Double Terminated Obsidian helps energy flow both ways; as energy enters at one point, it is transmuted and emanated through to the other point, helping to diffuse and dispel negative and low energy.  This makes it an excellent tool for cleansing and balancing the chakras, and bringing energy protection.
 
Blue African Turquoise has been used in many ancient cultures as a highly sacred stone due to its energy centring on luck, protection and power.  Believed to purify energy, it is still used in many cultures as a stone to dispel negative energy against outside influences. African Turquoise is particularly beneficial for relieving physical and emotional exhaustion and depression and is used in crystal therapy to calm anxiety and panic attacks. For the physical being, it is often used to the Throat Chakra and sooth for mouth and throat conditions.
