issues.

In addition, Lava Stone is a wonderful essential oil diffuser - add a few drops of your desired essential oil and enjoy the added therapeutic benefits.
