Graphic Black Tourmaline is a combination of two of my most favorite grounding and protection materials Black Tourmaline and Smoky Quartz.  Black Tourmaline is a Root Chakra stone for energetic and physical protection.  Smoky Quartz is one of the most powerful energetic cleansing and grounding crystals.  This ability to clear negative energy allows for a strong grounding connection to the Earth.  This strong energetic stability is particularly helpful for those who suffer from depression and anxiety.  It's also helpful for protection and detox of Electromagnetic fields and radioactive exposure.  This piece measures 4.5 inches tall and weighs 1 lb 2 oz.
